in order to evaluate the effects of chlorella on broiler performance and immune system, an experimentwas performed by using 80 ross 308 male broiler chicks. the experiment was accomplished incompletely randomized design including 5 treatments with 4 replication and 4 observations in eachreplicate. the basal diet was based on corn-soybean meal (control) and without any additives. agraded level o...

The kinetics of the 520 mmu absorption change in spinach chloroplasts and Chlorella vulgaris following a flash from the ruby laser have been determined as follows: rise halftime </= 0.3 x 10(-6) second; rapid recovery halftime = 5 to 6 x 10(-6) second; intermediate recovery halftime = 4 x 10(-4) second (spinach chloroplasts only); slow recovery halftime = 12 to 170 x 10(-3) second, dependent on...

Aposymbiotic polyps of Hydra viridis were infected with one or two of the following strains of Chlorella: the native strain obtained from green H, viridis, and the originally non-symbiotic strains Fs and 211/8p cultured in vitro. Larvae of Artemia served as infecting vectors. Chimeric infections were obtained with two different Chlorella strains cohabiting in the same cells and polyps. In time,...

A novel virus, named Acanthocystis turfacea Chlorella virus (ATCV), that infects endosymbiotic Chlorella algae of the heliozoon Acanthocystis turfacea was isolated from freshwater samples. Electron microscopic analysis of ATCV revealed that the viral capsid has a distinct icosahedral shape with a diameter of 140-190 nm. Filamentous structures extending from some of the virus vertices, which may...

After x-ray irradiation, 13 mutants of Chlorella sorokiniana incapable of using NO(3) (-) as N source were isolated using a pinpoint method. Using immunoprecipitation and Western blot assays, no nitrate reductase was found in five strains while in eight mutants the enzyme was detected. The latter strains contained different patterns of nitrate reductase partial reactions. All isolates were of t...

BACKGROUND The green alga Chlorella contains high levels of proteins, vitamins, and minerals. We previously reported that a chlorella-derived multicomponent supplement increased the secretion rate of salivary secretory immunoglobulin A (SIgA) in humans. Here, we investigated whether intake of this chlorella-derived supplement attenuated the reduced salivary SIgA secretion rate during a kendo tr...

Expansion of urban populations, increased coverage of domestic water supply and sewerage give rise to greater quantities of municipal wastewater. With the current emphasis on environmental health and water pollution issues, there is an increasing discharge of waste water in developing countries. Present technologies in developing countries for treating waste water are not sufficient and cost ef...

Predation was a powerful selective force promoting increased morphological complexity in a unicellular prey held in constant environmental conditions. The green alga, Chlorella vulgaris, is a well-studied eukaryote, which has retained its normal unicellular form in cultures in our laboratories for thousands of generations. For the experiments reported here, steady-state unicellular C. vulgaris ...

Pyruvate, Mercaptopyruvate, Lemna, Spinacia, Pisum, Chlorella, Synechococcus, Rhodopseudomonas Mercaptopyruvate sulfotransferase activity catalyzes the formation of pyruvate from mercapto­ pyruvate in the presence of suitable reagents as acceptor. It was detected in Lemna minor, Pisum sativum, Spinacia oleracea, Chlorella fusca, Synechococcus 6301, and Rhodopseudomonas palustris. Best activity ...
