this study investigated the effect of season (wet and dry) on milk composition of the dromedary camel (camelus dromedarius). milk samples representing the wet and dry seasons were analyzed for total solids (ts), fat (f), solids-non-fat (snf), ash, crude protein (cp), nitrogen soluble at ph 4.6 (sn), mineral content (mc) and casein fraction (cnf). camel milk had higher (p<0.05) fat content in th...

Gariss is the most popular stable food for the camel herders who depend on Gariss for the sustainability of their livestock. The objective of the current study is to assess the traditional fermented camel milk (Gariss) prepared by nomadic camel woman herders in AlGadarif State in Butana. It is also meant to improve the quality of camel milk products through sharing knowledge. The samples (n= 19...

Fruit from six genotypes of autumn olive (Elaeagnus umbellate Thunb.); Brilliant Rose, Delightful, Jewel, Natural 1, Natural 2 and Sweet N Tart; were evaluated for fruit quality, phenolic content, carotenoids, antioxidants, antioxidant capacity, and antioxidant enzyme activity. The fruit soluble solids content (SSC), titratable acids (TA), total carotenoids, and total phenolic content varied wi...

UNLABELLED BACKGROUND It is necessary to develop efficient methods to produce renewable fuels from lignocellulosic biomass. One of the main challenges to the industrialization of lignocellulose conversion processes is the large amount of cellulase enzymes used for the hydrolysis of cellulose. One method for decreasing the amount of enzyme used is to recycle the enzymes. In this study, the re...

Two series of catalysts were prepared by sol-gel and microemulsion synthetic procedure (SG and ME, respectively). Each series includes both pure Mg and Zr solids as well as Mg-Zr mixed solids with 25%, 50% and 75% nominal Zr content. The whole set of catalysts was characterized from thermal, structural and surface chemical points of view and subsequently applied to the liquid-phase xylose dehyd...

An acidophilic, sulfur-oxidizing Acidithiobacillus thiooxidans MET bacterium was isolated from anaerobically digested, dewatered sewage sludge. This bacterium showed sulfur-oxidizing ability at both acidic and neutral conditions, and allowed metal leaching even at a high (130 g L(-1)) sludge solids concentration. We found that low metal leaching efficiency at high solids concentration was mainl...
