Evaluation of Bacillus albus SMG-1 and B. safensis SMG-2 Isolated from Saemangeum Lake as Probiotics for Aquaculture of White Shrimp (Litopenaeus vannamei): A Recent Study | Chapter 1 | Research Aspects in Agriculture and Veterinary Science Vol. 5

Shrimp farmers are growing increasingly hesitant about which probiotics to trust due to the huge variety of commercially available probiotics for aquaculture and the doubt around the effectiveness of some of the products. The goal of this research was to create microbial strains that could boost white shrimp productivity and increase the quality of probiotic products offered to farmers. Bacillus albus SMG-1 and Bacillus safensis SMG-2 were found to be efficient probiotics for white shrimp (Litopenaeus vannamei) aquaculture. Three experimental groups were grown in water treated with B. subtilis, B. albus SMG-1, or B. safensis SMG-2, while a control group was cultured without probiotics. B. albus SMG-1 and B. safensis SMG-2 were isolated from the water of Saemangeum Lake in Jeollabuk-do, Republic of Korea (35°52’07.3″N, 126°30’29.8″E). 240 white shrimp weighing 0.53 0.01 g (average SD) were randomly distributed in 12 acrylic tanks (50 L) with 20 shrimp each tank for 8-week duplicate trials. Weight gain, feed efficiency, and specific growth rates of the microorganism-inoculated groups were considerably higher than those of the control group after 8 weeks (P 0.05). All groups infected with microorganisms had considerably lower concentrations of total ammonia nitrogen, nitrite, total nitrogen, and total phosphorus than the control group, indicating that B. albus SMG-1 and B. safensis SMG-2 improved water quality. We found the first indication that microorganisms from Saemangeum Lake can be used as probiotics in this investigation. Our findings suggest that B. albus SMG-1 and B.safensis SMG-2 could be employed as new aquaculture probiotics to boost white shrimp productivity. As a result, we feel it is critical in future studies to accurately reveal the microorganism strains that are beneficial for increasing production, to collect reliable information for farmers, and to give effective microorganisms that are tailored for each aquaculture species.
