Plasmid Coded Halotolerance in Mangrove Soil Bacteria
Nuzhat Ahmed, Fehmida Fasim, Zafar Nawaz and Fouad M. Qureshi

Abstract: Increasing salinity in the soil and irrigation water is a global concern of paramount importance especially to Pakistan. Isolation was carried out from soil samples of Mangrove area near `REHRI`, two isolates CMG350 (Staphylococcus saprophyticus) and CMG351 (Pseudomonas paucimobilis) were selected for further studies. Character halotolerance in both the isolates was plasmid born, as cured derivatives lost the character. Maximum accumulation of Na+ i.e., 12.5% was observed by CMG351 whereas 9.8% was observed by CMG350. Halotolerance was found associated with proteins encoded by plasmids.
