Optimized production of Serratia marcescens B742 mutants for preparing chitin from shrimp shells powders.

To improve the deproteinization (DP) efficacy of shrimp shell powders (SSP) for preparing chitin, Serratia marcescens B742 mutants were prepared using 2% diethyl sulfate (DES), UV-irradiation, and/or microwave heating treatments. Both single-stage and multi-stage mutations were investigated for optimizing S. marcescens B742 mutation conditions. Under the optimized mutation conditions (2% DES tr...

Serratia marcescens B4A Chitinase Product Optimization Using Taguchi Approach

Chitinase production by newly isolated Serratia marcescens B4A was optimized following Taguchi’sarray methods. Twenty-three bacterial isolates were screened from shrimp culture ponds in the South ofIran. A chitinase-producing bacterium was isolated based on it’s ability to utilize chitin as the sole carbonsource. The isolate designated as B4A, was identified as Serratia marces...

Chitinase Isolated from Water and Soil Bacteria in Shrimp farming Ponds

 Chitinases have received attention because of their wide applications in the medicine, biotechnology, agriculture, waste management and industrial applications such as food quality enhancer and biopesticide. Excessive use of insecticides has led to several problems related to pollution and environmental degradation. In this study, isolation and identification of native bacterial strains with c...
