Actinomycetes BBUU157 isolated from the vermicast of earthworms was identified to genus level using the 16S rRNA gene. The results showed that the nucleotide sequence was very similar to that of the genus Streptomyces. Growth of the organism under NaCl addition, production of plant growth-promoting agents, antibacterial and antifungal activities were tested. It could grow with 7% (w/v) NaCl and grew well in 800 and 1,000 mM NaCl solutions with a dry cell weight of 61.20 mg/ml and 65.70 mg/ml, respectively. There was no production of auxin hormones but it did produce a maximum siderophore when grown without NaCl. The orange zone size measured was 4.70 cm. It produced a maximum ACC deaminase at 72 hours in the absence of NaCl. It showed the actinomycetes's antagonistic activities against B. cereus, S. aureus and Penicillium sp. It was concluded that the actinomycetes isolate BBUU157 can promote plant growth under saline conditions and protect plants from phyto-pathogenic microorganisms. [ABSTRACT FROM AUTHOR] |
