Mediated biochemical oxygen demand biosensors for pulp mill wastewaters

Trosok, Steve Peter Matyas. January 2000 (has links)
Mediated microbial sensors utilizing two different yeast isolates (SPT1 and SPT2) were developed for the estimation of biochemical oxygen demand (BOD). Measurements of glucose/glutamic acid (GGA) standard solution with potassium ferricyanide mediation resulted in linear ranges extending from the detection limits (i.e. 2 and 5 ppm BOD) to 100 and 200 ppm BOD for the SPT1- and SPT2-based sensors, respectively. The standard error of the mean (SEW for 10 ppm. BOD measurements was 10.1% (SPT1) and 3.9% (SPT2). Response reproducibility had 10.6% error between three identically prepared SPT1 sensors. Response times for concentrations of 20 ppm BOD were within 10 minutes. For pulp mill effluent, the detection limits were 2 (SPT1) and 1 (SPT2) ppm BOD, with SEMs of 3.6% and 14.3% for the SPT1 and SPT2 sensors, respectively. Based on the results obtained in this study, it is concluded that SPT2 is the more suitable biocatalyst for pulp mill wastewater analysis. / While 18S rRNA gene sequence analyses, including BLAST homology searches, have suggested that isolate SPT1 is a close relative of Candida sojae (99.8% homology), no close matches have been found for isolate SPT2. The closest match for SPT2 was to Candida krusei (76.0% homology). Evidence from biochemical tests, fatty acid analysis, and 18S rRNA gene sequence analyses, indicates that isolate SPT2 is a novel yeast species.
