Pseudomonas putida has a variety of potential uses in bioremediation and biosynthesis of biodegradable plastics. P. putida is able to utilize a wide range of carbon sources. In this study, P. putida KT2440 was grown on glucose, glycerol, citrate, or fatty acid (lauric acid) as the sole carbon source. Differences in expression levels of genes involved in the Entner-Doudoroff pathway, glycerol me...

Pseudomonas sp. 61-3 accumulates a blend of poly(3-hydroxybutyrate) [P(3HB)] homopolymer and a random copolymer, poly(3-hydroxybutyrate-co-3-hydroxyalkanoate) [P(3HB-co-3HA)], consisting of 3HA units of 4-12 carbon atoms. Pseudomonas sp. 61-3 possesses two types of PHA synthases, PHB synthase (PhbC) and PHA synthases (PhaC1 and PhaC2), encoded by the phb and pha loci, respectively. The P(94 mol...

Polyhydroxybutyrate (PHB) is a carbon and energy reserve polymer in various prokaryotic species. We determined that, when grown with mannitol as the sole carbon source, Bradyrhizobium diazoefficiens produces a homopolymer composed only of 3-hydroxybutyrate units (PHB). Conditions of oxygen limitation (such as microoxia, oxic stationary phase, and bacteroids inside legume nodules) were permissiv...

The second issue of Molecular Biotechnology offers us a variety of interesting topics ranging from basic science to industrial applications. The current strength of the field and this new journal come into conjunction when we verify how close new genomic tools and commonly used products really are. Indeed, it would not be outrageous to say that we can taste the flavours and sense the aroma of m...
