Ultrastructural Characterization of Marine Chlorellae. I. Chlorella ovalis
Botanica Marina, 1980The ultrastructure of Chlorella ovalis has been studied. This investigation has allowed to evidence important systematic features as the cup shape of the plastid and the presence of a central pyrenoid in it. Moreover a mitochondrial reticulum and an origin of the Golgi apparatus from the nuclear envelope have been observed.

Production of Protein and Lipid by Chlorella vulgaris and Chlorella pyrenoidosa
Journal of Pharmaceutical Sciences, 1963Cultures of Chlorella vulgaris reach the stationary phase of their growth cycle more slowly than cultures of C. pyrenoidosa when both are provided with conditions favorable for their growth. But after 3 weeks of incubation, the yields from the two organisms are nearly identical in terms of packed volume, dry weight, and cell population.

Ultrastructural Characterization of Marine Chlorellae. II. Chlorella stigmatophora
Botanica Marina, 1980The ultrastructural study of Chlorella stigmatophora has evidenced some interesting features among which the presence of numerous closely packed vacuoles, the poorly reticulated shape of the mitochondrion, and the irregular shape of the plastid with one or more pyrenoids must be remembered. On the contrary, no stigma-like structure could be observed. ©

Centrioles and Microtubules in Chlorella
Nature New Biology, 1971IN keeping with its widespread use in biochemical studies, the ultrastructure of the unicellular green alga Chlorella has been investigated many times1–3, yet at least two components—microtubules and centrioles—have escaped detection, doubtless because of the use of inadequate fixation techniques.

Precursors of Protoporphyrin in Chlorella
Nature, 1952ON the basis of studies of Chlorella mutants a biosynthetic chain has been formulated leading from protoporphyrin through Mg protoporphyrin, Mg vinyl pheoporphyrin and protochlorophyll finally to chlorophyll1. We have recently isolated a Chlorella mutant which promises to reveal some of the precursor porphyrins leading up to protoporphyrin.

The preincubation of Chlorella cells with glucose caused a tenfold increase of the maximal uptake rate of ammonium without change in the K m (2 μM). A similar stimulation of ammonium uptake was found when the cells were transferred to nitrogen-free growth medium. The time-course of uptake stimulation by glucose revealed a lag period of 10-20 min.

International Journal of Dermatology, 1984
ABSTRACT: Swelling followed by erythematopurpuric lesions on sun‐exposed areas of the body developed in five patients. All patients were found to have ingested chlorella. The histopathologic changes consisted of swelling of endothelial cells and thrombosis of small blood vessels in the dermis and the subcutaneous fatty tissue.

Fermentation of glucose by Chlorella
Archiv für Mikrobiologie, 19701. It was confirmed that the colourless alga, Prototheca zopfii converts glucose completely to lactic acid during fermentation. 2. Lactic acid was the only acidic product of glucose fermentation by Chlorella strain 211/1e, 1.4 moles being formed for each mole glucose fermented. This strain produced negligible carbon dioxide and hydrogen;

Arginine utilization by Chlorella autotrophica and Chlorella saccharophila
Physiologia Plantarum, 1990Chlorella saccharophila can utilize the amino acids arginine, glutamate. ornithine and proline as sole sources of nitrogen for growth. By comparison C. autotrophica utilized only arginine and ornithine. Following osmotic shock of Chlorella autotrophica from 50 to 150% artificial seawater rapid synthesis of proline (the main osmoregulatory solute in ...
