Effect of temperature control on green algae grown under continuous culture

The effect of low temperature on Antarctic endolithic green algae.

Laboratory experiments show that undercooling to about -5 degrees C occurs in colonized Beacon sandstones of the Ross Desert, Antarctica. High-frequency temperature oscillations between 5 degrees C and -5 degrees C or -10 degrees C (which occur in nature on the rock surface) did not damage Hemichloris antarctica. In a cryomicroscope, H. antarctica appeared to be undamaged after slow or rapid ...

EVALUATION OF BLUE GREEN ALGAE GROWN UNDER DIFFERENT pH CONDITION FOR BIOFUEL PRODUCTION

Blue green algae was isolated from fresh water bodies of Allahabad region, Yamuna River, India to produce biodiesel. Based on rate of growth in cultural media and morphological characters and biomass production, 8 colonizing blue green algae isolates were selected for the further biofuel production work. To further narrow down the number of isolates, the carbonic anhydrase enzyme assay was used...

The nutritional value of algae grown under different culture conditions for Mytilus edulis L. larvae

Continuous cultures of Skeletonema costatum, Chaetoceros muelleri, Rhinomonas reticulata and PaÕloÕa lutheri were subjected to phosphorus or nitrogen limitation at two light intensities in order to manipulate their biochemical composition. They were then fed to Mytilus edulis larvae over a 2-week period, and the larval growth and mortality were assessed. All monospecific diets supported growth,...
