Relations between Pigment Content and Photosynthetic Characteristics in a Blue-green Alga

1. The blue-green alga Anacystis nidulans was cultured under steady state conditions at 25 and 39 degrees C. and under several different light intensities to give five different types of cells. 2. Cells were submitted to pigment analysis based upon acetone extracts and aqueous extracts obtained by sonic disintegration. The different cell types show a threefold range of chlorophyll content and a...

Some Respiratory Characteristics of the Blue-Green Alga, Anabaena.

In recent years there has been a considerable increase in our knowledge of the respiratory metabolism in higher plants. The lower plants, however, have received little attention. This is particularly true of the blue-green algae where the amount of available information on their respiration is almost negligible. The only known investigation has been that of EMERSON (1) who reported that respira...

Photosynthetic electron transport in a cell-free preparation from the thermophilic blue-green alga Phormidium laminosum.

1. A cell-free preparation of membrane fragments was prepared from the thermophilic blue-green alga Phormidium laminosum by lysozyme treatment of the cells followed by osmotic shock to lyse the spheroplasts. The membrane fragments showed high rates of photosynthetic electron transport and O2 evolution (180-250 mumol of O2/h per mg of chlorophyll a with 2,6-dimethyl-1,4-benzoquinone as electron ...

Phosphorus-limited growth of a green alga and a blue-green alga.

The phosphorus-limited growth kinetics of the chlorophyte Scenedesmus quadricauda and the cyanophyte Synechococcus Nägeli were studied by using batch and continuous culturing techniques. The steady-state phosphate transport capability and the phosphorus storage capacity is higher in S. Nägeli than in S. quadricauda. Synechococcus Nägeli can also deplete phosphate to much lower levels than can S...

Photosynthetic Reactions by Lysed Protoplasts and Particle Preparations from the Blue-Green Alga, Phormidium luridum.

Reactions of photosynthetic electron transport and photophosphorylation were studied in preparations from the blue-green alga, Phormidium luridum. Osmotic lysis of protoplasts proved to be a superior technique for the production of cell-free preparations with high enzymatic activity. Such lysed protoplasts sustain high rates of photophosphorylation coupled to the photo-reduction of NADP(+) or f...
