Improved medium for recovery and enumeration of Pseudomonas aeruginosa from water using membrane filters.

摘要

A modified mPA medium, designated mPA-C, was shown to recover Pseudomonas aeruginosa from a variety of water sources with results comparable to those with mPA-B and within the confidence limits of a most-probable-number technique. Enumeration of P. aeruginosa on mPA-C was possible after only 24 h of incubation at 41.5 degrees C, compared with 72 h of incubation required for mPA-B and 96 h of incubation for a presumptive most probable number.
