“Antimicrobial activity of rhizospheric bacteria of Curcuma longa (Turmeric) producing metabolites against human pathogens”
Journal Title: IOSR Journal of Pharmacy and Biological Sciences (IOSR-JPBS) - Year 2017, Vol 12, Issue 1
Abstract
The present study was carried out to explore the production of antibiotics from soil microbes of medicinal Plant Curcuma longa (Turmeric). Soil samples of the Curcuma longa rhizosphere regions were collected from the different region in Akola City, Western Vidharbh region of Maharashtra. The bacterial culture from the soil samples were collected by the serial dilution and spread plate technique. The total 16 culture have been isolated from the soil samples and out of total 16 only 3 have been characterized which are potent isolates. These 3 isolates are active against the selected pathogens, E. coli, P. aeruginosa and S.aureus. These samples were labelled as S1,S2 and S3. The characterized 3 cultures were identified as Bacillus megatherium, Pseudomonas fluroscenes and Globicitella sulfidifacein by using Bergey’s manual of systemic bacteriology. The Rhizospheric bacterial crude extract of Bacillus megatherium, Pseudomonas fluorescence, Globicatella sulfidifaciens were found to be more or less active against almost all tested pathogenic strains. Hence Curcuma longa can be employed as source of natural antimicrobials that can serve as an alternative to conventional medicines.It was concluded that the best activity have been shown by the Curcuma longa rhizospheric isolates (S2) which is of Pseudomonas fluorescens against all three human pathogenic organisms (E.coli , S.aureus , P.aeroginosa ). The activity of rhizospheric isolates was showing best results against S. aureus
