Patulin Biodegradation by Rhodosporidiobolus ruineniae and Meyerozyma guilliermondii Isolated From Fruits

mycolabadmin

Patulin is a dangerous toxin produced by molds that grow on apples and peaches, posing serious health risks to consumers. Researchers isolated two yeast species from fruits that can effectively break down patulin into a less toxic compound called (E)-ascladiol. The yeasts work by using enzymes inside their cells to degrade the toxin, and this biological approach could be used to safely remove patulin from contaminated fruits and fruit products.

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.

The Function of Chitinases CmCH1 and CmCH10 in the Interaction of Coniothyrium minitans and Sclerotinia sclerotiorum

mycolabadmin

Scientists studied two enzyme genes in a fungus that eats other harmful fungi. When they removed one gene at a time, the fungus still worked fine. But when they removed both genes together, the fungus grew slower and couldn’t attack its target fungus as effectively. This shows that these genes work together as a team to help the fungus do its job as a natural pest control agent.

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.

Microbial-mediated induced resistance: interactive effects for improving crop health

mycolabadmin

This research explores how beneficial microbes like Trichoderma fungi and Bacillus bacteria can help plants naturally defend themselves against diseases. These microbes trigger the plant’s built-in immune system through chemical signals and molecular processes similar to how our immune system responds to threats. The approach offers an eco-friendly alternative to chemical pesticides for protecting crops, though effectiveness varies depending on environmental conditions.

Bioprospecting and mechanistic insights of Trichoderma spp. for suppression of Ganoderma-induced basal stem rot in oil palm

mycolabadmin

Scientists discovered that a fungus called Trichoderma afroharzianum can effectively fight a serious disease in oil palm trees caused by another fungus, Ganoderma. This beneficial fungus works by producing natural chemicals and enzymes that kill the harmful pathogen and also helps the plants grow better. The research shows this could be used as an eco-friendly alternative to chemical pesticides for protecting oil palm plantations, especially as climate changes and farming conditions vary.

Sustainable Innovations in Food Microbiology: Fermentation, Biocontrol, and Functional Foods

mycolabadmin

This review explores how microorganisms can make food production more sustainable and healthier. It discusses traditional fermented foods like yogurt and sauerkraut, modern biotechnology techniques to reduce food waste and create natural preservatives, and special food ingredients with beneficial bacteria that support digestive and mental health. The paper shows how applying microbial science could help address global food challenges while meeting consumer demands for natural, safe, and healthy products.

The Biological Product Agricultural Jiaosu Enhances Tomato Resistance to Botrytis cinerea

mycolabadmin

Agricultural Jiaosu is a fermented product made from plant waste that effectively controls gray mold disease in tomatoes through two mechanisms: it directly kills the fungus with organic acids, and it strengthens the plant’s natural defenses. When applied as a spray to tomato leaves once a week, it reduced disease by 55%, made plants grow taller and stronger, and boosted the plants’ protective enzymes. This natural alternative to chemical fungicides offers a sustainable and safe way to protect tomato crops while maintaining environmental health.

Cystobacter fuscus HM-E: a novel biocontrol agent against cotton Verticillium wilt

mycolabadmin

A naturally occurring bacterium called Cystobacter fuscus shows great promise as a biological control agent against a serious fungal disease that damages cotton plants. When formulated as a solid product and applied to soil, this microorganism was able to prevent disease in over 70% of cotton plants tested in greenhouse experiments. The bacteria work by attacking and breaking down the fungal pathogen while also promoting healthier plant growth, offering farmers an environmentally friendly alternative to chemical fungicides.

Characterization of Two Potential Biocontrol Bacillus Strains Against Maize Stalk Rot

mycolabadmin

Scientists discovered two beneficial bacteria, Bacillus subtilis and Bacillus siamensis, that can protect maize plants from a serious fungal disease called stalk rot. These bacteria work in two ways: they directly kill the fungus and they promote healthy plant growth. By analyzing the bacteria’s genetic makeup, researchers found that they produce multiple natural antibiotic compounds that explain their powerful disease-fighting abilities. This research suggests these bacteria could be used as a natural, environmentally-friendly alternative to chemical fungicides for protecting crops.
