The Amazonian catfish, Panaque nigrolineatus have several physiological adaptions enabling the scraping and consumption of wood (xylivory), facilitating a detritivorous dietary strategy. Composed of lignocellulose, wood is a difficult substrate to degrade and as yet, it is unclear whether the fish obtains any direct nutritional benefits from wood ingestion and degradation. However, there are numerous systems that rely on microbial symbioses to provide energy and other nutritional benefits for… Expand
Effect of Diet on the Enteric Microbiome of the Wood-Eating Catfish Panaque nigrolineatus
TLDR
These findings suggest that the P. nigrolineatus gut environment selects for an enteric community based on function, rather than a vertically transferred symbiotic relationship, which may provide an advantage to an organism that switches between dietary strategies to survive a highly variable environment.

Wood degradation by Panaque nigrolineatus, a neotropical catfish: diversity and activity of gastrointestinal tract lignocellulolytic and nitrogen fixing communities
TLDR
This chapter focuses on the Neotropical catfish, Panaque nigrolineatus, which ingests large quantities of wood as part of its diet and has been shown to include bacterial and fungal communities participating in both lignocellulose degradation and nitrogen fixation that are taxonomically distinct from all other wood-feeding organisms.

The Intestinal Mycobiota in Wild Zebrafish Comprises Mainly Dothideomycetes While Saccharomycetes Predominate in Their Laboratory-Reared Counterparts
TLDR
This pioneer study has shed light into the differences in the intestinal fungal communities of wild-caught and laboratory-reared zebrafish and the baseline data generated will enrich knowledge on fish mycobiota. Expand
Gut microbiomes of sympatric Amazonian wood‐eating catfishes (Loricariidae) reflect host identity and little role in wood digestion
TLDR
Describing the gut microbiome of two co‐occurring catfish genera and four species revealed that the majority of wood digesting pathways were at best equivalent to and more often depleted or nonexistent within the catfish gut compared to the submerged wood, suggesting a minimal role for the Gut microbiome in wood digestion. Expand
Comparison of fungal community composition within different intestinal segments of tilapia and bighead carp
Although intestinal fungi play important roles in host health and disease, the composition and diversity of fungal communities remain poorly reported in fish. In this study, fungi in the fore-, mid-,Expand
Physiology and enzymology of lignocellulose digestion in the shipworm Lyrodus pedicellatus
TLDR
Results indicate that bacterial lignocellulolytic enzymes are expressed in the gills, while the endogenous enzymes are mainly produced by the digestive glands, with complementary CAZy classes being expressed by the bacteria and the shipworms, indicating a subdivision of roles. Expand

Phylogenetic Analysis of Microbial Communities in Different Regions of the Gastrointestinal Tract in Panaque nigrolineatus, a Wood-Eating Fish
TLDR
Using 16S rRNA gene phylogeny, it is reported that the P. nigrolineatus gastrointestinal tract possesses a microbial community closely related to microorganisms capable of cellulose degradation and nitrogen fixation. Expand
Examination of a Culturable Microbial Population from the Gastrointestinal Tract of the Wood-Eating Loricariid Catfish Panaque nigrolineatus
TLDR
This study verifies the presence of a resident microbial community in the gastrointestinal tract of P. nigrolineatus by fluorescence microscopy and focuses on the cellulose-degrading members by culture-based and 13 C-labeled cellulose DNA stable-isotope probing (SIP) approaches. Expand
Nitrogenase diversity and activity in the gastrointestinal tract of the wood-eating catfish Panaque nigrolineatus
TLDR
The intake of a cellulose rich diet and the presence of a suitable environment for nitrogen fixation suggest that the GI tract microbial community may allow a unique trophic niche for P. nigrolineatus among fish. Expand
Digestive enzyme activities and gastrointestinal fermentation in wood-eating catfishes
TLDR
Wood-eating catfishes appear to be detritivores reliant on endogenous digestive mechanisms, as are other loricariid catfishing, which stands in contrast to truly “xylivorous” taxa which are reliant on an endosymbiotic community of microorganisms to digest refractory polysaccharides. Expand
Microbial diversity of intestinal contents and mucus in yellow catfish (Pelteobagrus fulvidraco)
TLDR
The traditional culture-based techniques and the 16S rDNA sequencing method were used to investigate the microbial community of the intestinal contents and mucosal layer in the intestine of yellow catfish, and the abundance and diversity of bacterial populations in mucus might be different from the microbiota in gut contents. Expand
Microbial population dynamics in the faeces of wood‐eating loricariid catfishes
TLDR
The diet‐associated in situ microbial diversity and population dynamic in the faeces of catfish exposed to consecutive diets of pellet food and then wood are characterized and extensive microbial diversity was found in catfish faece, evidenced using culture‐independent molecular techniques. Expand
Inside the guts of wood-eating catfishes: can they digest wood?

TLDR
Results corroborate digestive enzyme activity profiles and gastrointestinal fermentation levels in the fishes’ GI tracts, suggesting that the wood-eating catfishes are not true xylivores such as beavers and termites, but rather, are detritivores like so many other fishes from the family Loricariidae.

Phylogenetic Analysis of Intestinal Microflora Indicates a Novel Mycoplasma Phylotype in Farmed and Wild Salmon
TLDR
Analysis of short-chain fatty acids in the digestive tract indicated that the decreasing redox gradient from proximal to distal reaches common to homeothermic animals was absent in salmon, and that the bacterial fermentation levels were much lower than are reported in homeothermac animals. Expand
Live yeasts in the gut: Natural occurrence, dietary introduction, and their effects on fish health and development
TLDR
The present state of knowledge concerning the importance of yeasts in fish gut is summarized, while trying to elucidate the mode of action, and determine whether cellular viability is a prerequisite for efficacy. Expand
Quantitative and Qualitative Changes of the Gastrointestinal Microflora of Pike-Perch ( Stizostedion LuciopercaL. 1758) in Egirdir Lake
TLDR
In pike perch, Staphylococcus and Moraxella were determined as a dominant group that were differed from microflora of digestive system of the other freshwater fish. Expand
