ADAPTATION OF SELENASTRUM CAPRICORNUTUM (CHLOROPHYCEAE) TO COPPER

Environmental Toxicology and Chemistry, 1986
Abstract Selenastrum capricornutum Printz, growing in a chemically defined medium, was used as a model for studying adaptation of algae to a toxic metal (copper) ion. Cells exhibited lag-phase adaptation to 0.8 μM total Cu (10−12 M free ion concentration) after 20 generations of Cu exposure.

Conditional senescence in Chlamydomonas reinhardtii (Chlorophyceae)

Journal of Phycology, 2013
The mechanisms of microalgal senescence may play an important role in nutrient recycling and enhanced survival. However, the aging physiology of microalgae is an understudied phenomenon. To investigate the patterns of conditional senescence in Chlamydomonas reinhardtii P. A. Dangeard, we used a cell wall‐less strain, transformed with a reporter gene to

Detection of green algae (Chlorophyceae) for the diagnosis of drowning

International Journal of Legal Medicine, 1995
The plankton test (generally, diatom test) is one of the methods available to diagnose the cause of death of submerged bodies. The solubilization method using tissue solubilizer Soluene-350 was used in this study to detect not only diatoms but also green algae, based on the fact that the solubilizer does not digest the cell walls of green algae which ...

Pleomorphism inScenedesmus quadricauda (Turp) Bréb. (Chlorophyceae)

Hydrobiological Bulletin, 1976
A clone ofScenedesmus quadricauda, isolated from Tjeukemeer, exhibits a high degree of morphological variation in synchronized cultures. Cells are synchronized by light-dark cycles. During the photoperiod they build up the capacity to divide. First division into 2- and 4-celled coenobia is induced, then during the second half of the photoperiod the ...

INVERSION IN VOLVOX (CHLOROPHYCEAE)1

Journal of Phycology, 1977
ABSTRACTThe asexual embryos of Volvox turn themselves inside out (invert) during development. Data presented indicate that inversion of the embryos is the result of several simple cellular shape changes, coordinated in space and time. Using whole embryos, cell groups and individual embryonic cells isolated by watchmaker's forceps and pressure on the ...
