Random amplification of polymorphic DNA (RAPD) typing of carnobacteria isolated from hindgut chamber and large intestine of Atlantic cod (Gadus morhua l.)

Energy dilution with α-cellulose in diets for Atlantic cod (Gadus morhua L.) juveniles — Effects on growth, feed intake, liver size and digestibility of nutrients

“…Herbivore fish have caecal pouches for microbial digestion, and Seppola et al (2006) found similar distal fermentation chambers in cod. Atlantic cod were found to compensate the high anti nutrient and fibre contents in diets by increasing feed intake and growth of the intestines to keep good somatic growth (Refstie et al, 2006a;Hansen et al, 2007a).…”

“…If we speculate, the reason might be that the bacterial load in the distal intestine increased due to increased levels of α-cellulose (bacterial load was not measured). Significant numbers of bacteria are previously observed in the lower intestinal tract of cod (Hansen et al, 2006;Seppola et al, 2006). The increased α-cellulose could have resulted in α-cellulose being an available energy source for the bacteria, which again may have increased bacteria production of short chain fatty acids.…”

Analysis of Enzyme Activities of the Gut Bacterial Communities in Labeo rohita fed Differentially Treated Animal Fleshing Diets

“…The gastrointestinal (GI) tract of fish is a complex ecosystem possessing a dense bacterial population levels consisting of aerobic, facultative anaerobic and obligate anaerobic bacteria [64][65][66][67][68][69].that can be defined as either autochthonous (indigenous) or allochtonous (transient) depending upon its ability to adhere and colonize the mucus layer in the digestive tract [36,37,70].…”

Characterization of Leuconostoc strains isolated from fresh anchovy (Engraulis anchoita)

“…Several studies have demonstrated that LAB have been found in marine and freshwater fi sh (mainly from the gastrointestinal tract and gills) and their surrounding environment (Bucio et al, 2006;González et al, 2000;Ringø et al, 2000Ringø et al, , 2002Seppola et al, 2006). Moreover, LAB have recently become a major source of concern in aquaculture due to their pathological signifi cance (Michel et al, 1997).…”
