ABSTRACT
Marine bacteria were isolated from seawater was collected from different coastal areas of the Tamilnadu Sea. The antimicrobial activities of these bacteria were investigated. Ethyl acetate extracts of marine bacterial fermentation were screened for antimicrobial activities using the method of agar diffusion. The results showed that 25 strains of the isolates have antimicrobial activity. The proportion of active bacteria associated with isolated from seawater. The active marine bacteria were assigned to the genera Alteromonas, Pseudomonas, Bacillus and Marinobacter. The TLC autobiographic overlay assay implied that the antimicrobial metabolites produced by four strains with wide antimicrobial spectrum were different. These marine bacteria were expected to be potential resources of natural antibiotic products. It can be concluded that isolation of Marine bacterial samples can offer a numbers of microbial strains for sources of new biomolecules from Marine sources.
ABSTRACT
Hydnocarpus alpina WIGHT. is a evergreen forest plant. It is an endemic plant to western ghats of India. Several local names are available based on distribution among the state in india that is Torathi (kanada), Maravetti (Malayalam), attuchankalai (tamil), kastel (hindi). This tree has very appreciated value in the aspect of medicine. It has anti-larvicidal, anti-feedant, anti-microbial and etc. It has the medicinal properties due to the presence of its significant chemical constituents. In this paper revealed that the IR spectrum and chemical constituents which are present in different solvents (chloroform, pet.ether, ethanol, water).
