摘要
Community level physiological profiles (CLPPs) tested with Biolog microplates were studied for a maturity sequence of compost from source-separate collected organic waste and prunings. The composts were 42, 120 and 240 days old. Traditional maturity parameters like microbial biomass, pH and temperature significantly decreased with age. Principal component analysis and discriminant analysis showed distinctly different patterns of carbon source utilisation of the different composts. Five substrates were identified that significantly contributed to the difference in CLPPs.
