ABSTRACT
SAR86 denotes a 16S clade of gammaproteobacteria that are ubiquitous in ocean surface waters. So far, SAR86 is resistant to cultivation; thus, little is known about the genome contents or physiology of this clade. Recently, four partial genome sequences for SAR86 subclades I and II were published. Here, we present the draft genome sequence of a single cell from SAR86 subgroup IIIa isolated from coastal waters in San Diego, CA.
ABSTRACT
The complete genome sequence of Geobacter sulfurreducens, a delta-proteobacterium, reveals unsuspected capabilities, including evidence of aerobic metabolism, one-carbon and complex carbon metabolism, motility, and chemotactic behavior. These characteristics, coupled with the possession of many two-component sensors and many c-type cytochromes, reveal an ability to create alternative, redundant, electron transport networks and offer insights into the process of metal ion reduction in subsurface environments. As well as playing roles in the global cycling of metals and carbon, this organism clearly has the potential for use in bioremediation of radioactive metals and in the generation of electricity.
