Ultrastructural Characterization of Marine Chlorellae. I. Chlorella ovalis

Botanica Marina, 1980
The 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.

Ultrastructural Characterization of Marine Chlorellae. II. Chlorella stigmatophora

Botanica Marina, 1980
The 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. ©

Production of Protein and Lipid by Chlorella vulgaris and Chlorella pyrenoidosa

Journal of Pharmaceutical Sciences, 1963
Cultures 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.

Centrioles and Microtubules in Chlorella

Nature New Biology, 1971
IN 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, 1952
ON 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.

Ammonium uptake by Chlorella

Planta, 1986
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.
