TL;DR: The complete genome sequence of A. vinelandii DJ is reported, which identified the chromosomal locations of the genes coding for the three known oxygen-sensitive nitrogenases, as well as genes codes for other oxygen- sensitive enzymes, such as carbon monoxide dehydrogenase and formate dehydrogen enzyme.

TL;DR: Alginates may become useful in applications where reproducible and specific physical properties are required and be used to modify alginates in vitro to obtain polysaccharides with the desired content and distribution pattern of G.

TL;DR: The isolation of four different epimerization-defective point mutants of the periplasmic Pseudomonas fluorescens mannuronan C-5-epimerase AlgG is reported, showing the formation of two distinct classes of polymers in a genetically pure cell line.

TL;DR: It is shown that the Azotobacter vinelandii organism encodes at least four other ME genes originating from a common ancestor gene by a complex rearrangement process, which may explain the origin of the structural variability found in alginates isolated both from prokaryotic and eukaryotic organisms.

TL;DR: The present review extracts main findings from the high number of reports on process optimization for DHA production and interpret these in the light of the current knowledge of DHA synthesis in thraustochytrids and lipid accumulation in oleaginous microorganisms in general.
