Abiotic and Biotic Factors Affecting Crop Growth and Productivity: Unique Buckwheat Production in Egypt

Abiotic and Biotic Factors Affecting Crop Growth and Productivity: Unique Buckwheat Production in Egypt

Prevailing parasitic diseases affecting Oreochromis aureus in Lake Burullus.

Lake Burullus is an important source of fish production in Egypt; it produces 20.5% of the Egyptian fisheries' production. There is intense controversy about the heavy metal pollution in Burullus water and its effects on fish health and safety for human consumption. Heavy metals represent a major concern for aquatic life and could negatively affect fish health. Agricultural and industrial water drainage represents a considerable part of the lake water supply. The present work was conducted to determine heavy metal concentrations in lake water and blue tilapia Oreochromis aureus musculature. Water samples were collected from six locations to determine cadmium, copper, lead, zinc and iron. Sixty O. aureus fish samples were also collected from the same sampling points to assess the prevalent parasites infesting fish and to determine the heavy metal (Cd, Cu, Pb, Zn and Fe) concentrations in fish musculature then study the relationship between heavy metals concentration and prevailing fish parasites. Results indicated that 53.34% of the examined fish were infested with encysted metacercaria. Centrocestus formosanus, Prohemistomum vivax, and Euclinostomum heterostomum were retrieved from gills, musculature, hepatopancreas and the posterior kidney. The parasitic intensity in fish tissues was between 1 and 9 cystg-1. Centrocestus formosanus was identified using the polymerase chain reaction in the gill tissues of 16 fish. The gill parasitic copepod Lamproglena monodi was identified in one fish. Degenerative changes such as thickening, corrugation, and destruction of gill filament are the most dominant pathological changes in infested fish gills. Heavy metal concentrations in water samples were at normal levels, except for copper and iron in the southern part of the lake. All heavy metals in fish musculature were below the permissible limits. The parasitic infestation was more dominant in the northern part of the lake than in the southern region; this could be due to elevated copper concentration in the southern part of the lake that could negatively affect the survival of the first intermediate host and parasite cercaria. In conclusion, captured fish from Lake Burullus were safe for human consumption, and heavy metal pollution in lake water does not represent a severe risk.

Potential Improvements in Crop Production in Egypt and Implications for Future Water and Land Demand

Similar to numerous water- and data-scarce regions, Egypt confronts a critical challenge in sustaining food production for its rapidly growing population. Consequently, the country’s water and land resources are under considerable stress and require careful management. About half of Egypt’s both annually harvested areas and renewable freshwater are allocated for cultivating rice, maize, wheat, and berseem clover. However, the extent to which crop production might be improved and how this would impact future water and land requirements remains poorly understood. We analyzed potential improvements in the production of these crops and quantified their future water and land requirements under different scenarios. Potential improvements were detected through percentile analysis in three remote sensing-derived performance indicators for each crop in the Nile Delta’s Zankalon region: (i) crop yield, (ii) crop water productivity, and (iii) transpiration fraction (transpiration to actual evapotranspiration, T/AET). We applied detected improvementsto construct plausible scenarios for Egypt’s water and land requirements to sustain domestic crop production until 2050. Our findings indicate limited potential to improve T/AET (< 4%). However, improvements of up to 27% for crop yields and up to 14% for water productivity are possible. To meet the production targets by 2050, national production must increase by 128, 78, 69, and 71% above the 2016–2020’s average for rice, maize, wheat, and berseem, respectively. Depending on the improvement levels in the developed scenarios, a total harvested land area between 5.3 and 6.4 million ha will be required by 2050, with 18% allocated to rice, 28% to maize, 36% to wheat, and 18% to berseem. Associated freshwater requirements will amount to 59–68 billion cubic meters, divided into 23% for rice, 34% for maize, 28% for wheat, and 15% for berseem. Interventions increasing yields and water productivity will benefit more the summer (rice and maize) than the winter crops (wheat and berseem). We discuss likely interventions for meeting these requirements and for sustaining the supply of these crops in Egypt.

Effectiveness of biofertilizers foliar application on yield and quality traits of flax (Linum usitatissimum L.)

Flax is considered to be one of the most significant dual-purpose crops for oil and fiber production in Egypt and worldwide. Biofertilizers have a substantial impact on various metabolic processes, including increased photosynthesis, endogenous hormone levels, ion absorption, nucleic acid synthesis, and protein synthesis. These factors collectively contribute to the growth and development of plants. Therefore, this study aims to investigate how three biofertilizers (Algae extract, CMS as a by-product of yeast, and Metalosate multi minerals as amino acids) can enhance both the quantity and quality of flax seed yield under sandy soil conditions. Two field experiments were conducted at the Experimental Station of National Research Centre in Nubaria District, Behira Governorate, Egypt during two seasons (2021/2022) using a randomized complete block design (RCBD). The results revealed significant differences among all tested biofertilizers in terms of various characteristics studied in flax. Foliar application of algae extract at a rate of 1.50 ​mL/L resulted in an increase in seed yield (ton/ha) by 26.69% & 19.89%, straw yield (ton/ha) by 8.08% & 17.12%, and oil yield (kg/ha) by 47.72% & 33.69% compared to the control group during both seasons respectively. Foliar applications of algae extract at a rate of 1.50 ​mL/L along with CMS at a rate of 5 ​mL/L and amino acids at a rate of 1.50 ​mL/L demonstrated significantly higher macronutrient contents (N, P, K), micronutrient contents (Fe, Zn, Mn), seed oil content, and protein content in flax seeds during both seasons. The highest values for seed oil content and protein content % were obtained through foliar application of amino acids at a rate of 1.50 ​mL/L. It can be concluded that foliar sprays with these biofertilizers effectively improved flax performance by increasing seed straw and oil yields, nutrients oil, protein and fatty acids seeds contents.

Sustainable fish production in Egypt: towards strategic management for capture-based aquaculture

This study assessed the sustainability of capture-based aquaculture (CBA) practices in Egypt, identified challenges, and proposed solutions to enhance sustainability. It relied on published data and studies, revealing that these practices are globally widespread for cultivating a diverse range of marine and freshwater species based on wild seed collection. The assessment showed that these practices in Egypt cultivate a variety of fish species. In 2021, they contributed to approximately 34% of the total aquaculture production, amounting to an estimated value of USD 1.476 billion, representing about 57% of the total value of the aquaculture sector. Additionally, these practices provided around 106,022 full-time jobs. Official fishery statistics have not indicated any negative impact of CBA on fish stocks over the past 30 years. Measures aimed at enhancing the sustainability of these practices included granting licenses for the collection of wild seeds for specific species under specific regulations. Facilitating licensing procedures for hatcheries, providing incentives, and promoting farmers’ preferences for hatchery seed were also part of these measures. Furthermore, these actions include facilitating access to financing under favorable conditions, selective breeding, training hatchery workers in best management practices, implementing biosecurity measures, and establishing an accurate statistical system. The implementation of the proposed plan to transition from capture-based aquaculture to hatchery-based aquaculture will contribute to achieving sustainability for both aquaculture and fisheries.

Non-metallic decorative inlays in La Tène jewellery - contribution of archaeometry to the understanding of production technologies

The study provides a detailed investigation into several representatives of La Tène jewellery. Primarily, it deals with non-metallic decorative inlays from the Late La Tène period, particularly with their application on a metal base. Unique artefacts have been selected for the study, all coming from the Czech Republic and Slovakia. A prime representative of the finds is a torc coming from a La Tène burial site in Prague (Czech Republic, Central Europe). In this geographical context, such finds are rather exceptional. The torc examined is remarkable both in terms of its origin and the production technology utilised, namely the application of decorative inlays made of red opaque glass. Available literature classifies this decorative element as an enamel technique. The highly specific type of red soda high-lead glass applied there was examined using LA-ICP-MS. Based on the trace elements detected, it can be established that the glass is most likely related to contemporary Egyptian production. Other items of the artefact set consist of two Münsingen brooches from Moravia and an exceptional brooch from Slovakia. The latter find was found to be decorated with coral (as confirmed by Raman spectroscopy). Besides identifying the materials of the decorations, we were also able to characterize the binder between individual decorative inlays and their metal base. The analysis of the binder has revealed the presence of birch tar (determined by FTIR and GC/MS). The results obtained expand the knowledge about the production technologies applied to the jewellery from the La Tène period.

CBAM, Hydrogen Partnerships and Egypt’s Industry: Potential for Synergies

Abstract This article examines the hydrogen partnerships between Germany, the EU and Egypt in the context of the EU’s Carbon Border Adjustment Mechanism (CBAM). Germany, the largest future hydrogen importer in the EU, and Egypt, a country with an ambitious hydrogen strategy, are developing a partnership to boost renewable hydrogen production in Egypt. However, high funding costs are a barrier to capital-intensive investments in hydrogen projects, in particular in emerging economies. CBAM provides an incentive to decarbonise but faces resistance in emerging economies as it may undermine the competitiveness of emission-intensive local production. Combining industrial development with hydrogen production could be a more promising partnership strategy than a narrow one focused only on producing hydrogen for export to the EU. By aligning hydrogen partnerships with local development goals, CBAM acceptance can be improved, as industrial development could be climate-friendly, making exports into the EU easier while creating new value chains to the benefit of EU producers.

Apple cider vinegar exhibits promising antibiofilm activity against multidrug-resistant Bacillus cereus isolated from meat and their products.

Bacillus cereus (B. cereus) biofilm is grown not only on medical devices but also on different substrata and is considered a potential hazard in the food industry. Quorum sensing plays a serious role in the synthesis of biofilm with its surrounding extracellular matrix enabling irreversible connection of the bacteria. The goal of the current investigation was to ascertain the prevalence, patterns of antimicrobial resistance, and capacity for B. cereus biofilm formation in meat and meat products in Egypt. In all, 150 meat and meat product samples were used in this study. For additional bacteriological analysis, the samples were moved to the Bacteriology Laboratory. Thereafter, the antimicrobial, antiquorum sensing, and antibiofilm potential of apple cider vinegar (ACV) on B. cereus were evaluated. Out of 150 samples, 34 (22.67%) tested positive for B. cereus. According to tests for antimicrobial susceptibility, every B. cereus isolates tested positive for colistin and ampicillin but negative for ciprofloxacin and imipenem. The ability to form biofilms was present in all 12 multidrug-resistant B. cereus isolates (n = 12); of these, 6 (50%), 3 (25%), and 3 (25%) isolates were weak, moderate, and strong biofilm producers, respectively. It is noteworthy that the ACV demonstrated significant inhibitory effects on B. cereus isolates, with minimum inhibitory concentrations varying between 2 and 8 μg/ml. Furthermore, after exposing biofilm-producing B. cereus isolates to the minimum biofilm inhibitory concentrations 50 of 4 μg/ml, it demonstrated good antibiofilm activity (>50% reduction of biofilm formation). Strong biofilm producers had down-regulated biofilm genes (tasA and sipW) and their regulator (plcR) compared to the control group, according to reverse transcriptase quantitative polymerase chain reaction analysis. Our study is the first report, that spotlights the ACV activity against B. cereus biofilm and its consequence as a strong antibacterial and antibiofilm agent in the food industry and human health risk.

The usage of the autoregressive integrated moving average model for forecasting milk production in Egypt (2022-2025).

Milk is considered one of the most important capital goods and essential sources of animal protein in the diet of the Egyptian family, as well as an effective means to improve the economic condition of farmers, considering this important view, the policymakers need accurate and advance information regarding future supply for planning on the both short and long term. The study aims to forecast the production of milk in Egypt during the period from 2022 to 2025 using the Autoregressive Integrated Moving Average (ARIMA) model using time series data of milk production (MP) (1970-2021) obtained from the Central Agency for public mobilization and statistics (CAPMS). Augmented Dickey-Fullar Unit Root test, Partial autocorrelation function (PACF), and Autocorrelation function (ACF) of the time series sequence were used to judge the stationarity of the data. After confirming the stationarity of the data, the appropriate ARIMA model was selected based on certain statistical parameters like significant coefficients, values of adjusted R-squared, Akaike information criteria (AIC), Schwarz criterion (SC), and Standard Error of Regression. After the selection of the model based on the previous parameters, the verification of the model was employed by checking the residuals of the Correlogram-Q-Statistics test. The most fitted model to predict the future levels of MP in Egypt was ARIMA (1, 1, and 3). Using the ARIMA (1, 1, 3) model, it could be forecasted that the production of milk in Egypt would show an increasing trend from 6,152.606 thousand tons in 2022 to 6,360.829 thousand tons in 2025.

Screening for High-Yielding Barley Genotypes with Adequate Foliar Disease Resistance in North Delta of Egypt

In addressing the global impact of fungal foliar diseases on barley yield; namely powdery mildew, net blotch and leaf rust, this study undertakes a robust phenotypic and genotypic evaluation. A set of 132 barley genotypes, were evaluated under conditions of elevated pathogenic stress. Multivariate analyses revealed statistically significant inter-genotypic variances for all measured agronomic and pathological traits, concomitant with noticeable seasonal effects. In a nuanced observation, the genotype-by-season interaction elicited significant impacts across a plethora of traits, with the exception of spike length and thousand grain weight. From a quantitative genetics perspective, broad-sense heritability estimates were remarkably high: 97.2% for powdery mildew, 89.3% for net blotch, and 97.5% for leaf rust. Concurrently, genetic advance estimates for biological yield, grain yield, powdery mildew, net blotch, and leaf rust registered in the high to very high categories. Correlational analyses substantiated a positive linear relationship between grain yield and maturity date, plant height and biological yield. Using biplot analysis, 12 genotypes were identified that showed high yield and resistance to powdery mildew, net blotch, and leaf rust. Thus, investigation illuminates the possibility of deploying high-yielding, disease-resistant barley cultivars as an effective strategy for mitigating the deleterious effects of fungal foliar pathogens on barley production in Egypt.

Regulatory Impact Analysis for the Risk Based Lot Release Policy for Biological Products in Egypt

For public health and lifesaving, timely access to high-quality biological products is essential. However, barriers including resource scarcity, limited human capacity, and complex supply chains impede this goal. National regulatory authorities should enhance their frameworks and move forward for regulatory convergence and harmonization &amp; enhancing reliance practice in order to address these concerns. A risk-based lot release policy is one of the enablers that ensure implementation of smart regulations and best practices was employed by Egyptian drug authority (EDA) to boost the effectiveness of the lot release framework while upholding safety, efficacy and quality criteria. The legal framework for lot release in Egypt was examined using a regulatory impact analysis method. With a considerable impact on time and cost savings, as well as a better net benefit value, the new risk-based lot release policy has the potential to greatly increase the efficiency of Egypt's LR regulatory system for biological products. Nevertheless, significant challenges and unexpected consequences were also noted, including the need for ongoing capacity building and growing regulatory requirements based on best practices. The findings have major reflections for drug policy makers and regulators looking to enhance their biological product regulatory systems; since the policy's benefits outweigh these possible challenges. This paper offers a full examination of the risk-based lot release policy used by the EDA, Egypt for biological products, assisting in understanding both the benefits and challenges of this approach.

Characterization and identification of Lactobacillus rhamnosus and Enterococcus durans as probiotic potential isolated from selected dairy products in Egypt

AbstractProbiotics are living microbes that promote consumer health when taken in significant quantities with food. The aim of this research was identifying the probiotic properties (in vitro) of lactic acid bacteria (LAB) isolated from traditional fermented dairy products from Egypt (Kareish cheese, Rayeb milk, local yoghurt and buttermilk). Only 13 isolates were characterizes as Gram-positive, endospore-negative, non-motile and catalase-negative with small round colonies. All 13 isolates were examined for its probiotic properties (antibacterial activity, antibiotic susceptibility, acidity and bile salt tolerance). All isolates showed antimicrobial effect against bacterial pathogens tested. LAB-6 had a significantly larger inhibition zone followed by LAB-2 and LAB-3. Moreover, LAB-6 was the most resistant to all antibiotics tested. Seven of thirteen isolates were Penicillin-resistant. Only LAB-3 exhibited strong chlorophenicol resistance. The isolates that affect pathogens and resistant to antibiotics were found acid-and-bile salt-tolerant in varying degrees. All bile and acid tolerant isolates revealed variable antibiotic sensitivity. Regarding to previous results, only three selected isolates (LAB-2, LAB-3, and LAB-6) had their 16SrRNA gene sequences compared to Gene-Bank. Isolate LAB-2 was found in the genus Lactobacillus, with 98.7% similarity to L. rhamnosus OP268116 strain GCM20300. LAB-3 was Lactobacillus, with 98.9% similarity to L. rhamnosus OP268117 strain 6481. Comparative genomic research demonstrated very minimal changes between isolate LAB-6 and Enterococcus durans OP268118 strain CAU5334. Thus, these isolates could be used as food biopreservatives, starter cultures in the fermented dairy products and cheese industry, or novel strategies to combat the rising number of antibiotic-resistant pathogens in human infections.
