2-Propanol degradation by Sulfolobus solfataricus
Biotechnology Letters, 2003Sulfolobus solfataricus used 2-propanol and 2-propanone (acetone) when grown in static cultures at 78 degrees C with or without glucose at 10 g l-1. The presence of 3.92 g 2-propanol l-1 in both cases inhibited growth. However, acetone accumulation following 2-propanol depletion suggested that 2-propanol was co-metabolized via the acetone metabolic ...

Population ecology of Sulfolobus acidocaldarius
Archives of Microbiology, 1974Optimal temperatures for elemental sulfur oxidation were determined for Sul/olobus acidocaldarius populations in a variety of hot, acid springs in Yellow- stone National Park, Wyoming. Cultures were obtained from some of the springs by enrichment and isolation at different incubation temperatures, and the optimal temperatures for these were also ...

Sulfolobus genome: from genomics to biology
Current Opinion in Microbiology, 1998Major progress in sequencing the genome of Sulfolobus solfataricus has been closely concerted with the characterization and sequencing of many extrachromosomal genetic elements, including viruses, cryptic plasmids and conjugative plasmids, as well as mobile archaeal introns and transposons.

The α-l-fucosidase from Sulfolobus solfataricus
Extremophiles, 2007Glycoside hydrolases form hyperthermophilic archaea are interesting model systems for the study of catalysis at high temperatures and, at the moment, their detailed enzymological characterization is the only approach to define their role in vivo. Family 29 of glycoside hydrolases classification groups alpha-L-fucosidases involved in a variety of ...

Our work on Sulfolobus originally arose out of a determination to find a natural habitat for Thermoplasma. As discussed in the previous chapter, Thermoplasma was originally discovered as an acidophilic thermophile living in self-heated coal refuse piles.

The Prefoldin of the Crenarchaeon Sulfolobus solfataricus
Protein & Peptide Letters, 2008Prefoldin is a hetero-hexameric ATP-independent chaperone, shared by eukaryotes and archaea, which binds non-native proteins preventing them from aggregation. We report the identification and characterization in vivo and in vitro of the first prefoldin from a crenarchaeon, the hyperthermophile Sulfolobus solfataricus.

The phosphotriesterase PTE, identified in the soil bacterium Pseudomonas diminuta, is thought to have evolved in the last several decades to degrade the pesticide paraoxon with proficiency approaching the limit of substrate diffusion (k(cat)/K(M) of 4 x 10(7)M(-1)s(-1)).

ADP-Ribosylating Activity in Sulfolobus solfataricus
1989The thermophilic microorganism Sulfolobus solfataricus is able to grow at low pH (3.5) and high temperature (87°C) and has been isolated from an acidic hot spring in Agnano (Napoli), Italy (1). This bacterium belongs to the archaebacteria, a phylogenetic group of microorganisms that can be distinguished from other bacteria and eukaryotes (2, 3).

A defined cultivation medium for Sulfolobus acidocaldarius
Journal of Biotechnology, 2019The thermoacidophilic Crenarchaeon Sulfolobus acidocaldarius is an important model organism for Archaea and genetic systems are well established. To date, the organism is routinely cultivated on complex media based on protein hydrolysates and no common defined medium is established. In this work we address this lack of a standardized defined medium and

Stringent control in the archaeal genus Sulfolobus
Research in Microbiology, 2004Six Archaea belonging to the phylum Euryarchaeota were previously analyzed with respect to stringent control. Only one of the strains studied was shown to possess Bacteria-like stringent control over stable RNA accumulation; ppGpp and pppGpp production was totally lacking in all Archaea analyzed.
