Digestive enzymes in the germ-free animal.
The digestive physiology of the germ-free animal has a number of characteristics (cecal hypertrophy, slower small intestine cell renewal, slower gastric emptying and intestinal transit) which distinguish it from that of the conventional animal. If the germ-free model is to be used to determine the role of gastrointestinal microflora in the nutrition of the conventional animal, it is essential t...
متن کاملUse of Germ-Free Animal Models in Microbiota-Related Research.
The large intestine is a home for trillions of microbiota, which confer many benefits on the host, including production of vitamins, absorption of nutrients, pathogen displacement, and development of the immune system. For several decades, germ-free animals have been used to study the interaction between the host and its microbiota. This minireview describes the technical aspects for establishi...
متن کاملDigestive Enzymes in Marine Species
The proteolytic activities of the digestive tract of three carnivorous fish species (Sebastes mentella, Scophthalmus maximus, Sparus aurata) have been studied. The activity found in the stomach showed a pH optimum of 2.0 for all species, whereas this was in the alkaline range (9.5-10.0) in the intestinal extracts. Similar optimal temperature was measured for all species, although higher residua...
متن کاملConservation of digestive enzymes.
The traditional understanding is that an entirely new complement of digestive enzymes is secreted by the pancreas into the small intestines with each meal. This is thought to be necessary because, like food itself, these enzymes are degraded during digestion. In this review we discuss experiments that bring this point of view into question. They suggest that digestive enzymes can be absorbed in...
متن کاملCharacteristics of some digestive enzymes in sobaity, Sparidentex hasta
Background: Determination of digestive enzymes activity would provide critical information in the design of appropriate diet. Sobaity, Sparidentex hasta is found in the Persian Gulf and cultured in countries adjacent to it. OBJECTIVES: This study investigated proteolytic, amylase and lipase activities in the intestine of Sparidentex hasta captured from the Persian Gulf. METHODS: 60 immature S...
