“…These EPSs have been widely used within bioindustries as foods [58], medicines [59] and cosmetics [60] as well as for the removal of metal ions from waste water [61,62] and mineral processing [63], because the production cost of microbial EPS is lower than that of algal or plant polysaccharides [64]. Additionally, bacterial EPS is non-toxic, biodegradable and environmentally friendly [65].…”

Microbial diversity is a major resource for biotechnological products and processes. Bacteria are the most dominant group of this diversity which produce a wide range of products of industrial signifi cance. Paenibacillus polymyxa (formerly Bacillus polymyxa), a non pathogenic and endospore-forming Bacillus, is one of the most industrially signifi cant facultative anaerobic bacterium. It occurs naturally in soil, rhizosphere and roots of crop plants and in marine sediments. During the last two decades, there has been a growing interest for their ecological and biotechnological importance, despite their limited genomic information. P. polymyxa has a wide range of properties, including nitrogen fi xation, plant growth promotion, soil phosphorus solubilisation and production of exopolysaccharides, hydrolytic enzymes, antibiotics, cytokinin. It also helps in biofl occulation and in the enhancement of soil porosity. In addition, it is known to produce optically active 2,3-butanediol (BDL), a potentially valuable chemical compound from a variety of carbohydrates. The present review article aims to provide an overview of the various roles that these microorganisms play in the environment and their biotechnological potential.

“…5. All samples exhibited a broad stretching intense characteristic peak at around 3429 cm −1 for the hydroxyl group, and a weak C-H band at around 2929 cm −1 [19]. The band at 1627-1651 cm −1 was due to the bound water [20].…”
