Isolation and Identification of Drought-tolerant Bacteria from Xerophtes

doi:10.7506/spkx1002-6630-201205028

Abstract

Abstract: Drought-tolerant bacteria were isolated and identified in this paper. One hundred and forty two bacterial strains were isolated from the typical drought-tolerant plants. Through adding polyglycol 6000 (PEG6000) to the fluid nutrient medium for decreasing osmotic potential, the drought tolerance of endophytic bacteria were analyzed. One of these strains, PB14, has the capability of drought resistance up to 60 g/100 mL PEG6000. This strain was identified as Bacillus cereus based on morphological and biochemical experiments as well as 16S rDNA sequence analysis.

Key words: drought tolerance, endophytic bacteria, identification, Bacillus cereus
