Genome Sequence of Hydrogenovibrio sp. Strain SC-1, a Chemolithoautotrophic Sulfur and Iron Oxidizer
Hydrogenovibrio sp. strain SC-1 was isolated from pyrrhotite incubated in situ in the marine surface sediment of Catalina Island, CA. Strain SC-1 has demonstrated autotrophic growth through the oxidation of thiosulfate and iron. Here, we present the 2.45-Mb genome sequence of SC-1, which contains 2,262 protein-coding genes.
Pyrrhotite-bearing tailings were deposited in an impoundment at the Copper mine at Laver in Northern Sweden 1936-1946. Sulphide oxidation has released acidity and metals to the recipient since deposition. Sampling of surface water was performed in a brook draining the tailings impoundment in 1993, 2001 and 2004-05. The dissolved concentration of sulphide associated elements such as Cu, S and Zn...
Based on the JK Drop Weight test and principle of selective crushing, a multicomponent complex ore with its component minerals, i.e., pyrrhotite, sphalerite, quartz, was used to explore impact crushing characteristics relationship between minerals. Results show that order resistance is quartz > pyrrhotite sphalerite. The particle-size-distribution characteristic curve products always “sandwi...
