Circadian cycle of digestive enzyme production at fasting and feeding conditions in Nile tilapia, Oreochromis niloticus (Actinopterygii: Perciformes: Cichlidae) [PDF]

Acta Ichthyologica et Piscatoria, 2016
Background. Fish have photoperiod-dependent rhythms (circadian cycle of about 24 h), including the enzymatic secretion cycles, and this information has not been available for Nile tilapia, Oreochromis niloticus (Linnaeus, 1758).

Fish muscle hydrolysate obtained using largemouth bass Micropterus salmoides digestive enzymes improves largemouth bass performance in its larval stages.

PLoS ONE, 2021
The present study utilized digestives tracts from adult largemouth bass (LMB) to hydrolyze Bighead carp muscle and obtain an optimal profile of muscle protein hydrolysates that would be easily assimilated within the primitive digestive tract of larval ...

DIGESTIVE ENZYMES, IMMUNITY AND OXIDATIVE STATUS OF NILE TILAPIA (Oreochromis niloticus) REARED IN INTENSIVE CONDITIONS

Slovenian Veterinary Research, 2019
High stocking density is significantly disturbing the growth and productivity of aquatic animals. Digestive enzymes, immunity and oxidative status of Nile tilapia were investigated in case of culturing in several densities.

Application of enzymes in anaerobic digestion

Water Science and Technology, 2007
Owing to the very low economic value of brewer's spent grains, its utilisation for biogas production is very promising. The hydrolysis of ligno-cellulose is the rate limiting step in anaerobic digestion. Enzymatic pre-treatment promotes the hydrolysis of ligno-cellulose, breaking it down to lower molecular weight substances which are ready to be ...

Sanguinarine in Chelidonium majus induced antifeeding and larval lethality by suppressing food intake and digestive enzymes in Lymantria dispar.

Pesticide Biochemistry and Physiology, 2019
Our previous studies had identified that both crude extracts and total alkaloid from Chelidonium majus exerted a significant antifeeding and larval lethality on Lymantria dispar.

State of knowledge about biotechnological uses of digestive enzymes of marine fishery resources: A worldwide systematic review

Aquaculture and Fisheries
The characterization of digestive enzymes presents in fish and their potential biotechnological uses is a well-developed and studied field. However, there has not been a systematic review that analyzes the state of knowledge of these enzymes at a global ...

Gut Digestive Function and Microbiome after Correction of Experimental Dysbiosis in Rats by Indigenous Bifidobacteria

Microorganisms, 2021
In recent years, great interest has arisen in the use of autoprobiotics (indigenous bacteria isolated from the organism and introduced into the same organism after growing).

Digestive proteinases from marine organisms and their applications [PDF]

Songklanakarin Journal of Science and Technology (SJST), 2008
Fish viscera have wide biotechnological potential as a source of digestive enzymes, especially proteinases. The biological diversity of fish species provides a wide array of enzymes with unique properties. Fish digestive proteolytic enzymes most commonly

Activity and post-prandial regulation of digestive enzyme activity along the Pacific hagfish (Eptatretus stoutii) alimentary canal.

PLoS ONE, 2019
Hagfishes are living representatives of the earliest-diverging vertebrates and are thus useful for the study of early vertebrate physiology. It has been previously postulated that digestive enzymes account for the majority of digestion because hagfish ...
