Background: Bioactive compounds such as terpenoids, chondroitin sulfate, and polysaccharides with added value can be found in prestine marine creatures. These compounds often do have highly valuable therapeutic applications such as being antioxidant, antitumorogenic, anti-infl ammatory and anti-angiogenic. For the latter, varieties of angiogenesis factors can suppress this issu...

The performance of extracted coagulant from the sugarcane bagasse was tested using synthetic wastewater for turbidity removal. Sugarcane selected because it is available in abundance as a waste. This study carried out to analyze effect extraction process optimizing active agent natural optimum Bagasse characterized terms physical, chemical and morphological properties. results showed has very h...

Bacteroides fragilis produces a capsular polysaccharide complex (CPC) that is directly involved in its ability to induce abscesses. Two distinct capsular polysaccharides, polysaccharide A (PS A) and PS B, have been shown to be synthesized by the prototype strain for the study of abscesses, NCTC9343. Both of these polysaccharides in purified form induce abscesses in animal models. In this study,...

Two Bacillus species were studied which produced bioemulsifiers; however, they were distinctly different compounds. Bacillus sp. strain IAF 343 produced unusually high yields of extracellular biosurfactant when grown on a medium containing only water-soluble substrates. The yield of 1 g/liter was appreciably better than those of most of the biosurfactants reported previously. This neutral lipid...

the alginate was extracted with six different methods from iran south seacoast algae, sargassum sp, and the percentage yield of alginate was determined. we divided our methods to two groups including acidic extraction and non-acidic. in acidic methods, hcl and h 2 so 4 were used as a detergent in extraction process and cacl 2 was exerted in non-acidic treatments. all treatments compared with ea...

It is now recognized that adsorption using low-cost adsorbents is an effective and economic method for water decontamination. Chitosan is derived by deacetylation of the naturally occurring biopolymer chitin which is the second most abundant polysaccharide in the world after cellulose. In this study, the capacity of the chitosan nanoparticles was studied for the removal of the anionic Congo red...

Dextran is one of the by-products of sour-storage rot of sugar cane (Egan, 1971). The presence of dextran in cane juice entering the mill has many deleterious effects on raw sugar processing and quality (Foster, 1969a,b; Henderson, 1971; Foster and Wright, 1969; Leonard and Richards, 1969). Hence, the removal of the polysaccharide from juice may alleviate these effects. Physico-chemical methods...

The ability of Trametes villosa laccase, in conjuction with 1-hydroxybenzotriazole (HBT) as mediator and alkaline extraction, to remove lignin was demonstrated during treatment of wood (Eucalyptus globulus) and non-wood (Pennisetum purpureum) feedstocks. At 50 Ug(-1) laccase and 2.5% HBT concentration, 48% and 32% of the Eucalyptus and Pennisetum lignin were removed, respectively. Two-dimension...

In previous experiments in adult rats (Slack, 1954, 1955), massive tissue atrophy was induced by denervation and femoral head dislocation of one hind limb. A study of the metabolism of total collagen, total sulphated polysaccharide, and mixed muscle protein indicated that disuse atrophy does not imply cessation of all protein or polysaccharide synthesis. After the onset of atrophy some synthesi...
