Abstract:

Use of antibiotics and chemical compounds com to destroy the bacteria that caused the against antibiotics show resistance of the microorganisms. Therefore, in this  study,  examined of anti-bacterial extract with  ethanol, methanol, hexane,  chloroform  and hot water  brown algae  Sargassum glaucescensas.  The extractions against shrimp selective pathogen bacteria including Staphlilococus aureus, Vibrio harveyi, Escherichia coli, Bacillus cereus, Candida albicans, Aspergillus flavus  and  Fusarium solani were used by disk diffusion agar method. According to the results that the hot water extract in S. glaucesens none of the strains studied have antibiotic effects. Ethanolic extract in compared to other extracts showed better antibacterial activity (P<0.05). Therefor, V. harveyi  resistant  to extract n hexane of S. glaucesens, Sub-critical  to methanol and chloroform extract and sensitive to extract ethanol, but S. aureus sensitive to extracts n hexane, chloroform, methanol and ethanol, Also B. cereus sensitive to extract methanol and ethanol.
