Number Of Bacteria

Malate dehydrogenase from a number of bacteria drawn from several genera and representing the mesophilic, moderately thermophilic and extremely thermophilic classes was isolated by procedures which involve only a small number of steps (in most cases only two), of which the key one is affinity chromatography on 5′-AMP–Sepharose and/or on NAD+–hexane–agarose. Electrophoretic analysis of the native enzymes in polyacrylamide gel and of the denaturated enzymes in sodium dodecyl sulphate/polyacrylamide gel revealed no significant protein impurity in the purified preparations. The yields ranged from about 40% to over 80%. The malate dehydrogenases from the extreme thermophiles and from some of the moderate thermophiles are appreciably less efficient catalytically than their mesophilic homologues.

Moderate Thermophiles

Microorganisms with the capability to desulfurize petroleum are in high demand with escalating restrictions currently placed on fuel purity. Thermophilic desulfurizers are particularly valuable in high-temperature industrial applications. We report the whole-genome sequences ofPaenibacillus napthalenovorans32O-Y andPaenibacillussp. 32O-W, which can and cannot, respectively, metabolize dibenzothiophene.

Sulfur Oxidizing

Novel iron- and sulfur-oxidizing, moderate thermophiles were isolated from an acidic geothermal site and from a previously studied, pyrite-enrichment mixed culture (which also contained the related actinobacterium Acidimicrobium ferrooxidans). The novel species (proposed genus “Acidithiomicrobium”) grew autotrophically with ferrous iron at an optimum temperature of about 50°C, efficiently degraded pyrite at 55°C and also grew well autotrophically on sulfur. The extensive dissolution of pyrite during autotrophic growth contrasted with a requirement for yeast extract for significant growth of the related Acidimicrobium ferrooxidans.
