Abstract :

Seaweed can not be differentiated between root, leaves and trunk. Fluktuate and extreame of sea water condition cause Kappaphycus alvarezii seaweed susceptible to get ice-ice disease. Appearing of white patches at thallus of infected seaweed. Suspected ice-ice disease is caused by pattogen bacteria namely Vibrio fluvialis. Vibrio fluvialis is patogen bacteria that cause ice-ice disease seaweed, gram negative bacteria that has body shape like steam and bend. This bacteria can grow in the aquatic ecosystem that is influenced by abudance of nutrient availability, pH, temperature, hardness and salinity. The purpose of this research is to know the viability of Vibrio bacteria at difference salinity. This research is started by identify bacteria until spesies level through biochemical test whit reference SNI 01-2332-4-2006 and identification book (Cowan 2003). Viability is observed three time repetition at TCBS palte media with salinity 30, 32, and 34 ppt, and confirmation test. Bacteria is planted at oblique TSA media with salinity levels 0 ppt, 20 ppt, 40 ppt, 60 ppt, 80 ppt and 100 ppt . the results obtained shows the bacteria grow normally at all test medias except at 100 ppt media. This shows that Vibrio fluvialis bacteria is a bacteria that can grow well at high salinity levels (halofilik).
