Abstract
Alternative techniques to agar plating methods for enumerating of bacteria and fungi counting have been developed, in order to get faster and simpler techniques without producing any effect on analytical sensibility and precision. The objective of the present study was evaluate the performance of Petrifilm® AC for enumeration of bacteria and of Petrifilm® YM for enumeration of yeasts and molds in ninety samples of herbal drugs, by comparing the enumeration obtained from both Petrifilm® systems, and that one achieved from conventional agar plating methods. Correlation coefficients of 0,9833 and 0,9231 were observed for enumeration of bacteria and fungi respectively. The results suggest that Petrifilm® is suitable as an alternative technique to conventional methods for microorganisms counting.References
