Gut Microbiota and Energy Homeostasis in Fish

Frontiers in Endocrinology, Journal Year: 2019, Volume and Issue: 10

Published: Jan. 23, 2019

The microorganisms within the intestinal tract (termed microbiota) have been shown to interact with gut-brain axis, a bidirectional communication system between gut and brain mediated by hormonal, immune neural signals. Through these interactions, microbiota might affect behaviors, including feeding behavior, digestive/absorptive processes (e.g. modulating motility barrier), metabolism, as well response, repercussions on energy homeostasis health of host. To date, research in this field has mostly focused mammals. Studies non-mammalian models such fish may provide novel insights into specific mechanisms involved microbiota-brain-gut axis. This review describes our current knowledge possible effects feeding, digestive processes, growth fish, emphasis influence hormones, environmental factors inter-specific differences.

Fish intestinal mucosal surfaces comprise of a complex and dynamic community microorganisms, which play important roles within the gastrointestinal (GI) tract. Of bacteria colonising GI tract, lactic acid (LAB), are generally considered as favourable due to their abilities stimulating host development, digestive function, maintaining tolerance, immune response provide protection towards bacterial pathogens. In early finfish studies culture-dependent methods were used enumerate population levels tract; members Lactobacillus, Lactococcus, Leuconostoc, Enterococcus, Streptococcus Carnobacterium genera isolated. However, limitations by using culture media, techniques such denaturing gradient gel electrophoresis (DGGE), temporal temperature (TTGE), 16S rRNA clone libraries, MiSeq sequencing genes have been during last decade. These investigations revealed presence Streptococcus, Carnobacterium, Weissella Pediococcus indigenous species. tract warm water fish species, commonly identified, however, rarely identified.

Probiotic application for sustainable aquaculture

Reviews in Aquaculture, Journal Year: 2018, Volume and Issue: 11(3), P. 907 - 924

Published: July 9, 2018

Abstract Aquaculture, which constitutes one of the largest food production sectors in world, is preferably practiced with natural organic products rather than synthetic chemicals or antibiotics. In addition to daunting challenge providing and livelihood exponentially increasing world population, aquaculture industry key ensuring that development based on environmentally sustainable practices, specifically aquafeeds. Terrestrial microorganisms act as defence systems cultured species have been identified main producer for beneficial bacterial candidates. Probiotics recently gained popularity microbes candidates organisms maintain health condition well‐being different aquatic animals. This review aimed understand necessity using probiotics a alternative regulate growth performance, feed utilisation general aquaculture. Also, explanatory discussion about host microbiota its ability produce probiotic strains functionality ameliorate immunity provide interactive effects host‐derived probiotics.

Role of lactic acid bacteria in flavor development in traditional Chinese fermented foods: A review

Critical Reviews in Food Science and Nutrition, Journal Year: 2020, Volume and Issue: 62(10), P. 2741 - 2755

Published: Dec. 30, 2020

Traditional Chinese fermented foods are favored by consumers due to their unique flavor, texture and nutritional values. A large number of microorganisms participate in the process fermentation, especially lactic acid bacteria (LAB), which present almost all contribute flavor development. The formation is complex involves biochemical conversion various food components. It very important fully understand direct foods. comprehensive link between LAB community traditional reviewed. main mechanisms involved dominated carbohydrate metabolism, proteolysis amino catabolism, lipolysis fatty metabolism. This review highlights some useful novel approaches for enhancement, including application functional starter cultures metabolic engineering, may provide significant advances toward improving a promising market.

Aquaculture is the fastest growing animal food sector worldwide and expected to further increase feed human population. However, existing (re-)emerging diseases are hampering fish shellfish cultivation yield. For many diseases, vaccination protocols not in place excessive use of antibiotics other chemicals substantial concern. A more sustainable disease control strategy protect from could be achieved by introduction or augmentation beneficial microbes. To establish maintain a 'healthy' microbiome, fundamental understanding diversity temporal-spatial dynamics fish-associated microbial communities their impact on growth health aquatic hosts required.

The constant increase of aquaculture production and wealthy seafood consumption has forced the industry to explore alternative more sustainable raw aquafeed materials, plant ingredients have been used replace marine feedstuffs in many farmed fish. objective present study was assess whether plant-based diets can induce changes intestinal mucus proteome, gut autochthonous microbiota disease susceptibility fish, these could be reversed by addition sodium butyrate diets. Three different trials were performed using teleostean gilthead sea bream (Sparus aurata) as model. In a first preliminary short-term trial, fish fed with additive (0.8%) supplementing basal diet low vegetable inclusion (D1) then challenged bacteria detect possible effects on survival. second greater levels (D2, D3) long-term effect at lower dose (0.4%) added D3 (D4 diet) tested proteome microbiome. third effectiveness (D4) prevent outcome after an parasite (Enteromyxum leei) challenge tested. results showed that opposed forces driven dietary supplementation diet.
