CHEMICAL COMPOSITION AND IN VITRO ANALYSIS OF ANTIBACTERIAL ACTIVITY OF ACUTODESMUS DIMORPHUS (TURPIN) P.M. TSARENKO (SCENEDESMACEAE, CHLOROPHYTA)

Objective: Green microalgae are fast growing organisms and known to have diverse bioactive compounds biomolecules. The chemical composition antibacterial activities of a green microalga, A. dimorphus BIOTECH 4039 were studied. 
 Material Method: Dried algal biomass was subjected proximate elemental analysis. Methanolic extract used determine the total phenolic content activity microalga. against medically important bacterial pathogens done using modified Kirby-Bauer inhibition assay. Results Discussion: Acutodesmus contained high amounts protein, ash, lipid with percent 43.19 ± 0.13, 26.92 0.01, 14.17 0.04, respectively. nutrient observed be in decreasing order Ca > Mg K Mn Na Fe Zn Pb Cu Cd >Cr. In addition, has TPC 5.34 0.09 mg GAE/g. Potent Methicillin-Resistant Staphylococcus aureus, S. epidermidis, penicillin acylase-producing Bacillus cereus zones 15.1 0.3 mm, 13.5 0.1 6.82 0.7 study shows use as good alternative source microelements that can industrial pharmaceutical application.
