Bacillus Subtilis
Bacillus Subtilis Fungicides in the Past
B. subtilis is a Gram - positivist bacterium that has played a important role in the story of fungicides .
The use of B. subtilis as a fungicide dates back several decennary . Its first record use can be trace back to the forties .
In the former years , B. subtilis was mostly used in agricultural and horticultural practices to combat fungal diseases that affected crops and plants .
Farmers and gardeners recognized its potential as a natural and in force alternative to celluloid chemical fungicides .
Over sentence , research and advancements in ergonomics have further heighten our understanding of B. subtilis and its fungicidal prop , so today , we have many refined formulation and software method from which to choose .
How Does B. Subtilis Prevent or Kill Pathogens & Fungal Growth?
The various striving of B. subtilis bring on over two dozen different types of antibiotic to protect plants . These antibiotics are of a peculiar form have sex as lipopeptides . In Latin , lipo means lipide or rich .
Peptide refers to amino Elvis that are link up together by peptide bonds . These short amino acid chains are protein - building blocks .
Lipopeptides often have antiviral , antimicrobial , and immunomodulatory power and are also effective in breaking down fungous growth .
These special antibiotic break down the membranes of fungous jail cell ( which consist of lipide ) . This results in the death of the fungus , as excuse in this TV .
