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 ...

The maximum quantum yield of oxygen evolution in deuterated chlorella is found to be 0.075, while normal chlorella showed, in parallel experiments, a value of 0.10. Deuterated Chlorella vulgaris showed a decline in the quantum yield of oxygen evolution ("red drop") beginning at 680 millimicrons and a clear Emerson enhancement effect qualitatively similar to that obtained in normal chlorella cel...

For overcoming the long period of seed cultured photoautotrophically and inadequate cell supply for the inoculation of microalgae photoautotrophic cultivation, a model for the photoautotrophic culture of three Chlorella species with heterotrophic cells as seed was investigated. The model can not only take advantages of rapid cell growth in heterotrophic process for preparation of cells as seed ...

BACKGROUND/AIMS To investigate the advantage of Chlorella vulgaris supplementation as an adjunctive therapy in patients with non-alcoholic fatty liver disease (NAFLD). METHODOLOGY In a randomized, open-label clinical trial, 76 individuals with NAFLD were randomly assigned to: 1) Chlorella group (n=33), receiving C. vulgaris extract (1200 mg/day) + metformin (750 mg/ day) + vitamin E (200 mg/d...

Chloroplast NADPH-dependent thioredoxin reductase (NTRC) catalyzes the reduction of 2-Cys peroxiredoxin (2-Cys Prx) and, thus, probably functions as an antioxidant system. The functions of the enzyme in oxidative and salt stresses have been reported previously. We have previously identified and characterized NTRC in Chlorella vulgaris. In the present study, we isolated a full-length cDNA clone ...

To clone the genes encoding lysis protein from a Chlorella virus, water samples were collected from 13 aquatic environments located in the Kanto area of Japan. Eight water samples contained plaque-forming viruses on Chlorella sp. NC64A, but no virus was detected in the other five samples. A novel Chlorella virus, CVN1, was isolated from the Inba-numa marsh sample. CVN1 genomic DNA was partially...

Biofixation of CO2 by microalgae has been recognized as an attractive approach to CO2 mitigation. The main objective of this work was to maximize the rate of CO2 fixation ( [Formula: see text] ) by the green microalga Chlorella vulgaris P12 cultivated photoautotrophically in bubble column photobioreactors under different CO2 concentrations (ranging from 2% to 10%) and aeration rates (ranging fr...

The nutrient removal efficiency of Chlorella vulgaris cultivated in domestic wastewater was investigated, along with the potential to use membrane filtration as a pre-treatment tool during the wastewater treatment process. Chlorella vulgaris was batch cultivated for 12 days in a bubble column system with two different wastewater treatments. Maximum uptake of 94.18% ammonium (NH₄-N) and 97.69% o...

Cheese analogue (Ch A) is processed cheese-like product, a nutritious food, can be healthy and attractive when redesigned to be prepared with the addition of a natural ingredient, being Chlorella vulgaris. This microalga is recognized as a rich source of protein, fatty acids, fiber and ash. C. vulgaris also represents a valuable source of essential vitamins and minerals. Chlorella has health be...

BCF1 (bioconcentration factor after the one day of exposition) value of BaP [benzo(a)pyrene] in strain A-8, Chlorella vulgaris Beijerinck 1890 (Chlorella BB) was studied. The algae were cultured in a modified Kiihl-Lorentzen liquid medium at room temperature, under continuous illumination and stirring for 24
