Biocontrol effects of Bacillus velezensis and Bacillus subtilis against strawberry root rot caused by Neopestalotiopsis clavispora

mycolabadmin

Researchers isolated three beneficial bacteria (two Bacillus velezensis strains and one Bacillus subtilis strain) that effectively fight strawberry root rot disease. These bacteria work by both directly killing the disease-causing fungus and boosting the strawberry plant’s natural immune system. The bacteria can live inside the strawberry plant and soil, providing long-lasting protection. This offers farmers an eco-friendly alternative to chemical fungicides for protecting their strawberry crops.

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.

Actinomycetes isolated from rhizosphere of wild Coffea arabica L. showed strong biocontrol activities against coffee wilt disease

mycolabadmin

Researchers discovered that certain bacteria called actinomycetes, particularly a strain called MUA26, can effectively fight coffee wilt disease, a serious fungal infection that damages coffee plants. These beneficial bacteria produce natural compounds that kill the disease-causing fungus and were tested on coffee seedlings in a greenhouse, showing 83% effectiveness at preventing the disease. This discovery offers coffee farmers an organic alternative to chemical pesticides, which are expensive and harmful to the environment.

Potential Protective Role of Amphibian Skin Bacteria Against Water Mold Saprolegnia spp

mycolabadmin

This research discovered that frogs have protective bacteria on their skin that can fight against harmful water molds called Saprolegnia. Scientists tested bacteria from different frog populations and found that certain types, especially Bacillus bacteria, could prevent the mold from growing. However, the bacteria’s protective ability depends on environmental conditions—they work better in nutrient-poor environments similar to natural ponds. This finding suggests that maintaining healthy environmental conditions is important for frogs to naturally resist these dangerous fungal infections.

Identifying Key Pathogens and Effective Control Agents for Astragalus membranaceus var. mongholicus Root Rot

mycolabadmin

Astragalus (a valuable traditional Chinese herb) often develops root rot disease caused by harmful fungi. Researchers identified the specific fungi causing this disease and tested various chemical fungicides and beneficial bacteria to control it. Carbendazim fungicide and a biocontrol bacterium called KRS006 proved most effective, suggesting a combination approach could protect this important medicinal plant from disease.

Antifungal effect of soil Bacillus bacteria on pathogenic species of the fungal genera Aspergillus and Trichophyton

mycolabadmin

Scientists found that certain bacteria naturally occurring in soil can effectively kill harmful fungi that cause infections in humans. By isolating and testing different Bacillus bacteria species, researchers discovered that some were even more effective at inhibiting fungal growth than commonly used antifungal medications. This finding suggests a promising natural alternative to combat fungal infections, especially as many fungi are becoming resistant to traditional antifungal drugs.

Potential Protective Role of Amphibian Skin Bacteria Against Water Mold Saprolegnia spp.

mycolabadmin

Researchers discovered that bacteria living on frog skin can protect against a dangerous water mold called Saprolegnia that kills amphibian eggs and young tadpoles. They tested 196 different bacteria from frogs in Portugal and found that certain bacteria, especially Bacillus species, could stop the mold from growing. Interestingly, these bacteria worked best in clean water environments with fewer nutrients, similar to natural pond conditions, suggesting nature has built-in protections for amphibians.

Antifungal effect of soil Bacillus bacteria on pathogenic species of the fungal genera Aspergillus and Trichophyton

mycolabadmin

Researchers found that certain bacteria called Bacillus, naturally occurring in soil, can effectively kill dangerous fungi that cause infections in humans. These bacteria produce compounds that are as effective or more effective than standard antifungal medications. This discovery could lead to new treatments for fungal infections, especially as fungi increasingly develop resistance to current drugs.

Characterization of a bacterial strain T226 and its efficacy in controlling post-harvest citrus anthracnose

mycolabadmin

Researchers identified a beneficial bacterium called Lysobacter enzymogenes (strain T226) that effectively prevents citrus fruit rot caused by anthracnose fungus. This bacterium was isolated from soil and showed stable antimicrobial properties even after repeated culture transfers. When applied to citrus fruits, it reduced disease incidence by over 61% under natural storage conditions, performing better than the chemical fungicide prochloraz, making it a promising eco-friendly alternative for protecting stored citrus.

Identification of a Novel Pathogen of Peanut Root Rot, Ceratobasidium sp. AG-A, and the Potential of Selected Bacterial Biocontrol Agents

mycolabadmin

Scientists in China discovered a new fungal disease causing peanut root rot, identified as Ceratobasidium sp. AG-A. They tested three types of beneficial bacteria as natural pest control agents and found they effectively inhibited the disease-causing fungus while promoting peanut plant growth. These findings offer farmers an environmentally friendly alternative to chemical fungicides for managing this newly identified threat to peanut crops.
