Effects of dietary melanoidins on digestive physiology, nutrient digestibility and plasmatic antioxidant capacity of the rainbow trout Oncorhynchus mykiss
(2018)
Melanoidins are complex molecules usually found within dietary matrixes suffering heating steps during the production process. These compounds are known to exert a number of negative effects on the digestibility of nutrients ...
Duplications and functional convergence of intestinal carbohydrate-digesting enzymes
(Oxford University Press, 2020-02)
Vertebrate diets and digestive physiologies vary tremendously. Although the contribution of ecological and behavioral features to such diversity is well documented, the roles and identities of individual intestinal enzymes ...
Microbial diversity and digestive enzyme activities in the gut of earthworms found in sawmill industries in Abeokuta, Nigeria
(Universidad de Costa Rica, 2014)
Fully reversible phenotypic plasticity of digestive physiology in young house sparrows: lack of long-term effect of early diet composition
(Company of Biologists, 2011-08)
Feeding conditions during the nestling period may significantly affect whole-life fitness in altricial birds but little is known about the physiological mechanisms responsible for these effects. Permanent changes (irreversible ...
Feeding and osmoregulation in the euryhaline crab Neohelice granulata: Digestive parameter responses
(Brill Academic Publishers, 2019-09)
When a species often experiences variation in its environmental conditions, metabolic flexibility is required. We studied the duration of the digestive cycle and the activity of key digestive enzymes (proteolytic, amylase, ...
Growth performance and metabolic responses of Nile tilapia fed diets with different protein to energy ratios
(2022-01-30)
The effect of dietary digestible protein to digestible energy (DP/DE) ratio on the growth performance and metabolic responses of Nile tilapia juveniles was evaluated. Five experimental diets were formulated with increasing ...
Effects of Aspergillus spp. exogenous fibrolytic enzymes on in vitro fermentation of tropical forages
(WILEY-BLACKWELLHOBOKEN, 2012)
BACKGROUND: Cellulose and hemicellulose are quantitatively the most important structural carbohydrates present in ruminant diets. Rumen micro-organisms produce enzymes that catalyse their hydrolysis, but the complex network ...
Structure and function of the foregut and salivary glands of the synanthropic diplopod Urostreptus atrobrunneus (Spirostreptidae)
(Brill Academic Publishers, 2014)
Teaching nutritional biochemistry: An experimental approach using yeast
(American Physiological Society, 2012-12)
In this report, we present a practical approach to teaching several topics in nutrition to science students at the high school and college freshmen levels. This approach uses baker's yeast (Saccharomyces cerevisiae) as a ...
Endoglucanase activity in Neoteredo reynei (Bivalvia, Teredinidae) digestive organs and its content
(2018-06-01)
Cellulolytic enzymes have been studied in several organisms, such as insects, molluscs and other organisms, which can have enzymes endogenously produced or by symbiotic microorganisms. These enzymes are responsible for ...
