The use of this beneficial bacterium in agriculture and related areas brings down the dependency on chemical inputs and can save the environment in the era of climate change. polymyxa are reported for biofertilizer, biopesticide, biofuel, bioremediation application which shows the biotechnological potential of this bacterium in sustainable agriculture. However, the first two groups are often reported. polymyxa are grouped into four classes, viz., fusaricidin, polymyxin, tridecaptins, and paenilin (Lantibiotics). The molecular mass of these antimicrobial peptides is in the range of 800–3500 Da. ![]() polymyxa protect the host plant against bacterial and fungal pathogens infestation through nonribosomal synthesis and extracellular secretion of small molecular weight peptides called lipopeptides. polymyxa possesses the plant growth-promoting (PGP) traits, which include nitrogen fixation, mineral solubilization (phosphorus, potash, zinc etc.), IAA, siderophore, and hydrolytic enzymes production (chitinase, cellulase, amylase, pectinase, lignocellulolytic enzymes, etc.). It is often associated within the host plant as an endophyte and helps the plant through biofortification of nutrients and induced systemic resistance against pathogen attack. ![]() Paenibacillus polymyxa is a gram-positive, rod-shaped, endospore-forming, facultative anaerobic soil bacterium which performs important ecological functions, especially organic matter decomposition, nutrient recycling, and antagonism against harmful pathogens in agricultural ecosystem.
