Impact of Volatile Organic Compounds on the Growth of Aspergillus flavus and Related Aflatoxin B1 Production: A Review

mycolabadmin

Aspergillus flavus is a dangerous fungus that produces aflatoxin B1, a poison that can cause serious diseases and survives even when food is heated. Scientists have discovered that certain smelly chemicals called volatile organic compounds, produced by other organisms or plants, can stop this fungus from growing and making its toxin. This research suggests these natural chemicals could be used to protect our crops and food supply from contamination.

Bacteria from the Amphibian Skin Inhibit the Growth of Phytopathogenic Fungi and Control Postharvest Rots

mycolabadmin

Researchers discovered that bacteria living on frog skin can effectively prevent fungal diseases that rot fruits after harvest. These bacteria work by producing toxic compounds and releasing protective gases that stop fungi like green mold from growing. When applied to citrus, tomatoes, and blueberries, the bacteria significantly reduced fruit rot, offering an eco-friendly alternative to chemical fungicides for food preservation.

Metabolite Profiles and Biological Activities of Different Phenotypes of Beech Mushrooms (Hypsizygus marmoreus)

mycolabadmin

This study compared white and brown varieties of beech mushrooms, which are popular edible mushrooms in South Korea. Brown beech mushrooms were found to have higher levels of beneficial compounds called phenolics, which give them a more bitter taste and brown color. The research showed that brown mushrooms have stronger health-promoting properties, including better abilities to fight bacteria, reduce inflammation, and combat oxidative stress, making them potentially more valuable as functional foods for health and nutrition.

Effects and formula optimization of Rosa roxbunghii pomace substrate on the yield and volatile flavor compounds of Lentinula edodes

mycolabadmin

Researchers discovered that using Rosa roxbunghii fruit waste as 30% of the growing medium for shiitake mushrooms produces better yields and more flavorful mushrooms compared to traditional sawdust-based methods. This sustainable approach solves a waste disposal problem while making mushrooms taste better, with higher levels of umami-contributing compounds. The findings could help local farmers reduce costs and improve mushroom quality while managing agricultural waste responsibly.

A comparison of the performance of bacterial biofilters and fungal–bacterial coupled biofilters in BTEp-X removal

mycolabadmin

Researchers compared two types of biofilters for cleaning polluted air from petrochemical plants. Fungal-bacterial biofilters significantly outperformed bacterial-only biofilters at removing harmful aromatic chemicals. The combined system recovered faster after interruptions and remained stable longer during continuous operation, making it more practical for industrial applications.

Inhibitory and synergistic effects of volatile organic compounds from bat caves against Pseudogymnoascus destructans in vitro

mycolabadmin

Researchers discovered that two natural compounds found in bat cave environments—isovaleric acid and ethyl methyl carbonate—can effectively kill the fungus that causes white-nose syndrome in bats. When used together, these compounds work even better than alone, disrupting the fungus’s cell membranes, causing it to produce too many reactive molecules (free radicals), and triggering cell death. This discovery offers hope for developing new treatments to protect bat populations that have been devastated by this disease in North America.

Analysis of Volatile Organic Compounds and Comparison of Heat Resistance Related Gene Expression in Pleurotus ostreatus Under Heat Stress

mycolabadmin

This study examined how oyster mushrooms respond to high temperatures at different growth stages. Researchers found that young mycelium and mature fruiting bodies use different strategies to survive heat stress, which affects the flavor compounds they produce. Mycelium produces more of certain volatile compounds under heat stress, while fruiting bodies actually lose their characteristic mushroom flavor compound called 1-Octen-3-ol.

Biocontrol of Cheese Spoilage Moulds Using Native Yeasts

mycolabadmin

This research explores using naturally occurring yeasts found in cheese to prevent mould spoilage, offering a chemical-free alternative to current preservatives. Scientists tested 84 yeast strains and identified the most promising ones that can inhibit growth of three common spoilage moulds through different mechanisms like enzyme production and nutrient competition. Two yeast strains, Geotrichum candidum GC663 and Pichia jadinii PJ433, showed particularly strong potential for protecting cheese quality and extending shelf life when tested in actual cheese.

Bacterial community shifts in Fusarium-induced avocado root rot and the antagonistic potential of Bacillus siamensis NB92

mycolabadmin

Avocado plants are threatened by a fungal disease called root rot that damages roots and reduces fruit production. Researchers discovered that when avocado roots become diseased, the beneficial bacteria in the soil around the roots decrease significantly. They isolated a beneficial bacterium called Bacillus siamensis NB92 from healthy avocado soil that can fight against the disease-causing fungus by producing special compounds. When applied to diseased soil, this bacterium reduced the fungal pathogen and protected avocado stems from damage, offering a natural alternative to chemical treatments.

The biocontrol potential of endophyte Bacillus velezensis to reduce post-harvest tomato infection caused by Rhizopus microsporus

mycolabadmin

Researchers tested a naturally occurring bacteria called Bacillus velezensis as a safe alternative to chemical fungicides for protecting tomatoes from rot-causing mold. The bacteria produces special compounds that can kill or slow down the growth of Rhizopus microsporus, a fungus that commonly spoils tomatoes after harvest. While the results show promise, the effectiveness varied depending on which specific strain of bacteria and mold was used, suggesting more research is needed to fine-tune the approach.
