A polyphasic approach was applied to characterize 35 G. diazotrophicus isolates obtained from sugarcane varieties cultivated in Brazil. The isolates were analyzed by phenotypic (use of different carbon sources) and genotypic tests (ARDRA and RISA-RFLP techniques). Variability among the isolates was observed in relation to the carbon source use preference. Glucose and sucrose were used by all is...

Endophytes are known to improve plant growth using a multitude of mechanisms. Bacteria use variety mechanisms penetrate and reside in host. Producing hydrolytic enzymes is one these which hydrolyses the cell wall components cells helping bacteria enter through root hairs lateral roots. The present study focused on production enzyme by endophytic isolated from Vigna radiata Cajanus cajan. Out fo...

The detection of Virulence factors of Aeromonas spp. is a key component in determining potential pathogenicity because these factors act Multifuntionally and Multifactorially. In this study, totally 50 carp fish samples were collected, Among these, 8 samples were found to be positive for Aeromonas hydrophila and 13 were found to be positive for Aeromonas salmonicida. Antibiotic resistant patter...

-The disposal of toxic heavy metals such as arsenic posed high risk to the environment. Arsenite [As(III)], a reduced form of arsenic, is more toxic and mobile than arsenate [As(V)]. The aim of this work was to isolate arsenic-tolerant bacteria from contaminated soil collected from various industrial landfills of Gujarat, India. This study explores the potential of the amplified ribosomal DNA r...
