Abstract
Thermus thermophilus HB8 expresses silica-induced protein (Sip) when cultured in medium containing supersaturated silicic acids. DNA microarray analysis suggests that supersaturated silicic acids and iron deficiency affect Thermus cells similarly, and enhances sip transcription is detected under both conditions. Considering that Sip is involved in iron acquisition, Sip production may be a strategy to survive under conditions of low iron availability in geothermal water.
