Cow dung is generally used as the feedstock material for anaerobic digestion to produce biogas. A selection of alternate biomass needed reduce consumption or eliminate use cow dung. Recently, cottonseed hull has been considered primary substrate In this paper, effect biogas production on co-digestion CD with pre-treated CSH using sulfuric acid, hydrochloric hydrogen per oxide, and acetic acid i...

A simple, efficient and cost effective method was developed and optimized for the digestion of fish tissue for the determination of Lead, Cadmium, Mercury, Antimony, Arsenic and Selenium by FAAS, CVAAS and HGAAS. Three of the more common classical open tubed acid digestion procedures were explored with the purpose of optimizing the variables and selecting the single most efficient, convenient a...

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...

a digestion trial using cannulated lactating cows was conducted to evaluate the influence of barley grain processing on characteristics of ruminal fermentation and the site and extent of digestion. the experiment consisted in 4 periods and lasted 84 days. the total mixed rations contained 39.86% of grains and 42.90% of alfalfa hay and the rest of ration was composed mainly by cane molasses, fat...

A search for alternatives economically viable and environmentally sound to the world energy demand, stimulated research in field of anaerobic digestion, as a form renewable co-digestion is an alternative use different types residues, including food wastes. Therefore, this article presents analysis scientific advances realized period 2015 2018 terms co-digestion, with emphasis on especially frui...

The aim of this study was to investigate the amino acid (AA) release from breads enrichment with edible insects, Alphitobius diaperinus and Tenebrio molitor or pea protein during in vitro gastrointestinal digestion. Bread enriched at 5 10% insect flour protein. Enriched control were subjected standardised static free AAs before after each phase digestion (gastric, intestinal end digestion) dete...
