Screening for antibacterial and antifungal activities in some marine algae from the Fujian coast of China with three different solvents
摘要
Abstract
Three different solvents viz ethanol
acetone and methanol-toluene (3:1) were used to extract antibiotics from 23 species of marine algae belonging to the Chlorophyta
Phaeophyta and Rhodophyta. Their crude extracts were tested for antibacterial and antifungal activities. Among them
the ethanol extract showed the strongest activity against the bacteria and fungi tested. Four species of the Rhodophyta (Laurencia okamurai
Dasya scoparia
Grateloupia filicina andplocamium telfairiae) showed a wide spectrum of antibacterial activity. Every solvent extract from the four species was active against all the bacteria tested. The test bacteriumPseudomonas solancearum and the fungusPenicilium citrinum were most sensitive to the extracts of marine algae. In general
the extracts of seaweeds inhibited bacteria more strongly than fungi and species of the Rhodophyta showed the greatest activity against the bacteria and fungi tested.
