“…The host organism synthesizes bioactive compounds as primary or secondary metabolites to protect or maintain homeostasis [26]. GBacillus-9, which is isolated from the intestine of the whitespotted bamboo shark, has shown potential in the development of biological additives [12,13]. Thus, investigating the optimal fermentation conditions with high efficiency and low cost is an important strategy to develop biological additives.…”

Bacillus amyloliquefaciens-9 (GBacillus-9), which is isolated from the intestinal tract of the white-spotted bamboo shark (Chiloscyllium plagiosum), can secrete potential antibacterial materials, such as β-1,3-1,4-glucanase and some antimicrobial peptides. However, the low fermentation production has hindered the development of GBacillus-9 as biological additives. In this study, the Plackett-Burman design and response surface methodology were used to optimize the fermentation conditions in a shake flask to obtain a higher yield and antibacterial activity of GBacillus-9. On the basis of the data from medium screening, M9 medium was selected as the basic medium for fermentation. The data from the single-factor experiment showed that sucrose had the highest antibacterial activity among the 10 carbon sources. The Plackett-Burman design identified sucrose, NH 4 Cl, and MgSO 4 as the major variables altering antibacterial activity. The optimal concentrations of these compounds to enhance antibacterial activity were assessed using the central composite design. Data showed that sucrose, NH 4 Cl, and MgSO 4 had the highest antibacterial activities at concentrations of 64.8, 1.84, and 0.08 g L −1 , respectively. The data also showed that the optimal fermentation conditions for the antibacterial material production of GBacillus-9 were as follows: Inoculum volume of 5%, initial pH of 7.0, temperature of 36 • C, rotating speed of 180 rpm, and fermentation time of 10 h. The optimal fermentation medium and conditions achieved to improve the yield of antibacterial materials for GBacillus-9 can enhance the process of developing biological additives derived from GBacillus-9.

Background: The diseases in fish and other economic aquatic species is a great concern, and every year it causes a huge loss in aquaculture sectors. The use of probiotics might be a good option to reduce the disease risk and to enhance the productivity. Methods: We have gathered information from various important research and review articles related to fish diseases, probiotics, and gut microbial community. We have tried our level best to represent the up-to-date information in a concise manner. Results: In this present review, we have demonstrated the various beneficial aspects of probiotics in aquaculture sectors. Probiotics are considered as novel functional agents that have potential implications in influencing the gut microbiota of any aquatic organism. Researchers have already documented that probiotics play a wide spectrum functions (such as decrease diseases and stress, enhance immunity, modulate gut microbiota, helps in nutrition, improve water quality, etc.) in host body. Furthermore, the beneficial effects of probiotics contribute to increase feed value and growth of the animal, and improve spawning and hatching rate in aquaculture system. Here, we have discussed each and every functions of probiotics and tried to correlate with the previous knowledge. Conclusion: The reports regarding the efficacy of probiotics and its detailed mechanism of action are scarce. Till date, several probiotics have been reported; however, their commercial use has not been implicated. Most of the studies are based on laboratory environment and thus the potentiality may vary when these probiotics will be used in natural environments (pond and lakes).

“…in animals from farm 2 is very interesting result, since different Shewanella species have shown good probiotic properties in farmed fish such as Senegalese sole (Jurado et al, 2018), gilthead seabream (Cordero et al, 2016) and abalone (Jiang et al, 2013). Some preliminary studies have shown that the use of some probiotics can enhance the innate immunity and growth performance of sturgeons (Pourgholam et al, 2016;Fei et al, 2018), but the use of Shewanella species in this fish species has not been investigated to date.This study represents the first application of the Illumina next-generation sequencing (NGS) approach to studying the microbiome of the sturgeon's gut and expands previous knowledge acquired through classical cultivation techniques, PCR-DGGE and pyrosequencing (Akrami et al, 2013;Geraylou et al, 2012;Geraylou et al, 2013a;Geraylou et al, 2013b). In this fish species, previous molecular approaches have focused on the effect of prebiotics on bacterial groups such as lactic acid bacteria (Akrami et al, 2013), which are relevant in the microbiome of monogastric mammals (particularly the human gut microbiome) but whose relevance in fish appears much lower or is poorly understood.…”

“…In this context, the development of effective intensive production methods for sturgeon farms requires new strategies, such as the use of target-specific probiotics to prevent infectious diseases. Some preliminary studies have shown that the use of prebiotics and probiotics may be promising for sturgeon farms (Akrami et al, 2013;Pourgholam et al, 2016;Fei et al, 2018). However, the development of pre-and probiotics to improve future sturgeon aquaculture must be guided by an improved understanding of the gut microbiota of healthy sturgeons in the specific conditions where the fish live and grow (temperature, water, diet and other factors).…”

Abundant bacteria in the proximal and distal intestine of healthy Siberian sturgeons (Acipenser baerii)

The gut microbiota plays a key role in animal health, including immune and metabolic homeostasis. Despite the economic relevance of the sturgeon, studies addressing the gut microbiome of this species are scarce and have focused only on the hindgut. The objective of this work was to use Illumina metabarcoding technology to compare the bacterial microbiomes of two different intestinal locations, the proximal intestine (small intestine) and the distal intestine (hindgut containing the spiral valve), of healthy Siberian sturgeons (Acipenser baerii) reared on two different farms in Spain. Although a high degree of interindividual variability was observed, certain differences between the anatomical parts and between the geographical locations were clear. The results show that the sequences corresponding to the most abundant taxa were the basis for clustering according to anatomical region (proximal and distal intestine), whereas the less abundant taxa were the basis for clustering according to the geographical location of the fish farms. Finally, the results also indicate the existence of certain bacteria that are present in the intestinal tracts of all the fish analyzed in this study; this information may be useful in future studies aiming to establish differences based upon fish health or disease.
