Genetic Background and Phenotypic Aspects of Light-Induced Carotenoid Biosynthesis in Isosphaeraceae Planctomycetes

Microbiology Research
Nearly half of the currently described planctomycetes display pink, red, or orange pigmentation. Until recently, however, carotenoid biosynthesis in these bacteria remained largely unexplored. We examined the carotenogenesis and its genetic background in

Yeast need not be used only in beer production. I. The carotenoid astaxanthin produced by yeast.

Kvasný průmysl, 2020
Carotenoids are produced by photosynthesizing organisms, i.e. plants and algae, as well as some bacteria, protists and fungi. Their role lies mainly in the function of complementary photosynthetic pigments and antioxidants.

Genomewide characterisation of the genetic diversity of carotenogenesis in bacteria of the order Sphingomonadales

Microbial Genomics, 2018
The order Sphingomonadales is a taxon of bacteria with a variety of physiological features and carotenoid pigments. Some of the coloured strains within this order are known to be aerobic anoxygenic phototrophs that contain characteristic photosynthesis ...

Effects of light intensity and the remaining nitrate concentration on the beta-carotene accumulation of a wild Dunaliella salina strain isolated from the saline soil

Microbiology Research, 2015
An isolated Dunaliella salina strain from northern Thailand was cultured in modified Johnson’s medium in column photobioreactor. The beta-carotene accumulation mainly depended on the quantities of cells entering into carotenogenesis condition that was ...

Carotenogénesis de cinco cepas del alga Dunaliella sp. (Chlorophyceae) aisladas de lagunas hipersalinas de Venezuela

, 2016
We evaluated discontinuous cultures (Algal medium at 0.5 mM of NaNO3, and 27% NaCl) of five strains of Dunaliella sp. isolated from Venezuelan hypersaline lagoons (Araya, Coche, Peonía, Cumaraguas, and Boca Chica) and one strain from a reference ...
