Abstract

Probiotic is an alternative subtance to prevent fish diseases which is environmentally friendly. The research purpose was to isolate potential probiotic to control bacteria pathogen in barramundi (Lates calcarifer) to control the bacteria pathogen. The probiotic bacteria candidates were isolated from intestine of barramundi by using the spread and streak methods on MRS and TSA media. The antibacterial activity was examinined by using disc diffusion agar method on Zobell 2216E medium. The results showed thirty eight isolates were found which consisted of coccus, white, orange and yellow colonies. Twelve isolates had inhibition against Vibrio alginolyticus,two isolates showed highest inhibition zone and antivibrio activities. The highest inhibition zone (10.04 ± 1,48 mm) and (9,50 ± 2,12 mm) and the antivibrio activities (4.04 mm) and (3.50 mm) were indicated by KPBU2-5 and KPMU2-6 isolates respectively.Keywords: Probiotics, Isolation, Barramundi, Antagonistic.

Abstract

A research on the production, decomposition rate and identification of bacteria on Avicennia alba litter in the coastal zone Kuala Indragiri, Riau Province. This research was aimed to observe the contribution of mangrove forests in the productivity for surrounding environment and conducted from December 2014-March 2015. The litter production was calculated by using litter-trap. Sample was collected once in every 15 days during 45 days of observation. The litterfall was oven-dried and weighed. The result showed that avarage production of litterfall of A. alba in all station was 297.696 g/m2/45days (fresh weight) and 189.763 g/m2/45days (dry weight). The average total shrinking dry weight of litterfall leaf /day was at 0.13225 g/day or 1.3225 %/day. The average reduction dry weight of A. alba litterfall in every station was 7.848 g during 45 days of observation with a percentage value of the decomposed litterfall weight of 78.480% or 0,523 g/day, with final result of litterfall dry weight is 2,152 g. Seven types of bacterial colonies were identified on each station and consisted of Bacillus sp (2), Micrococcus sp, Xanthomonas sp, Pseudomonas sp, Vibrio sp and Escherichia sp.Keywords: Avicennia alba, litter, production, decomposition rate, bacteria, Kuala Indragiri

Abstract

The use of probiotics as an effort to improve the cultivation environment and suppress pathogenic disease proved can help some of the problems in the cultivation of shrimp ponds. This study aimed to determine the effect of the concentration of probiotics effervescent tablets on the growth of Vibrio sp. The method used in the study was an experimental method with 2 treatments, water pond with pond water treatment level is not sterile (non aseptic), pond water that has been sterilized (aseptic) and water pond with bacteria Vibrio sp. and the concentration of probiotics effervescent tablet with a level of treatment 20%, 30% and 40% maltodextrin with 2 repetitions. The ability of probiotics effervescent tablet on the growth of Vibrio sp. it is known to test the TPC (Total Plate Count). Based on the TPC tests have shown that probiotics contained in effervescent tablets with a concentration of 20% maltodextrin has the ability to be most effective in inhibiting or suppressing the growth of Vibrio sp. These indications prove extremely decreasing the amount of bacteria Vibrio sp. on pond water after 48 hours underway. Statistical test result, see from the effect of the concentration of probiotic effervescent tablets on the growth of Vibrio sp. on a shrimp pond water, showed no significant differences (P> 0.05).Keywords: probiotic, effervescent tablets, Vibrio sp., Total Plate Count
