Abstract Lignocellulosic biomass wastes are abundant resources that usually valorized for methane-rich biogas via anaerobic digestion. Conversion of lignocellulose into volatile fatty acids (VFA) rather than is attracting attention due to the higher value-added products come with VFA utilization. This review consolidated latest studies associated characteristics lignocellulosic biomass, effects...

Digestion of crude membrane preparations with papain releases the extracellular portion of major histocompatibility complex (MHC) class I molecules. MHC class I molecules are integral membrane glycoprotein complexes formed by the noncovalent association of 2 invariant molecules, the heavy chain and the beta2-microglobulin (beta2-m), to a wide array of peptides. The cleaved soluble moiety retain...

A microwave-assisted digestion method for the determination of cadmium (Cd) and lead (Pb) by inductively coupled plasma mass spectrometry (ICP-MS) was optimised on certified reference material (CRM) (bovine liver, BCR-185R) and wolf liver samples. Different factors influencing digestion efficiency (temperature, time, composition of the digestion mixture, sample mass) were tested. Validation inc...

While foraging models of terrestrial mammals are concerned primarily with optimizing time/energy budgets, models of foraging behaviour in marine mammals have been primarily concerned with physiological constraints. This has historically centred on calculations of aerobic dive limits. However, other physiological limits are key to forming foraging behaviour, including digestive limitations to fo...

In the elderly, oral functions are modified by changes in muscular force or saliva production among others, resulting inadequate food fragmentation which potentially impacts on and gastrointestinal digestion. The purpose of this work was to evaluate consequences deficiencies starch protein digestibility bread. vitro boluses were prepared with AM2 masticator using normal deficient mastication pr...

This work investigated the potential of generating biogas from mono-digestion various substrates such as food and fruit waste (e.g., durian shell, dragon peel pineapple peel) co-digestion in different combinations a co-substrate well types (durian peel). The mixture ratio varied follows: 75:25, 50:50 25:75, which was based on weight. batch experiments were carried out using 125 ml anaerobic dig...

introduction: helicobacter pylori (h. pylori) infection has remained as a global health problem. animal studies demonstrated the role of h. pylori oipa gene in the development of gastric cancer. the aim of this study was the cloning and expression of helicobacter pylori oipa gene in a bicistronic vector harboring mice il-18 gene. materials and methods: the target gene encoding oipa was amplifie...

Effects of different pretreatment methods on sludge dewaterability and polycyclic aromatic hydrocarbons (PAHs) degradation during petrochemical sludge anaerobic digestion were studied. Results showed that the total biogas production volume in the thermal pretreatment system was 4 and 5 times higher than that in the ultrasound pretreatment and in the control system, and the corresponding volatil...

The large intact prey ingested by Burmese pythons require considerable processing by the stomach before passage into the small intestine. To investigate the function and cost of gastric digestion and its contribution to postprandial metabolic response for the Burmese python, I examined the rate of gastric digestion, the postprandial profile of gastric pH and the effects of decreasing gastric wo...

A dynamic mathematical model of the digestion of proteins in the small intestine of pigs was developed. The model integrates current knowledge on the transit of digesta along the small intestine, endogenous secretions, digestion of proteins, and absorption of amino acids into a mechanistic representation of digestion. The main characteristics of the model are the following: the small intestine ...
