英文摘要	Our findings demonstrated that D. vulgaris surface-adhered populations produce extracellular structures, and that that the cells have altered carbon and energy flux compared to planktonic cells. Biofilms did not have greatly increased carbohydrate accumulation. Interestingly genes present on the native plasmid found in D. vulgaris Hildenborough were necessary for wild type biofilm formation. In addition, extracellular appendages dependent on functions or proteins encoded by flaG or fliA also contributed to biofilm formation. Studies with SRB biofilms have indicated that the reduction and precipitation of metals can occur within the biofilm matrix; however, little work has been done to elucidate the physiological state of surface-adhered cells during metal reduction (Cr6+, U6+) and how this process is affected by nutrient feed levels (i.e., the stimulant).
