Duration of Light Exposure Using White Light-Emitting Diode (LED) on the Performance of White Oyster Mushroom (Pleurotus ostreatus L.)

Background: In the dynamic world of mushroom cultivation, optimizing growth conditions is paramount for maximizing yield and quality. This research sought to evaluate the influence of varying hours of exposure to white light through light-emitting diodes (LED) on growth and yield performance of white oyster mushroom (Pleurotus ostreatus L.). Its aim was to determine the most effective light exposure duration for enhancing mushroom growth and yield. Research Design: Using a completely randomized design (CRD), the study used four treatments: 8 hours of lighting (T1), 12 hours of lighting (T2), 16 hours of lighting (T3), and a control group that received natural light (T4). The study was conducted in Palayamanan (8° 27’ 5.3118" N and 126° 9’ 59.7739" E) area at North Eastern Mindanao State University’s -Tagbina Campus from July 2023 to November 2023. Results: Results from the study provided interesting insights into the indirect nature of the relationship between light exposure and mushroom development. The findings of the study indicate that the duration of light exposure significantly affects the growth and yield of white oyster mushrooms. Both mycelium growth (29.80 days) and fruiting body formation (7.83 days), as well as harvesting time (10.87 days), were improved by 12 hours of lighting, while the control group consistently showed poor performance. Conclusion: Based from the analysis, it is evident that 12 hours of lighting consistently performed very well, with the exception of a minor under-performance in the case of yield per harvest, suggesting that 12 hours might be the ideal duration. Hence, 16 hours of lighting also demonstrated some advantages in certain variables, indicating potential for further study.

Effects of Salicornia-supplemented wheat straw on the biological yield, amino and fatty acids of elm oyster mushroom, (Hypsizygus ulmarius Elm A)

The study examined the impact of Salicornia supplementation on the biological efficiency and biochemical properties of white Elm oyster mushrooms, Hypsizygus ulmarius. Four substrates were used to cultivate the mushrooms. Wheat straw was used as the main substrate and the Salicornia was used to partially replace the main substrate at the ratios of 5, 10, and 20% while 100% wheat straw was used as the control. The study found that the 20% Salicornia completed the mycelial run earlier (41 days), while the control treatment took the longest (45 days). The 5% Salicornia supplemented treatment and control treatment had the highest and lowest biological efficiencies (126 and 65%) respectively. The elemental concentration was undetectable for Copper (Cu), Lead (Pb), and Cadmium (Cd). The mushrooms from the control had the highest while those from the 20% treatment had the lowest (Zinc (Zn) levels (0.0115 ug/100 g) and 0.0078 ug/100 g). Conversely, Chromium (Cr) levels were highest and lowest in the 20% (0.0022 ug/100 g) and control treatments (0.0007 ug/100 g). Similarly, the total unsaturated fatty acids were highest in the control treatment (78%) and lowest in the 20% treatment (69%) while the opposite was true for the saturated fatty acids (22% and 31%). The mushrooms investigated in this study had higher essential amino acids (44–49%) compared to non-essential amino acids (17–20%). The results from this study suggest that Salicornia is a promising marine resource with the potential to enhance the health-promoting properties of oyster mushrooms.

Spray dried protein concentrates from white button and oyster mushrooms produced by ultrasound-assisted alkaline extraction and isoelectric precipitation.

In the present study, the optimization of ultrasound-assisted alkaline extraction (UAAE) and isoelectric precipitation (IEP) was applied to white button (WBM) and oyster (OYM) mushroom flours to produce functional spray dried mushroom protein concentrates. Solid-to-liquid ratio (5-15% w/v), ultrasound power (0-900 W) and type of acid [HCl or acetic acid (AcOH)] were evaluated for their effect on the extraction and protein yields from mushroom flours submitted to UAAE-IEP protein extraction. Prioritized conditions with maximized protein yield (5% w/v, 900 W, AcOH, for WBM; 5% w/v, 900 W, HCl for OYM) were used to produce spray dried protein concentrates from white button (WBM-PC) and oyster (OYM-PC) mushrooms with high solids recovery (62.3-65.8%). WBM-PC and OYM-PC had high protein content (5.19-5.81 g kg-1), in addition to remarkable foaming capacity (82.5-235.0%) and foam stability (7.0-162.5%), as well as antioxidant phenolics. Highly pH-dependent behavior was observed for solubility (> 90%, at pH 10) and emulsifying properties (emulsification activity index: > 50 m2 g-1, emulsion stability index: > 65%, at pH 10). UAAE-IEP followed by spray drying increased surface hydrophobicity and free sulfhydryl groups by up to 196.5% and 117.5%, respectively, which improved oil holding capacity (359.9-421.0%) and least gelation concentration (6.0-8.0%) of spray dried mushroom protein concentrates. Overall, the present study showed that optimized UAAE-IEP coupled with spray drying is an efficient strategy to produce novel mushroom protein concentrates with enhanced functional attributes for multiple food applications. © 2024 The Author(s).

Mycelial growth, yield and decomposition capability of white oyster mushroom (Pleurotus florida) grown in low-density polyethylene (LDPE) plastic and lignocellulosic wastes

White Oyster Mushroom (Pleurotus florida) is one of the domesticated mushrooms in the Philippines and known to grow in various biodegradable wastes. Low Density Polyethelene (LDPE) plastic is one of the most common non-biodegradable wastes in the environment which causes pollution. At present, biodegradation process is one of the ways to degrade plastics because of its non-polluting mechanism and cost-effectiveness. Thus, this study aimed to determine if P. florida could grow in LDPE plastic and facilitate its decomposition. Fourteen treatments were used in the study, laid out in Complete Randomized Design, and replicated thrice. The first four (4) treatments were composed of substrates with no LDPE plastics (rice straw, sawdust and cocopeat) while the rests were substrates with certain percentage of LDPE plastics. Observation was done for eight (8) weeks in the PUP Lopez Mushroom Laboratory and the data obtained was analyzed using ANOVA. Result shows that slight decomposition happened in LDPE plastic mixed with lingo-cellulosic wastes. Small spots or dark holes appear in the surface of LDPE plastics observed under microscope which is a sign of decomposition. In terms of mycelial ramification, fruiting bags with LDPE plastics were first to occupy the fruiting bag. There was also a decreased weight of the fruiting bags after 8 weeks. In terms of yield, substrates without LDPE plastics grew mushrooms with the highest weight. However, yield in sawdust and cocopeat substrates were not significantly different with the yield of mushrooms grown in substrates with LDPE plastics.

Effects of Consuming White Button and Oyster Mushrooms within a Healthy Mediterranean-Style Dietary Pattern on Changes in Subjective Indexes of Brain Health or Cognitive Function in Healthy Middle-Aged and Older Adults.

Limited research suggests mushroom consumption may improve indexes of brain health. Mushrooms contain bioactive compounds and antioxidants capable of crossing the blood-brain barrier and impacting vital neurological processes. We conducted a randomized controlled feeding trial assessing the effects of adopting a healthy U.S. Mediterranean-style dietary pattern (MED) with or without mushrooms on indexes of brain health and well-being. Sixty adults (aged 46 ± 12 y; BMI 28.3 ± 2.84 kg/m2; mean ± SD) without severe depression consumed a fully controlled MED diet with 84 g/d of mushrooms (4 d/week white button and 3 d/week oyster) or without (control with breadcrumbs) for 8 weeks. At baseline and post-intervention, surveys were used to evaluate anxiety, depression, mood, and well-being, and behavioral tests were used to evaluate cognition. Consumption of the MED diet, with or without mushrooms, increased (improved) self-reported vigor/activity (Time p = 0.026) and both behavioral measures of immediate memory (Time p < 0.05). Mixed effects were observed for other domains of neuropsychological function, and there were no changes in other measured indexes of brain health with the consumption of either MED diet. Adopting a healthy MED-style dietary pattern, with or without consuming white button and oyster mushrooms, may improve vigor/activity and immediate memory among middle-aged and older adults.

Effect of aqueous extraction method on total water-soluble polysaccharides content and phytochemical properties of white oyster mushroom (Pleurotus ostreatus)

Abstract White oyster mushroom (Pleurotus ostreatus) is an important raw material for nutraceuticals because it contains various bioactive substances, including polysaccharides, vitamins, phenolic acids, terpenoids, and sterols. P. ostreatus mushroom polysaccharides possess diverse biological activities (antioxidant, hyperglycemic effects, and immunomodulatory). The extraction process impacts the yield, affecting the biological function of natural active ingredients. In this study, aqueous extraction methods, i.e., ultrasonic-assisted extraction (UAE), microwave-assisted extraction (MAE), and kinetic-assisted hot extraction (KAHE), were applied to investigate the impact of extraction methods on polysaccharides crude extract from the fruiting bodies of P. ostreatus mushroom and their phytochemical properties. Water-soluble polysaccharides content, total polyphenolic content, total terpenoid content, and antioxidant level were analyzed using the spectrophotometric method by phenol-sulfuric acid, Follin-Ciocalteau’s reagent, vanillin-perchloric acid, and 1,2-diphenyl-2-picrylhydrazyl (DPPH) scavenging assay, respectively. After the extraction process, the morphological alterations on the surface of mushroom residues were observed using Scanning Electron Microscopy (SEM). The investigation has shown that aqueous extraction methods significantly affect the yields of polysaccharides crude extract and other phytochemical properties, i.e., total phenolic content, terpenoid content, and the DPPH free radical scavenging activity. The sample from MAE had the highest total water-soluble polysaccharide content (61,73±1,35% w/w DW) and the highest total phenolic content (3,44±0,75 %w/w DW). MAE method has the best potential and efficiency compared to UAE and KAHE for extracting polysaccharides while maintaining their phytochemical properties.

Effect of Differences in the Composition of Growing Media on the Growth of White Oyster Mushroom Mycelium (Pleurotus ostreatus)

The use of the main growth medium in the form of wood sawdust in mushroom domestication is still higher than that of other organic materials, even though its availability is limited, so efforts need to be made to find a growth medium composition that minimizes the percentage of sawdust use. The purpose of this study was to determine the comparison of treatment 1 (80% teak sawdust, 10% bran, 5% tapioca flour, and 5% agricultural lime) with treatment 2 (70% teak sawdust, 15% bran, 10% tapioca flour, and 5% agricultural lime) on the percentage of growth and mycelium growth of white oyster mushrooms. Composting of growing media was carried out for 5 days, then baglog making was carried out, after which the baglog was sterilized for 4 hours. After sterilization, the baglog was cooled and inoculated. After inoculation, the baglog is incubated to grow mycelium. Then, after 15 days, data collection and calculation were carried out. The parameters measured were the percentage of growth and mycelium growth of white oyster mushrooms in baglogs. Results showed that the percentage of growth and mycelial growth of white oyster mushrooms in treatment 1 is better than in treatment 2. Reducing the percentage of the main growing medium of teak sawdust and adding the percentage of additional growing media of bran and tapioca flour has a negative impact on the number of baglogs that grow mycelium (percentage of growth) and the growth of white oyster mushroom mycelium. This means that reducing the main media of teak sawdust and adding additional media is not the right growing media composition for domestication of white oyster mushrooms, so it cannot be used as an alternative growing media composition to reduce the use of wood sawdust.

Unlocking the growth potential: harnessing the power of synbiotics to enhance cultivation of Pleurotus spp.

The oyster mushroom (Pleurotus spp.) is one of the most widely cultivated mushroom species globally. The present study investigated the effect of synbiotics on the growth and quality of Pleurotus ostreatus and Pleurotus pulmonarius. Different synbiotics formulations were applied by spraying mushroom samples daily and measuring their growth parameters, yield, biological efficiency, proximate composition, mineral content, total phenolic content (TPC), and diphenyl-1-picryl-hydrazyl (DPPH) radical scavenging activity. Results demonstrated that the most significant yield of oyster mushrooms was harvested from synbiotics sprayed with inulin and Lactobacillus casei (56.92 g). Likewise, the highest biological efficiency obtained with a similar synbiotic was 12.65%. Combining inulin and L. casei was the most effective method of improving the mushrooms' growth performance and nutrient content in both samples. Furthermore, synbiotics that combined inulin and L. casei resulted in the highest TPC (20.550 mg gallic acid equivalent (GAE)/g dry extract (DE)) in white oyster mushrooms (P. ostreatus). In comparison, in grey mushroom (P. pulmonarius) the highest TPC was yielded by L. casei (1.098 mg GAE/g DE) followed by inulin and L. casei (1.079 mg GAE/g DE). The DPPH results indicated that the oyster mushroom could be an efficient antioxidant. The results revealed that applying synbiotics improved the mushrooms' quality by increasing their antioxidant capacity with higher amounts of phenolic compounds and offering better health benefits with the increased levels of mineral elements. Together, these studies demonstrated the potential of using synbiotics as a biofertilizer, which is helpful for mushroom cultivation; therefore, it might solve the challenge of inconsistent quality mushroom growers face.
