Abstract
To understand the effect of daily bioaugmentation in fullscale grease interceptors GIs we compared the microbial communities occurring in two fullscale GIs during bioaugmented and nonbioaugmented cycles The changes in microbial communities were determined using terminal restriction fragment length polymorphism TRFLP and 16S rRNA gene clone library construction Differences in the microbial community structure between control and bioaugmented cycles were observed in all cases although the dominant terminal restriction fragments in the biological product were not detected The addition of bioaugmentation products and changes in the GI microbial ecology were related to differences in GI performance Understanding the shifts due to bioaugmentation will result in more informed assessments of the benefits of bioadditives on FOG removal in GIs as well as the effects on downstream sewer linesThis project was supported by a research grant from the Consumer Specialty Products Association CSPA CSPA also provided biological products used in the study based on a blind experimental design CSPA did not know which product was used in which experiments CSPA was not involved in experimental design data collection data analysis and manuscript preparation
