Photosynthetic Microorganisms: Cultivation and Application

Continuous cultivation of photosynthetic microorganisms: Approaches, applications and future trends.

The possibility of using photosynthetic microorganisms, such as cyanobacteria and microalgae, for converting light and carbon dioxide into valuable biochemical products has raised the need for new cost-efficient processes ensuring a constant product quality. Food, feed, biofuels, cosmetics and pharmaceutics are among the sectors that can profit from the application of photosynthetic microorgani...

Photosynthetic Microorganisms and Valuable Products

From Chinese Cabbage and Photosynthetic Microorganisms

Ribulose-1,5-diphosphate carboxylase (carboxydismutase) was prepared from Chinese Cabbage [Brassica petsai (Parl)] and the Km values and molecular weight were determined. These parameters were found to be in good agreement with values reported for this enzyme from other higher plants. Investigation of carboxydismutase activity from the photosynthetic micro-organisms Chlamydomonas reinhardi (IU ...

Photoregulated carotenoid biosynthesis in non-photosynthetic microorganisms.

Photoregulated carotenoid biosynthesis consists of an initiating photoactivation which bestows carotenogenic competence upon photochromogenic microorganisms. Subsequent carotenoid biosynthesis is light independent but requires microbial growth. Experimental systems have been developed for several photochromogcnic microorganisms to separate the primary photoact from the following carotenogenic r...

Adaptation and acclimation of photosynthetic microorganisms to permanently cold environments.

Persistently cold environments constitute one of our world's largest ecosystems, and microorganisms dominate the biomass and metabolic activity in these extreme environments. The stress of low temperatures on life is exacerbated in organisms that rely on photoautrophic production of organic carbon and energy sources. Phototrophic organisms must coordinate temperature-independent reactions of li...
