Upregulation of ACC deaminase gene in Bacillus velezensis UTB96 improved yield and shelf Life of Agaricus bisporus

mycolabadmin

Researchers developed a way to improve button mushroom production using a beneficial bacterium treated with calcium chloride. This treatment boosts the bacteria’s ability to reduce ethylene, a natural plant hormone that causes mushrooms to age quickly. The treated mushrooms showed 23% higher yields and stayed fresh for at least three weeks in storage without browning, making them more appealing to consumers.

Dual benefits of Lysinibacillus xylanilyticus strain GIC41 in mitigating Pythium root rot and enhancing plant growth across cultivation systems

mycolabadmin

Scientists tested a bacteria strain called Lysinibacillus xylanilyticus (GIC41) to fight a destructive plant disease called Pythium root rot. In both soil and water-based growing systems, this bacteria significantly reduced disease symptoms in spinach and tomato plants while also making the plants grow bigger and stronger. The bacteria works by producing enzymes and possibly triggering the plant’s natural defenses, without directly poisoning the disease-causing pathogen.

Biocontrol of Cercospora leaf spot in sugar beet by a novel Bacillus velezensis KT27 strain: Enhanced antifungal activity and growth promotion in laboratory and field conditions

mycolabadmin

This research demonstrates that a beneficial bacteria called Bacillus velezensis KT27 can effectively control a common fungal disease in sugar beet crops. The bacteria fights the disease by producing natural antifungal compounds and can be further enhanced by exposure to inactivated fungal pathogens. Field trials showed the bacterial treatment provided disease protection almost as good as chemical fungicides while also promoting plant growth and increasing sugar beet yield by up to 15%.

Upregulation of ACC deaminase gene in Bacillus velezensis UTB96 improved yield and shelf Life of Agaricus bisporus

mycolabadmin

Researchers discovered that adding a beneficial bacteria called Bacillus velezensis UTB96 to mushroom growing substrates significantly improves both the amount of mushrooms produced and how long they stay fresh. When this bacteria was grown in a medium containing calcium chloride, it produced more of an enzyme called ACC deaminase that breaks down ethylene, a gas that causes mushrooms to age and brown. Mushrooms treated with this specially-prepared bacteria stayed fresher for three weeks in the refrigerator with minimal browning, and overall mushroom yield increased by up to 23%.
