Abstract

Streptomyces, the predominant genus of Actinobacteria, is a group of bacteria that is most frequently isolated from soil. The isolation and biochemical characterization of Streptomyces spp. are the main objectives of this work. In the present study, rice rhizospheric soil samples were collected from different rice-growing areas of Odisha. A total of eight morphologically distinct actinomycetes were isolated and identified as Streptomyces spp. through a series of biochemical tests viz., gram staining, catalase test, gelatin hydrolysis, citrate utilization test, starch hydrolysis, indole test, HCN test, casein hydrolysis and cellulase test. Biochemical test results confirmed that all the eight isolates belong to the genus Streptomyces

Keywords

Streptomyces spp., biochemical test, characterization, rice

Conclusion

This study aimed to investigate the potential of Streptomyces species associated with rice as rhizobacteria that promote plant growth for enhancing agricultural productivity and plant disease resistance. The isolates were subjected to biochemical characterization. The isolates were also tested for the production of indole acetic acid and other biocontrol properties such as hydrogen cyanide production. The findings revealed that all eight isolates were found to belong to the genus Streptomyces. At the field level, the potential of these isolates could be thoroughly examined
