New strategies for metabolic engineering of extremely thermophilic microorganisms to produce bio-based fuels and chemicals could leverage pathways and physiological features resident in extreme thermophiles for improved outcomes. Furthermore, very recent advances in genetic tools for these microorganisms make it possible for them to serve as metabolic engineering hosts. Beyond providing a highe...
The host-vector system for an extreme thermophile, Thermus thermophilus HB27, was developed. The host strain has a mutation in tryptophan synthetase gene (trpB), and the mutation was determined to be a missense mutation by DNA sequence analysis. A Thermus-E. coli shuttle vector pYK109 was constructed. pYK109 consists of Thermus cryptic plasmid pTT8, tryptophan synthetase gene (trpB) of Thermus ...
Experimental evolution via continuous culture is a powerful approach to the alteration of complex phenotypes, such as optimal/maximal growth temperatures. The benefit of this approach is that phenotypic selection is tied to growth rate, allowing the production of optimized strains. Herein, we demonstrate the use of a recently described long-term culture apparatus called the Evolugator for the g...
The holm oak woodlands as ecotonic phytocoenoses occur under different ecological conditions, and frequently representing the climax of edaphoxerophilous series crests siliceous rocky areas. In this paper we study floristic, ecological, biogeographical differences southwestern Iberian Peninsula, included in Querco rotundifoliae-Oleenion sylvestris suballiance. Our phytosociological (Braun–Blanq...
The crystal structure of 3-isopropylmalate dehydrogenase from the moderate facultative thermophile Bacillus coagulans (BcIPMDH) has been determined by the X-ray method. BcIPMDH is a dimeric enzyme composed of two identical subunits, each of which takes an open alpha/beta structure with 11 alpha-helices and 14 beta-strands. The polypeptide is folded into two domains. The first domain is composed...
In order to enrich the phylogenetic diversity represented in the available sequenced bacterial genomes and as part of an "Assembling the Tree of Life" project, we determined the genome sequence of Thermomicrobium roseum DSM 5159. T. roseum DSM 5159 is a red-pigmented, rod-shaped, Gram-negative extreme thermophile isolated from a hot spring that possesses both an atypical cell wall composition a...
