Kappaphycus alvarezii one of the red seaweed species that rapidly demanded for its
kappa-carrageenan. The industrial culture had been establish in many country but
popular in Southeast asia country. In Malaysia, K.alvarezii is one of the high
commercial seaweed production and had a big contribution for economy, particularly
in export and import sector. One region that produce high amount of K.alvarezii is
from Sabah. The seaweed production mainly for the industrial purpose but lacking in
exploration for research. With the rapid antibacterial resistance among the
aquaculture industry lead to his study that was conducted to prescreen the potential
of antibacterial from the kappa-carrageenan extraction. The process of prescreening
was according disk-diffusion method by (Kirby-bauer, 1966). There are two type of
bacteria used in this study include E.coli and V.parahaemolyticus. The carrageenan
extract by semi-refine carrageenan method which diluted for three concentration 1, 5
and 20 (mg/ml) for these test where penicillin used as positive control. The high area
zone of inhibition observed was 5mg/ml.
