Transforming Tomato Industry By-Products into Antifungal Peptides Through Enzymatic Hydrolysis

mycolabadmin

Researchers have found a way to turn tomato processing waste into useful antifungal compounds. By breaking down tomato seed proteins using enzymes, they created peptides that can prevent harmful fungi like Fusarium from growing on crops. This discovery helps reduce food waste while providing a natural alternative to chemical pesticides for protecting tomato and grain crops.

Scientists isolated a beneficial bacterium called Streptomyces roietensis from soil that effectively fights gray mold, a serious fungal disease affecting crops worldwide. They identified the strain and optimized growing conditions to maximize production of antifungal compounds, achieving 93% effectiveness against gray mold. This discovery offers a natural, environmentally-friendly alternative to chemical fungicides for protecting agricultural crops, potentially reducing crop losses and environmental pollution.

Nature-Inspired Biphenyls and Diphenyl Ethers: Design, Synthesis, and Biological Evaluation

Researchers synthesized compounds inspired by naturally occurring substances found in brown algae called phlorotannins. These synthetic compounds were tested against fungi that damage rice crops and other plants. Some methylated versions showed promise in slowing fungal growth, suggesting they could potentially be developed into new natural fungicides. However, the compounds were not effective against bacteria, indicating more research is needed.

Antifungal effects of metabolites from Arthrinium sp. 2–65 and identification of main active ingredients

Scientists discovered that a fungus called Arthrinium sp. 2–65, found living inside a wild plant called Thymus mongolicus, produces two special compounds that can kill the fungus responsible for grey mould disease. Grey mould is a major problem for farmers worldwide, damaging crops like tomatoes, grapes, and strawberries. These newly identified compounds were tested and showed excellent effectiveness against the disease, offering a promising natural alternative to chemical pesticides that have become less effective due to resistance and environmental concerns.

Bacillus velezensis CNPMS-22 as biocontrol agent of pathogenic fungi and plant growth promoter

A bacterial strain called Bacillus velezensis CNPMS-22 shows promise as a natural pest control agent for crops. When applied to maize seeds, it reduced fungal diseases and increased plant productivity as effectively as chemical fungicides. The bacteria produces natural compounds that kill harmful fungi while also promoting plant growth, offering a safer, more environmentally friendly alternative to synthetic chemicals.
