Increase In Industrial Demand Research Articles

Comparative Analysis of Tapping Technique in Indian Ash Tree, Jhingam (Lannea coromandelica) (Houtt) (Merr) and Arjun (Terminalia arjuna) (Roxb) in Pakhanjure Uttar Bastar Kanker Region of Chhattisgarh

Gum and resin from non-wood forest products (NWFP) play a crucial role in the income and livelihoods of small-scale farmers. Recently, there has been a significant increase in industrial demand for these products. Therefore, a study of “Tapping Technique” was conducted in 2022–23 to assess various traditional, mechanical, and gum enhancer applications for enhancing gum and resin production during both the winter and summer seasons. This study revealed that the Jhingam tree demonstrated excellent potential for gum production throughout the year. Specifically, the application of a 2% ethylene-based gum enhancer injected via the drill method at 1-meter height from the ground in trees with over 90 cm diameter significantly increased gum production quantity, rate, and quality. Analysis of physiochemical properties showed that this treatment resulted in higher moisture content, pH, and bulk density (0.76-0.78) while reducing tapped density. The Fat and protein content were also higher compared to other methods. The angle of repose indicated good capsule-filling properties at 31.87%. On the other hand, the Arjun tree exhibited lower gum production potential compared to Jhingam, with most production occurring during the summer. Similar to Jhingam, the application of a 2% ethylene-based gum enhancer reduced the moisture content, pH, and bulk density while increasing the fat and protein content. Both gums showed high solubility in hot water, with a viscosity at 6.1 cP (high) at 100 rpm and 1 cP (low) at 10 rpm in a 1% solution. The angle of repose for Arjun gum was 25.33%.

A roadmap to improve usage items to enhance the operational effectiveness of occupational safety and health management expense in Korean construction.

Occupational safety and health management expense (OSHE) in construction industry is a statutory expense used for the purpose of preventing occupational accident and health disorders for construction workers, and the detailed usage standard is stipulated in the law and regulations governed by the Ministry of Employment and Labor in Korea. Previous studies focused on improvement of the accounting rate of OSHE and institutional improvement to secure usage transparency, but analysis showed that the review of improvement directions for usage items was insufficient. Considering recent trends, such as the increase in industrial demand to improve existing usage items and the introduction of various smart safety products incorporating the Fourth Industrial Revolution technology, it is expected that it will be necessary to review ways to improve the usage items to enhance the operational efficiency of OSHE. Accordingly, this study collected opinions from various stakeholders, and presented a roadmap to improve usage items of OSHE through importance-performance analysis (IPA) based on the data. This study is expected to meet the needs demanded by industry, and to be utilized as a reference for policy preparation to enhance the safety of construction sites.

Bioactive Polysaccharides from Seaweeds.

Bioactive compounds with diverse chemical structures play a significant role in disease prevention and maintenance of physiological functions. Due to the increase in industrial demand for new biosourced molecules, several types of biomasses are being exploited for the identification of bioactive metabolites and techno-functional biomolecules that are suitable for the subsequent uses in cosmetic, food and pharmaceutical fields. Among the various biomasses available, macroalgae are gaining popularity because of their potential nutraceutical and health benefits. Such health effects are delivered by specific diterpenes, pigments (fucoxanthin, phycocyanin, and carotenoids), bioactive peptides and polysaccharides. Abundant and recent studies have identified valuable biological activities of native algae polysaccharides, but also of their derivatives, including oligosaccharides and (bio)chemically modified polysaccharides. However, only a few of them can be industrially developed and open up new markets of active molecules, extracts or ingredients. In this respect, the health and nutraceutical claims associated with marine algal bioactive polysaccharides are summarized and comprehensively discussed in this review.

Biochemical and molecular characterization of a novel dye-decolourizing peroxidase from Raoultella ornithinolytica OKOH-1

The increase in industrial demand for peroxidases has necessitated the search for novel peroxidase with excellent industrial versatility. Raoultella ornithinolytica OKOH-1 is a new ligninolytic bacteria with peroxidase production potential. However, there is paucity of information on characterization of peroxidase from Raoultella species and its application potential in bioremediation. In this study, we characterized peroxidase from Raoultella ornithinolytica OKOH-1 (RaoPrx) for the first time using biochemical approach and bioinformatics; and as well investigated the dye-decolourization potential of the enzyme. RaoPrx oxidized various substrates, with pyrogallol giving the optimum activity. It had an optimum activity at pH 6 and was stable over a pH range of 5.0–7.0 with residual activity of above 40% after 120 min of incubation. The enzyme showed an optimum activity at 50 °C and was very stable at higher temperatures (50–70 °C) with residual activity of above 70% after 120 min. The enzyme was remarkably stable at 50 °C as it retained over 90% of its original activity after 120 min. The peroxidase activity was enhanced by Ag+, Cu2+, Zn2+and Fe2+, but was inhibited by Ca2+, Mg2+, Ba2+, Al3+, Co2+, NaN3 and EDTA. Furthermore, molecular characterization suggests RaoPrx as a novel dye-decolourizing peroxidase (DyP-type) family belonging to Class B, with estimated mo1ecular weight of 17.587 kDa and isoelectric point of 4.51, this is further confirmed by its remarkable dye-decolourizing activity on congo red and melanin in this study. This, therefore, indicates its application potential in textile dyes remediation and development of cosmetic agent.
