Isolation and Characterization of Halophilic Bacteria from Salinity Soil of Shatkhira, Bangladesh (original) (raw)

2020, Journal of advances in microbiology

Aim: The aim of this study was undertaken for the isolation and molecular characterization of the halophilic bacteria from salt affected soils. Place and Duration of Study: This study was conducted on the salinity affected area in Ramzan Nagor under Shamnagor Upazilla of Shatkhira District, Bangladesh. The collection of soil sample, isolation of halophilic bacteria and subsequent experiments were done from May to December 2018. Methodology: Salt affected soil could be good source of halophilic bacteria as it contain high amount of salt. Hence, one gram of salt affected soil sample which was containing high amount of salt was suspended to 100 ml sterile distilled water and one ml of sample from the top of the suspension were taken in to 250 ml Erlenmeyer flaks containing 100 ml of mineral salts (MS) medium. The primary enrichment was incubated for several days at 37C with shaking at 120 rpm (revolution per minute) on an orbital shaker. Cultures which were found to be turbid after a period of up to 4 days were used as inocula in subsequent experiments. Results: Four halophilic bacterial strains viz. Bacillus sp. strain 8-15, Enterobacter sp. strain LCR75, Acinetobacter sp. strain 407 and Acinetobacter junii strain F27 were isolated from the saline Original Research Article
