ANTIMIKROBIAL ARIEN (HYPNEA CERVICORNIS) ASAL GILI KONDO TERHADAP BACILLUS SUBTILIS, STAPHYLOCOCCUS AUREUS & ESCHERICHIA COLI
ABSTRAK: To determine the
bioactivity of the species Hypnea cervicornis J.Agardh a test was carried out
by using crude extract and their fractions against a number of bioindicators
like Bacillus subtilis, Staphylococcus aureus and Escherichia coli. The bioactivity of H. cervicornis was tested
using Kirby-Bauer Method. The test
showed that both the crude extracts as well as the fractions, on crude extract
concentration 45 % - 55 %, methanol
fraction concentration 2,5 % - 12,5 % and n-hexane fraction concentration 1,25
% - 6,25 %, biologically active against the organisms used as bioindicators. As
these extract and fractions of H. cervicornis with its bioactivity could open
the opportunity for the use of H. cervicornis as an antibacterial bioactive
agents.
