TL;DR: It could be stated that productive medium supplemented with 2% potato starchy waste as a low price substrate could be more favorable than basal medium containing 1% starch for amylases production in submerged fermentation, as it increased α, β and γ amylase activity by 1.98, 7.69 and 12-fold than that produced in basal medium (control), respectively.

Abstract: Effect of some nutritional and environmental factors on g ro wt h and cellulase production 3 by Bacillus alcalophilus S39 and Bacillus amyloliquefaciens C2 was inves tigated. Results indicated t h a t 1% carboxymethylcellulose (CMC) and 0.7% yeas t extract were mos t effective as the carbon an d nitro g e n s o urces respectively. Initial pH 7 and 3% inoculum s ize found to be optimal for growth and cellu la se production. Incubation temperature at 30 and 45oC achieved the highes t activity of cellulase 3 for Bacillus alcalophilus S39 and Bacillus amyloliquefaciens C2 respectively, and the suitable shaking rate was 150 and 200 rpm.

TL;DR: In this article, a number of 26 fungal cultures were isolated from different phosphatic sources, including phosphate fertilizers and rock phosphate, and tested for heavy metals biosorption on solid medium supplemented with different metal ions at concentration of 50ppm.

TL;DR: The present study aimed at developing a strategy to improve the volumetric production of PHAs by Pseudomonas fluorescens S48 using waste frying oil (WFO) as the sole carbon source to attain high cell density and high biopolymer productivity.

TL;DR: In this paper, three types of Kombucha fermented tea, rice, and barley were produced in order to study their changes of biological and chemical parameters, and the results revealed that the preservation method using heat treatment (at 76 and 100°C for 10min) was not successful, resulting in a decrease in antioxidant amounts to 71.42% and total phenolic compounds to 40.22% and 45.69% respectively.
