Abstract

The concept of biological control for health maintenance has received worldwide attention during the last few decades. Therefore, the main objective of this work was to look for active substances that could be used as antibacterial agents. To achieve this target different extracts (Methanol, Petroleum ether, Dichloromethan, Ethyl acetate) fromAnabaena oryzae,were examined. The algal extracts were tested in vitro for itsantibacterial effects against three  Gram +ve and Gram -ve bacteria (Escherichia coli, Bacillus cereus,Klebsiella pneumonia) using Agar well diffusion method and concentrations from 50 mg up to 150 mg were taken tested bacteria showed inhibition in growth by these  extracts.
Conclusively, the results obtained in the present investigation clearly suggest that the production of pharmacologically products from Aphanocapsasp, could represent a viable and environmentally friendly alternative to reduce the use of synthetic chemicals because of their unintended side effects for the control of pathogenic microorganisms.
