background: long-term extraction and production of various oil derivatives causes contamination of soil adjacent to production and refining area. the main important issue is the ecological hazard of these pollutants. the main aim of the study was to identify and separate native bacteria that are responsible for degradation of oil contaminated fields. methods: we prepared a compound sample of co...

The design of most-probable-number (MPN) experiments is restricted by the availability and completeness of tables for certain dilution ratio and replicate number combinations. The results presented in this paper are from a computer program, the Most Probable Number Enumeration System (MPNES), which generates solutions and confidence limits (P = 0.05) for population estimates of MPN data. Tables...
