| Abstract | Microalgae contain high levels of proteins, lipids,carbohydratesand other bioactive metabolites with direct relevance to aquaculture. This investigation was done to assess the bioactive propertiesanddescribe the neutraceuticaland pharmacological benefitsof a green microalga, Chlorella minutissima(Chm1). The alga has a total phenolic content of 30.94ฑ0.06 mg GAEg-1. Relative antioxidant efficiency showed that C. minutissimaexerted potent ABTS scavenging activity and high ability of reducing copper ions in a concentration-dependent manner with IC50valuesof 48.13?g GAEml-1and 13.90 ?g GAEml-1, respectively.Evaluation of antibacterial activities using microtiter plate dilution assay revealed that C. minutissimashowed strong activity against Aeromonas hydrophila with a minimum inhibitory concentration (MIC) of 125 ?g ml-1. The algal extract is alsoeffective against Vibrio cholerae, Vibrio parahaemolyticusand Staphylococcus aureusin each casewith MIC value of 250 ?g ml-1. Also, C. minutissimaextract was able to inhibitthe growth of Pseudomonas fluorescenswithMIC value of 500 ?g ml-1. Proximate composition of the dried microalga showed that C. minutissimaconsistsofhigh protein, ash and crude fat content with values of 42.61ฑ0.11%, 17.79ฑ0.04% and 11.70 ฑ0.01%,respectively. The results show that C. minutissimais an excellent candidate organism as a potential source of chemical compounds important for feed formulation and disease control in aquaculture. |
