Chlorella ellipsoidea

The full details of the conversion of cycloeucalenol into [19- H]obtusifoliol by the microsomes of Zea mays in DjO have appeared (see Vol. 7, p. 135). The formation of a A intermediate in the enzymatic cleavage of the cyclopropane ring is excluded by the incorporation of only one deuterium atom. Both cyclo-artenol and lanosterol are converted into normal sterols by Saprolegnia ferax and Chlorella ellipsoidea. ...

Chlorella ellipsoidea was found to be able to convert tritium-labelled 5a-ergosta-8,14-dien-3/3-ol and 4 -methyl-5a-ergost-8-en-3/3-ol into ergost-5-en-3)8-ol, but brassicasterol (ergosta-5,22-dien-3/3-ol) was not labelled,180 and thus it is probably not derived from a saturated side-chain precursor.

Myers and Graham (Ml6) studied the growth of Chlorella ellipsoidea in continuous culture. Their results are not given in such a way that direct comparison with the batch growth data of Tamiya et al. (Tl) is possible however, Myers and Graham found that the productivity at low cell concentrations seemed to be predictable from batch data which they obtained. 

Synchronized cultures of Chlorella ellipsoidea were used as a model system to identify biochemical modes of action of two herbicides/ butamiphos (0-ethyl--0-(3-methyl-6-nitropheny1)-N-sec-buty1-phosphorothioamidate, formerly coded S-2846), and chlorpropham (isopropyl inch lorocarban il ate). Cell cycle studies showed that butamiphos inhibited cell division, whereas its effects on respiration and general biosynthesis were slight. Confirmatory experiments with onion root apices showed that mitosis was blocked at the metaphase and that the spindle apparatus was disrupted. 

This indicated a butamiphos-sensitive period ended around the 17th to 18th h. According to electron microscopic studies by Takabayashi al. ( ), mitosis of Chlorella ellipsoidea starts around the 16th h. 

This protein is found exclusively in the chloroplast where it is involved in electron transfer from Photosystem II to Photosystem I. Plastocyainin has been isolated from a number of green algae Chlorella ellipsoidea 31), and Chlamydomonas rheinhardi 32), as well as from spinach 33), French bean 34), parsley 35), and Chenopodium album 36).

Racemic a-ionone (513) was converted to 4-hydroxy-a-ionone (514), which was further dehydrogenated to 4-oxo-a-ionone (515) by Chlorella ellipsoidea IAMC-27 and C. vulgaris IAMC-209. a-Ionone (513) was reduced preferentially to a-ionol (516) by Chlorella sorokiniana and Chlorella salina (Noma et al. 1997b).
