Optimization of protease production by Bacillus cereus HMRSC30 for simultaneous extraction of chitin from shrimp shell with value-added recovered products.

Chitin extraction from shrimp shell powder (SSP) using protease-producing microbes is an attractive approach for valorizing shrimp shell waste because it is simple and environmentally friendly. In this study, the protease production and chitin extraction from SSP by Bacillus cereus HMRSC30 were simultaneously optimized using statistical approaches. As a result, fermentation in medium composed of 30 g/L SSP, 0.

Optimization of glutaminase-free L-asparaginase production using mangrove endophytic B27.

The mangrove, , an essential source of endophytic bacteria, was investigated for its ability to produce glutaminase-free L-asparaginase. The study aimed to obtain glutaminase-free L-asparaginase-producing endophytic bacteria from the mangrove and to optimize enzyme production. The screening of L-asparaginase-producing bacteria used modified M9 medium.

Autochthonous Acid-Producing Bacteria from Catfish ( sp.) with Antibacterial Activity against Selected Fish Pathogens: A Preliminary Study.

In this study, the application of an autochthonous microorganism as probiotic on catfish ( sp.) was scarcely reported. This study aimed to obtain probiotic candidates from the digestive tract (intestinal and gastric) of catfish.

Antioxidant and cytotoxic activity of Acanthus ilicifolius flower.

Objective: To investigate the antioxidant and cytotoxic activity of the flower of Acanthus ilicifolius (A. ilicifolius).

Methods: Antioxidant activity was determined as antiradical efficiency with diphenyl picrylhydrazil (DPPH) method and cytotoxic assay was undertaken using brine shrimp lethal toxicity test.
