The biofloculant production potential of a consortium of Streptomyces and Brachybacterium species were evaluated. Optimum bioflocculant yields (g/L) and flocculation activities (%) were observed for the following preferred nutritional sources: glucose (56%; 2.78 ± 0.15 g/L), (NH4)2NO3 (53%; 2.81 ± 0.37 g/L) and CaSO4 · H2O (47%; 2.19 ± 0.13 g/L). A Plackett-Burman design revealed the critical f...

Given the lack of accurate parameter values in discrete element simulation sweet potato seedling mechanized recovery, a direct measurement and virtual calibration method was used to study Discrete Element Method (DEM) parameters broken stems leaves. The intrinsic parameters, collision recovery coefficient static friction seedlings were acquired by physical experiments. Different combinations de...

Exo-polysaccharides like dextran produced by Weissella sp. have a wide range of applications in the food, pharmaceutical and other industries. This biopolymer and its derivatives like iron dextran, clinical dextran are rapidly emerging as a new and industrially important products. Dextran a polymer of glucose is produced using sucrose rich media with nitrogen source. It also requires efficient ...
