Abstract
    This study evaluated the effects of four microbes, Candida parapsilosis, Pseudoalteromonas flavipulchra, Lactobacillus sakei, and Bacillus natto on suppression of Vibrio, survival rate, enzyme activity, chemical composition, and microbial longevity in the brine shrimp, Artemia franciscana. Five treatments, including four experimental groups and a control group, each with four replicates, were studied. The concentration of 108 CFU mL−1 of each mentioned strain was used to feed the nauplii for 2 weeks. The results demonstrated that the use of L. sakei, P. flavipulchra, and B. natto significantly suppressed the concentration of Vibrio over 5, 10, 15, and 20 h of enrichment respectively. From the selected microbes, B. natto and L. sakei were significantly colonized in the population and increased the enzyme activity. The longevity of B. natto in the Artemia was recorded as the best bacteria for long-term inoculation as after 8 days of starvation of Artemia, the count of B. natto was increased. The findings showed that B. natto appears to be a promising probiotic for Artemia in the suppression of Vibrio and also in increasing population growth, enzyme activity, and long-term colonization potential.
