Isolation and Identification of Bacteria from the Rhizoplane of Rice
This study was conducted to characterize bacterial diversity in the rhizoplane of rice. Soil samples were collected in sterile Petri plates from the rhizoplane of different rice varieties grown in the Net house. Samples were analyzed for their bacterial content following colony morphology, microscopic and biochemical characters. Bacterial density recorded was in the range of 3.51 x 104 - 2.63 x 106 organisms per gram of soil. The isolated microbes were represented by a mixed population of five species (Bacillus sp., Staphylococcus sp., Streptococcus sp., Pseudomonas sp., and Escherichia coli). This study revealed that the bacterial population in the rhizoplane of rice varies significantly which may have an impact on the plant roots for their tolerance to stress.
