A new method to estimate the number of polyhydroxyalkanoates (PHA)-degraders in soil and to isolate degraders, called the film-MPN method, is proposed. The incubation time was measured by the first order reaction (FOR) model. This method was used to estimate numbers of poly (3-hydroxybutyrate-co-3-hydroxyvalerate)[P(3HB-co-3HV)]- and poly(3-hydroxyvalerate-co-4-hydroxybutyrate)[P(3HB-co-4HB)]-degraders in garden soil (4.30 x 10**5 and 2.15 x 10**5 aerobic degraders per gram of dry soil, respectively). The number of P(3HB-co-3HV)-degraders in paddy field soil was 5.06 x 10**5 aerobic degraders per gram dry soil. Also, several P(3HB-co-3HV)-degraders were isolated directly from positive-growth tubes of high dilution.
