RNA assay as a method of viable biomass determination in the organic fraction of municipal solid waste suspension

Abstract

A method of RNA determination by means of alkaline hydrolysis and UV detection was applied to evaluate the amount of viable biomass during the aerobic biodegradation of the organic fraction of the municipal solid waste suspension. The relative standard deviation of this determination was from 0.7 to 4%. The viable biomass constituted only 9% of the volatile suspended solids in the activated sludge.
