Phenolic Acid Utilizing Microbial Populations In Soils And Rhizosphere

Unfortunately there are only limited data available on soil microbial populations that can utilize phenolic acids as a carbon source. The CFU/g soil ranged from 104 to 1010 for bacteria in phenolic acid enriched air-dried soil and not enriched field soils (Table 3.1). However, these numbers of active, quiescent, and/or dormant individuals represent only a small fraction of the bacteria in these soils, since < 1% of the viable bacteria in soils can be cultured.43 The assumption is that the CFU based on cultures are representative or consistently related to the total phenolic acid utilizing microorganisms in the soil.
