Preliminary Phytochemical Screening of Various Solvent Extracts of Caulerpa Racemosa and its Antibacterial Activity Against Bacteria Isolated From Spoiled Food Idly

Abstract

 Isolates from contaminated idly arescreened for antibacterial activity. In this content of the antibacterial activity,Caulerpa racemosa (Green algae) produce secondary metabolites against the pathogenic microbes have been used extensively in drug and pharmaceutical industry, agriculture and biodeterioration process.  Many studies show that Caulerpa racemosa naturally had the potency of antibacterial activity againstfood contaminating pathogen. In the present study, four bacterial strains were isolated from the spoiled idly. These strains were characterized by subjecting to various biochemical tests results the isolated strains are Staphylococcus,Pseudomonas, Klebsiella and Bacillus Species. When Compared to Aqueous Extract of C.racemosa, the acetone, petroleum ether, chloroform extract of Caulerpa racemosa shows growth inhibition of the isolated strains from spoiled food. FT-IR analysis peak level shows various functional compounds such as primary, secondary amines and amides, aliphatic amines, alkenes and aromatic compounds will inhibit bacterial growth.
