' carbon sources or nutrients added. Triplicate plates were inoculated with 1.0 ml of a 0.2%sodium <br /> ' pyrophosphate extract of sample at log dilutions 10', 10', 10', 10-6and 10-7. The heterotrophic <br /> plates were counted after 3 days of incubation at 30°C. The plate count data are reported as colony <br /> forming units (cfu)per gram (g). Each enumeration value represents a statistical average of the <br /> plate count data obtained from two of the four inoculating log dilutions assayed. <br /> ' AEROBIC <br /> Hydrocarbon-Degrading and Total Heterotrophic Bacteria <br /> Enumeration Assa Results <br /> Client Sample Sample Hydrocarbon Target Total <br /> Number Date Degraders Hydrocarbons Heterotrophs <br /> cfu/ Tested cfu/ <br /> ' CT-mw-9- <br /> 120(115-1165) 6/25/2009 6 x 105 Gasoline/Diesel 7x 106 <br /> ' CT-mw-9- <br /> 120(80-81.5) 6/25/2009 6x 105 Gasoline/Diesel 1 x 10' <br /> Sterile Water 6/26/2009 0 Gasoline/Diesel 0 <br /> Air control 6/26/2009 0 Gasoline/Diesel 0 <br /> Positive Control 6/26/2009 2 x 108 Gasoline/Diesel 3 x 109 <br /> ' Reporting Limit for enumeration data is 1 x 10 cfu/g. <br /> A positive control sample of hydrocarbon-degrading bacteria was run concurrently with these <br /> ' samples using a mixed flask culture of bacteria isolated from contaminated groundwater sites in <br /> Northern California. <br /> achel Dutburt Randa von Wedel,Ph.D. <br /> LaboLaioty Tcx mician Principal Biochemist <br /> C:\CytoCulture2009\Cytolab\Lab reports\PSClndusnialOutsourcing.LP\Soil 09-151 <br /> ' 2 <br />
