Summary A rural oriented methodology for the production of the blue green alga Spirulina platensis has been developed and practically evaluated on pilot plant scale (45 m2). The system suggested is almost free of electrical inputs or capital intensive equipment and designed to use maximal manpower. A production rate of 3 kg of dry algae per week can be achieved using 45 m2 area. 相似文献

Glutathione peroxidase (GPx) is the prototypical eukaryotic selenoprotein, with the rare amino acid selenocysteine (Sec) at
the enzyme active site, encoded by the UGA codon in RNA. A DNA virus,Molluscum contagiosum, has now been shown to encode a functional selenium-dependent GPx enzyme. Using modifications of conventional sequence database
searching techniques to locate potential viral GPx modules, combined with structurally guided comparative sequence analysis,
we provide compelling evidence that Se-dependent GPx modules are encoded in a number of RNA viruses, including potentially
serious human pathogens like HIV-1 and hepatitis C virus, coxsackievirus B3, HIV-2, and measles virus. Analysis of the sequences
of multiple viral isolates reveals conservation of the putative GPx-related features, at least within viral subtypes or genotypes,
supporting the hypothesis that these are functional GPx modules. 相似文献

The current study was intended to investigate the cholesterol-lowering potential of the two Lactobacillus rhamnosus probiotic strains, LR 5957 and LR 5897, isolated from ‘dahi’. Cholesterol-lowering ability of both strains was determined in in vitro conditions. For in vivo investigations, the Wistar rats were randomly assigned into five groups and treated with different diets: standard diet (SD), high-cholesterol diet (HCD), HCD with Milk, HCD with LR 5957–fermented milk, and HCD with LR 5897–fermented milk. After 3 months of feeding, different parameters of hypercholesterolemia were measured in blood, feces, liver, and kidney. Both the strains, LR 5957 and LR 5897, showed the ability to grow in the presence of cholesterol and eliminate the cholesterol under in vitro conditions. In vivo results indicate that consumption of probiotic-fermented milk has significantly reduced the HCD-induced body weight, hyperlipidemia, and hepatic lipids (total cholesterol and triacylglycerol). Further, increased cholesterol excretion in feces was also observed in probiotic-fed groups. The studied fermented milk also helped to maintain healthy liver and kidney by increasing the antioxidant activities and decreasing the lipid peroxidation. Consumption of probiotic-fermented milk also found to decrease the mRNA expression of the inflammatory markers TNF-α and IL-6 in the liver. Overall, our results indicate that the L. rhamnosus strains, LR 5957 and LR 5897, are two potential probiotic strains that can ameliorate the diet-induced hypercholesterolemia. 相似文献
