The most frequent disease on vannamei shrimp is caused by Vibrio sp. bacterial infection. Vibrio sp. might cause a serious production loss in the shrimp culture, leading to larvae and mature stadium mortality at 50%. To date, vibriosis disease has yet to be controlled properly. Therefore, sponge-associated bacteria are used as an alternative to control vibriosis disease in shrimp. To maintain and protect the potential bacteria from unfavorable environmental influence, combining the ability of sponge-associated bacteria and encapsulation technology is necessary. This research aimed to evaluate the viability, shelf life, anti-vibrio activity, and structure characteristics under Scanning Electron Microscope (SEM) of Bacillus spp. microencapsulation using alginate, chitosan, as well as Arabic gum. The method of viability test used Total Plate Count (TPC) and to reconfirm the antibacterial test was conducted using plug agar method. The result indicates that the B. altitudinis PH.1 coated with chitosan show the highest viability at 1.8x108 CFU/ml after 14 days preserved in -20C. The moisture content of this treatment revealed 17% as the highest than the other treatment, therefore the predicted shelf life for chitosan coated reach 9.1 years. Furthermore, the antivibrio of B. altitudinis PH.1 show the strong activity with clear zone inhibition at 16.07 mm against Vibrio alginolyticus. The structure of B. altitudinis PH.1 under SEM observation was irregular shape and size. Therefore, this study found that chitosan could be an alternative source to preserve a potential bacterium using microencapsulation technology.

“…Besides seaweed (Sugumaran et al 2022), Vibrio sp. causes ice-ice disease in fish and shrimp (Sarjito et al 2022). Contamination of the bacteria in seafood leads to extra-intestinal infections in humans due to the consumption of raw or undercooked seafood products (Cao et al 2018).…”

Abstract. Tuhumury NC, Sahetapy JMF, Matakupan J. 2024. Isolation and identification of bacterial pathogens causing ice-ice disease in Eucheuma cottonii seaweed at Seira Island Waters, Tanimbar Islands District, Maluku, Indonesia. Biodiversitas 25: 964-970. Seaweed cultivation has proven to be beneficial and enhances the well-being of communities. Production of seaweed in the waters of Maluku has increased despite facing the problem of ice-ice disease. Therefore, this research aimed to isolate and identify bacteria on the Eucheuma cottonii seaweed species affected by ice-ice disease in the waters of Seira Island, Tanimbar Islands District, Maluku. It was conducted in August 2023 at three observation stations, and water quality samples were collected in situ at all three stations, including temperature, salinity, pH, dissolved oxygen (DO), and turbidity. Furthermore, bacterial isolation and identification were carried out at the Laboratory of Marine Aquaculture, Ambon. Bacteria isolation and purification were performed on TCBS media using the streak plate technique, while identification used the API 20E test. The results showed that water quality parameters supported seaweed growth. Four bacteria that caused ice-ice disease in the waters of Seira were identified as Vibrio alginolyticus, Vibrio fluvalis, Vibrio cholerae, and Aeromonas caviae. Moreover, all four bacteria found were gram-negative and pathogenic. Bacteria belonging to the genera Vibrio and Aeromonas have been proven to cause infections in marine organisms, including seaweed. In conclusion, four types of bacteria were identified in seaweed affected by ice-ice disease.
