The gene for beta-amylase was isolated from Bacillus polymyxa by molecular cloning in B. subtilis. B. subtilis cells containing this gene express and secrete an amylase which resembles the B. polymyxa beta-amylase and barley beta-amylase in terms of the products it generates during carbohydrate hydrolysis. Starch hydrolysis with this beta-amylase produces maltose, not glucose, whereas maltotrio...

The valorization of fruit and vegetable residues (such as carrot discard) their microbial conversion into 2,3-butanediol (BDO) can be considered a very interesting way to reduce food waste sustainably originate high value-added products. This work analyzes the discard feedstock for production by Paenibacillus polymyxa DSM 365. influences stirring presence tryptone (nitrogen source) are studied....
