The management of anaerobic digestate is important to realize the value waste and enhance whole system sustainability digestion. In this study, phosphorus treatment dirty irrigation water by biochar samples derived from digestion were investigated. biochars further activated steam activation with different duration time KOH introducing ratios; textural properties optimized after aspect characte...

The aim of this study was to determine and compare the digestion kinetics of two fibre sources (lucerne, maize stalk) in different segments of the digestive tract of geese. Sixty Jilin nongan white geese were divided into two groups and fed with a lucerne or maize stalk diet. After 30 days of feeding, all of the geese were fed with Co-EDTA as the marker of liquid digesta, and n-alkane was used ...

Mature Angus steers were intraruminally infused with base to increase ruminal pH. Base infusions, increasing rumen pH from 5.8 to 6.2, did not change duodenal pH but tended to reduce fecal pH. Increased ruminal pH tended to increase digestion of fiber (9 percent) but reduced ruminal digestion of starch by 18 percent (P> .05). Ruminal pH and ruminal starch digestion were negatively correlated (P...

In vitro hydrolysis assays are a key tool in understanding differences in rate and extent of digestion of starchy foods. They offer a greater degree of simplicity and flexibility than dynamic in vitro models or in vivo experiments for quantifiable, mechanistic exploration of starch digestion. In the present work the influence of α-amylase and amyloglucosidase activities on the digestion of maiz...

The technology of anaerobic digestion of organic solid wastes is, in many aspects, mature. Topics such as fundamentals (kinetics, modelling, etc.), process aspects (performance, twoand single-phase systems, wet and dry technologies), digestion enhancement (several pre-treatments), co-digestion with other substrates and its relation to composting technology are examined in this review. Special a...

Water hyacinth (Eichhornia crassipes), an invasive aquatic weed with large biomass production is of socio-economic and environmental concern in fresh water bodies such as the Lake Victoria East Africa. Efforts towards its control removal can be complemented by biogas for use energy source. The co-digestion (WH) ruminal slaughterhouse waste (RSW) has potential to improve from WH through collatio...

Coming out from the growth kinetics, the Gompertz model has been developed and considered as the best one for simulating the biogas production from anaerobic digestion. However, the model has failed to describe the starting point of the process, and no-sense of lag phase constant has been pointed out. Thus, the goal of this study is to develop a new kinetic model of biogas production with meani...

Emulsions stabilized by a mixture of emulsifiers may show tailored functionality depending on the compatibility employed. This was proposed in previous work dealing with distinct lipolysis kinetics citrus pectin (CP) and Tween 80 (TW80) based emulsions. CP provided fast high extent gastric lipid hydrolysis, TW80 presented negligible digestion emulsions mixtures intermediate kinetics. The curren...
