“…Biswas et al. () reported that lzm transcript levels were increased after feeding of a NT‐rich baker's yeast extract for kuruma shrimp ( Marsupenaeus japonicus ). Acid phosphatase (ACP) and alkaline phosphatase (ALP) act as immune parameters which catalyse the hydrolysis of various phosphate‐containing compounds, and they act as trans‐phosphorylases at acidic and alkaline pH, respectively.…”

“…The Pacific white shrimp ( Litopenaeus vannamei ) is a commercially important shrimp species that is widely cultured in China because of its rapid growth, tender flesh, high nutritional value and ability to perform well in high‐density culture (Amaya, Davis, & Rouse, ). As previous studies reported, shrimps, like other invertebrates, depend on innate immune system rather than on non‐existent acquired immunity for protection against invading pathogens (Biswas et al., ). Besides, NT supplementation may meet the requirements of rapidly dividing and differentiating cells, and intestinal amelioration and repair and then improve gastrointestinal physiology and morphology (Burrells, Williams, & Forno, ; Cheng, Buentello, & Gatlin, ; Li & Gatlin, ).…”

An 8‐week feeding trial was conducted to evaluate the effects of dietary nucleotide (NT)‐rich yeast supplementation on growth, innate immunity and intestinal morphology in Pacific white shrimp (Litopenaeus vannamei). Four isonitrogenous and isolipidic practical diets were formulated to contain 0 (control), 10, 30 and 50 g/kg of NT‐rich yeast, respectively. A total of 480 shrimp with an average initial body weight of 1.86 ± 0.02 g were randomly allocated into four groups, with four replicates per group and 30 shrimp each replicate. The results indicated that shrimp fed the diet containing 50 g/kg NT‐rich yeast had significantly higher weight gain (WG), specific growth rate (SGR) and protein efficiency ratio (PER) than those fed the control diet, and the lowest feed conversion ratio (FCR) was observed in the shrimp fed the 50 g/kg NT‐rich yeast supplemental diet. However, there was no significant difference in survival among all treatments. The crude protein of whole shrimp in the 50 g/kg NT‐rich yeast group was higher than that in the control group. Total protein, triglyceride concentrations, the activities of aspartate aminotransferase and alanine aminotransferase in serum were significantly influenced by the dietary NT‐rich yeast supplementation. The activities of serum phenoloxidase (PO) and lysozyme (LZM) of shrimp fed the diet containing 50 g/kg NT‐rich yeast were higher than those in shrimp fed the other diets. Relative expressions of alp and lzm significantly upregulated in the 30 g/kg NT‐rich yeast group compared to the control group. The intestinal fold height and fold width in the 30 g/kg NT‐rich yeast group were significantly higher than those fed the control diet; and the highest microvillus height occurred in the shrimp fed the 50 g/kg NT‐rich yeast diet. In summary, dietary 30–50 g/kg NT‐rich yeast supplementation promotes growth performance, enhances innate immunity and improves intestinal morphology of Litopenaeus vannamei.

“…The microbial biomass from different sources may be used as additive or as an ingredient to partially substitute other sources of protein in animal feeds; in the case of aquaculture, fish meal and soybean meal. Relatively recent studies have demonstrated that the whole, untreated biomass or the extracted products from yeast, bacteria and microalgae elicit important growth and immunostimulatory effects in larvae and juveniles of aquatic organisms (Daniels et al 2010;Biswas et al 2012;Macias-Sancho et al 2014;Vidakovic et al 2015). It has been also demonstrated that yeast and photosynthetic bacteria can be successfully produced and used for zooplankton culture and as fish meal replacement ingredients (Kim & Lee 2000;Olvera-Novoa et al 2002;Loo et al 2013;Gamboa-Delgado et al 2016a).…”

Fisheries and aquaculture products will have a lead role in satisfying the food requirements of the growing human population. The fish meal required for the manufacture of aquaculture feeds represents a limited resource having high demand. Unconventional sources of nutrients have been intensely researched and among these, the microbial biomass produced from heterotrophic and autotrophic microorganisms has been considered as a promising substitute for animal‐ and plant‐derived ingredients. Several studies have shown that different species of yeast, bacteria and microalgae are viable for high density culture and show excellent nutritional characteristics for terrestrial and aquatic animals. Such features have lead to additional research to upscale production and although production costs are still high; novel, sophisticated methods have focused on utilizing alternative substrates for producing microbial biomass. The aquaculture industry requires renewable nutrient sources that can yield high quality protein and other essential nutrients. In this context, the nutritional characteristics of microorganisms and the emerging technologies aimed to produce microbial biomass allow forecasting increased applications. The present manuscript reviews the current state of the production and use of microorganisms as dietary ingredients in aquaculture nutrition, with emphasis on those showing solid potential as functional additives and fish meal replacement ingredients. A synthesis of recent results on the effects promoted by the dietary inclusion of microbial biomass is presented, underlining the employment of different sources of yeast, bacteria and microalgae and the physiological ability of aquatic animals to utilize these alternative nutrient sources.

“…Some of the yeast species can make partial replacement of fishmeal or soybean protein [10]. The efficacy of live yeasts as diet compliments in aquaculture diets have been tested by many workers and reported the ability to enhance growth, achieve better FCR (Feed Conversion Ratio) and immune enhancing properties in aquaculture animals, such as shrimps [11], [12]. In the present study, Debaryomyces hansenii a marine yeast was incorporated in the diets of shrimp L.vannamei and various growth parameters were estimated during the culture period.…”
