Effect of Inoculum Concentration on the Degradation of Diesel 2 by a Microbial Consortium

The objective was to determine the effect of inoculum concentration on degradation Diesel 2 by a microbial consortium called BIOT.PD001. For this, five systems were designed (in triplicate), which Contained Davis Minimum Medium, 5% as carbon source, and suspension BIOT.PD001 (9 × 108 cells/mL) in concentrations 2, 4, 6, 8, 10% final volume. monitoring carried out indirectly through bacterial counts plate count method, Biochemical Oxygen Demand (BOD5) Winkler Method modified according Alsterberg, total fats Gerber’s method. retention time 15 days. It observed that percentage efficiency process increases increases, obtaining highest (94.77%) when using (v/v), while 4% percentages are lowest, (68.4 66.6%, respectively). On other hand, variance analysis indicated there is significant difference between averages these values. regression significantly affects this 86% explained linear model. There relationship BOD5 tend decrease function time. concluded consortium.
