Effects of Microbial Utilization of Phenolic Acids and their .
Reversible sorption of phenolic acids by soils may provide some protection to phenolic acids from microbial degradation. In the absence of microbes reversible sorption 35 days after addition of 0.5–3 μmol/g of ferulic acid or p-coumaric acid was 8– 4% in Cecil Ap horizon and 3 –38% in Cecil Bt horizon soil materials. The reversibly sorbed/solution ratios r/s for ferulic acid or p . ,Benefits of Citrate Over EDTA for Extracting Phenolic Acids . Benefits of Citrate Over EDTA for Extracting Phenolic Acids from Soils and Plant Debris Blum Udo 2004-09- 2 00:00:00 Journal of Chemical Ecology Vol. 23 No. 2 997 BENEFITS OF CITRATE OVER EDTA FOR EXTRACTING PHENOLIC ACIDS FROM SOILS AND PLANT DEBRIS UDO BLUM Department of Botany North Carolina State University Raleigh North Carolina . ,Benefits of Citrate Over EDTA for Extracting Phenolic Acids . The effectiveness of various citrate extractions to recover ferulic acid a phenolic acid from Cecil Ap and Bt soil and plant surface debris crimson clover rye subterranean clover and wheat was compared with that of EDTA extractions. Citrate extractions were equivalent to or better than EDTA in recovering phenolic acids from soil and plant debris. Citrate unlike EDTA did not interfere .
