Abstract Jams are preparations of fruits whose main preserving agent is sugar. Due to this, health concerns consumers have resulted in a sugar reduction, and its replacement using alternative sweeteners introducing new ingredients enhancing nutritional properties. In this study, four types jams (plum, strawberry, apple, peach), with or without sugar, were prepared two microalgae biomass, Arthro...

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...

A protein-synthesizing system consisting of ribosomes and supernatant of undeveloped Artemia saline embryos is used for assay of mRNA translation and initiation factors. This system contains the components needed for chain elongation but has low levels of mRNA and initiation factors. Exogenous mRNA is readily translated upon addition of high-speed supernatant or ribosomal salt wash of developin...

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 ...

Ribulose 1,5-diphosphate carboxylase was isolated from Euglena gracilis Klebs strain Z Pringsheim, Chlorella fusca var. vacuolata, and Chlamydobotrys stellata, and the subunits from each enzyme were separated and purified by gel filtration on Sephadex G-200 in the presence of sodium dodecyl sulfate. Rabbit antibody was elicited against purified Euglena ribulose 1,5-diphosphate carboxylase whole...

The growth and on-site bioremediation potential of an isolated thermal- and CO₂-tolerant mutant strain, Chlorella sp. MTF-7, were investigated. The Chlorella sp. MTF-7 cultures were directly aerated with the flue gas generated from coke oven of a steel plant. The biomass concentration, growth rate and lipid content of Chlorella sp. MTF-7 cultured in an outdoor 50-L photobioreactor for 6 days wa...

We previously reported that the chlorella virus PBCV-1 genome encodes an authentic, membrane-associated glycosyltransferase, hyaluronan synthase (HAS). Hyaluronan, a linear polysaccharide chain composed of alternating beta1,4-glucuronic acid and beta1, 3-N-acetylglucosamine groups, is present in vertebrates as well as a few pathogenic bacteria. Studies of infected cells show that the transcript...
