Hydrogen metabolism in blue-green algae
Biochimie, 1978This manuscript reviews the literature on hydrogen metabolism in blue-green algae and reports some new data from this laboratory. H2-formation by intact cells is found to be catalyzed exclusively by nitrogenase. Its rate appears to be variable from strain to strain used byt is--in our hands--very small.

THE HETEROCYSTS OF BLUE‐GREEN ALGAE (MYXOPHYCEAE)
Biological Reviews, 1975Summary1. Heterocysts are found in many species of filamentous blue‐green algae. They are cells of slightly larger size and with a more thickened wall than the vegetative cells.2. Structural details of the heterocyst are: the presence of three additional wall layers, the absence of granules, sparse thylakoid network throughout, except at the poles ...

Blue-green algae, or Cyanophyta (cyan = blue; phyton = plant), are found in a wide variety of environments. They occur in marine and fresh water, on and in soil, and on wet stones, cement, and plant pots. Some can withstand the temperatures of hot springs, others the cold of arctic pools.

The blue-green algae represent a unique stage in the evolution of plant life. The cyanophyta are clearly procaryotic organisms and so they might well be called blue-green bacteria. However they are the only procaryotes able to produce oxygen from water so their photosynthetic activity is like that of the higher plants (Krogmann, 1973).

Control of sporulation in a blue-green alga
Developmental Biology, 1965Abstract Sporulation of the blue-green alga Anabaena cylindrica Lemm. generally ensues adjacent to heterocysts, in strings of from one to several cells. As a preliminary to an attempt to test whether heterocysts help to initiate sporulation of cells adjacent to them, environmental conditions conducive to rapid, sure sporulation adjacent to ...

NADH oxidase in Blue-Green algae
Biochemical and Biophysical Research Communications, 1968Abstract Although particulate fractions prepared from two colorless members of the Cyanophyta were shown by Webster and Hackett (1966) to possess NADH oxidase, it was recently reported that no NADH oxidase activity could be detected in particles isolated from some pigmented members of the Cyanophyta ( Smith et al. , 1967 ).

Effect of pesticides on blue-green algae
Archiv f�r Mikrobiologie, 1973Effect of pesticides, i.e., Benzene Hexachloride, Lindane, Diazinon and Endrin that are often used in India was observed on nitrogen-fixing blue-green algae Cylindrospermum sp., Aulosira fertilissima Ghose and aerobically non-nitrogen-fixing blue-green alga Plectonema boryanum strain 594.
