Preliminary Application

A mercury chloride sensitive Bacillus sp. X4 as a toxicity recognition element was isolated from soil. A novel microbial biosensor was developed based on the isolated X4 in combination with a dissolved oxygen electrode for the analysis of toxicity in wastewater. Optimal response of the biosensor was obtained at pH 7.0 - 7.5 and 30 - 35 °C with a detection linearity over the range 0.10 - 1.97 mg·L-1 of HgCl2. The repeatability of the sensor response were found to be 1.8%. Preliminary application of the biosensor in pharmacy wastewaters has demonstrated their effectiveness. Toxicity values produced with this biosensor for pharmacy wastewaters correlated well with those determined by standard method.

Lower Temperature

The growth and respiration rates of a marine obligate psychrophile, Vibrio sp., were determined in a complex medium using optical density and viable counts and a polarized oxygen-electrode system. Growth rate was optimal at 7C and decreased at 10C, the maximum temperature for growth. Respiration increased continually from 1to 10C. Both growth and respiration rates were highly sensitive to small changes in temperature. For example, rates at 4C were 1.8 and 4.4 times higher than at 1C for growth and respiration, respectively. Growth efficiencies were calculated as generations per hour divided by respiration rate. Results indicated that the growth efficiency of this bacterium was much greater at the lower temperature range of growth.
