Accession numbers NC_014374
Background Acidilobus saccharovorans (strain DSM 16705 / VKM B-2471 / 345-15) is an obligate anaerobic, organotrophic, thermoacidophilic crenarchaeon isolated from a hot spring of Uzon Caldera, Kamchatka, Russia. It grows with a range of pH from 2.5 to 5.8 with an optimum at 3.5 to 4 and a temperature range from 60 to 90 degrees Celsius with an optimum at 80 to 85 degrees Celsius. A. saccharovorans utilizes a wide range of proteinaceous and carbohydrate substrates and cannot grow lithoautotrophically on H2 and CO2. S0 and thiosulfate stimulate growth and are reduced to H2S, but protons cannot serve as electron acceptors, since no H2 is produced during growth in the absence of S0. It encodes numerous hydrolytic enzymes and metabolic pathways necessary for the utilization and complete mineralization of organic substrates in its natural habitat, acidic hot springs. It contains 14 genes encoding esterases and genes encoding a complete beta-oxidation pathway, suggesting the ability of A. saccharovorans to utilize triacylglycerides and longchain fatty acids available from the environment. The wide distribution of A.saccharovorans in acidic hot springs suggest an important role of Acidilobales in microbial communities of such habitats, closing the anaerobic carbon cycle through complete mineralization of organic substrates via S0 respiration.
