“…Nowadays, the 16S rRNA gene sequencing has been widely used for the bacterial identification (Woese et al, 1990). Several strains from Bacillus genus have been previously reported to effectively protect cultured aquaculture species from pathogens (Mishra, 2011;Silva et al, 2012;Laranja et al, 2017;Mukherjee et al, 2019;Hu et al, 2021). Besides, other studies have demonstrated that the dietary species of Bacillus species, including B. cereus, B. subtilis, and B. subtilis T13 (Wu et al, 2014), have improved the sea cucumber's growth and quality of water against pathogens (Galagarza et al, 2018).…”

Probiotic Potential of Indigenous (Bacillus sp. RCS1, Pantoea agglomerans RCS2, and Bacillus cereus strain RCS3) Isolated From Cobia Fish (Rachycentron canadum) and Their Antagonistic Effects on the Growth of Pathogenic Vibrio alginolyticus, Vibrio harveyi, Streptococcus iniae, and Streptococcus agalactiae

Large-scale fish farming faces many environmental stresses, which affect their immune systems, growth performance, and physiological homeostasis, resulting in increase in their susceptibility to infections. Some of the most common bacterial infections of cobia fish (Rachycentron canadum) include streptococcosis, vibriosis, furunculosis and mycobacteriosis, and pastelleurosis. Probiotics could be helpful in reducing or limiting the incidence of severe disease infections or outbreaks. Therefore, the present study aimed to isolate the indigenous bacterial species from healthy cobia fish and then selected 3 strains, including Bacillus sp. RCS1 (MW560712), Pantoea agglomerans RCS2 (MW560713), and Bacillus cereus RCS3 (MW560714) from the gut of juvenile’s cobia having advantageous assets or positive characteristics. Their analysis indicated the presence of similar biochemical profiles and all could effectively utilize carbon sources. The biosafety assessment did not show any pathological symptoms after 10 days of injecting the fish with isolated bacteria. The results showed that all the isolated bacteria in the present study had low auto-aggregation capacity within the first 3 h of incubation. The isolated bacteria showed strong tolerance when exposed to a range of pH. Although asymmetrically, a slow rise in the growth of isolated bacteria was observed within the pH range of 1–8 for RC1, 1–7 for RC2, and 1–6 for RC3. The antagonistic effects of isolated bacterial strains on the development of pathogens, including Vibrio alginolyticus, Vibrio harveyi, Streptococcus iniae, and Streptococcus agalactiae, were investigated using Luria-Bertani (LB) agar plates. All the isolated bacteria exhibited inhibitory effects against the pathogens, including V. alginolyticus, V. harveyi, S. iniae, and S. agalactiae. These isolated bacteria were characterized with a wide range of antagonistic activities, non-hemolytic activities, high survivability after heat-treatments and safety confidence, and antibiotic susceptibility. Generally, the characteristics displayed by these strains indicated that they could be used as potential probiotics in the aquaculture industry.

“…Lysozyme is the cationic and crucial antibiotic enzyme that can demolish β‐glycosidic bonds of bacterial cell walls, particularly in Gram‐positive bacteria (Banavreh et al, 2019b; Di et al, 2019). A plethora of data revealed that the dietary probiotic supplementation increments the lysozyme activity (Mukherjee et al, 2019; Sadat Hoseini Madani et al, 2018). However, some researchers have claimed that supplemental dietary probiotics did not affect serum lysozyme.…”

“…IgM is the main antibody in fish and major parts of the humoral immune system that cooperates with the opsonization of pathogens, promoting their phagocytosis (Mukherjee et al, 2019; Vallejos‐Vidal et al, 2016). Indeed, numerous studies showed that probiotic bacteria could incite immunoglobulins in fish.…”

Sturgeons are one of the most popular and valuable marketable fish species in the world in terms of their caviar and meat. The sturgeon species owing to indiscriminate fishing, water pollution, destroy of spawning places, and construction of dams, are listed as endangered fish by International Union for Conservation of Nature (IUCN, 2018). Today, sturgeon farming has been expanded rapidly in the world. Among the aquaculture of sturgeons, great sturgeon, Huso huso, has made a promising candidate because of high growth, resistance to stress factors and reception of formulated diets (Matani Bour et al.,

“…Some researchers have achieved good results in enhancing the growth and improving the immune function of tilapia using probiotics (Xia et al, 2019; Yih et al, 2019), and additionally, research indicates that the effects of mixed use of multiple probiotics is better than single probiotics (Mukherjee et al, 2019; Vazirzadeh et al, 2020). Meanwhile, studies on tilapia have also confirmed that probiotics can inhibit the growth and reproduction of intestinal pathogenic microorganisms by secreting bacteriostatic substances, thereby improving the body's immune characteristics (Del'Duca et al, 2013; Yih et al, 2019).…”

Dietary supplementation of Bacillus subtilis and Enterococcus faecalis can effectively improve the growth performance, immunity, and resistance of tilapia against Streptococcus agalactiae

The combined probiotics (four different combination of Bacillus subtilis, Bacillus licheniformis and Enterococcus faecalis) were used and the growth performance, immunity, gut morphology and resistance to Streptococcus agalactiae of tilapia (Oreochromis mossambicus) were comprehensively evaluated after 42 days feeding on supplemented diets. Results showed that the growth performance of tilapia in PG2 (with B. subtilis and E. faecalis) was the best. Moreover, the strong positive association of some indices with specific probiotics was demonstrated for lipase activity, SI, LYZ, C3, T‐AOC and CAT were higher in PG2, indicating that the specific probiotics, and not diversiform probiotics, were the key determinants of the results for tilapia. The better gut villi length, villi width and muscular thickness in fishes under PG2, which shows that specific probiotics can promote the good development of gut mucosal structure of tilapia. Over 76% survival rate for tilapias against S. agalactiae in the PG2 may be because the B. subtilis and E. faecalis provided a better gut micro‐ecological environment. Totally, B. subtilis and E. faecalis may be specific to tilapia gut microbes.
