1. Digestibility and pricing of Chlorella sorokiniana meal for use in tilapia feeds
ABSTRACT: Several microalgae contain in excess of 50 % crude protein with amino acid profile comparable to that of fish meal. In addition, high polyunsaturated fatty acid contents encourage their use in animal feeding and nutrition, particularly in the formulation and processing of aquafeeds. This study aims at estimating the feasibility of Chlorella meal as

2. Effect of nitrogen limitation on cell growth, lipid accumulation and gene expression in Chlorella sorokiniana
The influence of nitrogen (N) limitation on the cell growth, chlorophyll content, intracellular lipid production and expression levels of two pathway genes in Chlorella sorokiniana was investigated in mixotrophic culture in this study. The maximum biomass concentration of C. sorokinianacultured in modified BG11 medium containing 3, 6, 9, 12 and 15 mM N were

3. Uso de biomassa de algas para a peletização de sementes de Bowdichia virgilioides Kunth
Microalgas são consideradas organismos promissores com aplicações em diversas áreas, entre elas para a fixação de CO2, indústria alimentícia, cosmética e farmacêutica. A industrialização na produção desses organismos levará à geração de resíduos, cuja utilização é vista como contribuinte na redução de custos de produção. Nesta pesqu

4. Effects of Hypobaric and Hyperbaric Helium Atmospheres on the Growth of Chlorella sorokiniana
Growth of Chlorella sorokiniana is unaffected by the choice of atmospheric diluent gas. Reduced total pressure has no inhibitory effect and may be slightly stimulatory.

5. Control of Free Methionine Production in Wild Type and Ethionine-resistant Mutants of Chlorella sorokiniana
Mutants of Chlorella sorokiniana selected for resistance to the methionine analogue ethionine took up ethionine at the same rate as did the wild type strain. Cells of two ethionine-resistant mutants produced severalfold higher levels of free methionine and cysteine than did wild type cells.

6. Ozone-induced Loss of Intracellular Potassium Ion from Chlorella sorokiniana12
The unicellular algae Chlorella sorokiniana was used as a model system to investigate the interaction of ozone with plant cell membranes. Ozone induces K+ leakage from Chlorella sorokiniana similar to the electrolytic loss observed from many higher plants under stressful conditions. The kinetics of this leakage indicate that ozone initially interacts reversi

7. Characterization of Nitrate Reductase Deficient Mutants of Chlorella sorokiniana
After x-ray irradiation, 13 mutants of Chlorella sorokiniana incapable of using NO3− 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

8. Numerical Taxonomy of Heterotrophic Bacteria Growing in Association with Continuous-Culture Chlorella sorokiniana
Twenty-nine cultures isolated from nonaxenic growths of Chlorella sorokiniana (Shihira and Krauss) and eight reference cultures were tested for 150 morphological and biochemical characteristics. The taxonomic data were subjected to computer analysis from which five major clusters were identified. The bacterial isolates have been placed in the genera: Pseudom

9. Ozone Inhibition of Photosynthesis in Chlorella sorokiniana
Exposure of Chlorella sorokiniana (07-11-05) to ozone inhibits photosynthesis. In this study, the effects of ozone on O2 evolution and fluorescence yields are used to characterize this inhibition. At an ozone dose of about 3 micromoles delivered to 2 × 109 cells, the photosynthetic rate of the cells is inhibited 50%, as indicated by a decrease in bicarbonat

11. Growth of Chlorella sorokiniana at Hyperbaric Oxygen Pressures
The growth rate of Chlorella sorokiniana decreased in a linear fashion as the partial pressure of oxygen was increased from 711 to 1,478 mm of Hg. Under two atmospheres of oxygen pressure, growth ceased after 10 to 12 hr. This cessation of growth was not due to any permanent injury, as growth resumed when oxygen partial pressure was reduced to ambient levels

12. A Constitutive Enzyme System for Glucose Transport by Chlorella sorokiniana1
It was found that the transport system for glucose (as measured by deoxyglucose uptake) in the high temperature strain of Chlorella (strain 07-11-05 or C. sorokiniana) was constitutive and the rate of uptake did not increase upon incubation of autotrophically grown cells with either deoxyglucose or glucose. The uptake obeyed Michaelis-Menten type kinetics wi
