10.22376/ijpbs.2019.10.1.p1-12 Volume 2 Issue 2 2011 (April - June) A comparison is drawn between fungal humic acid produced by lessThan i greaterThan Aspergillus niger lessThan /i greaterThan X lessThan sub greaterThan 1 lessThan /sub greaterThan and soil humic acid regarding elementary and functional groups analysis. Elementary and functional groups analysis show that unhydrolyzed fungal humic acid contained more H and N per unit weight, more alcoholic OH but lower CO lessThan sub greaterThan 2 lessThan /sub greaterThan H and phenolic OH groups than unhydrolyzed soil humic acids. The C and N content of 6(N) HCl hydrolyzed humic acid are higher but the O content lower than the soil humic acids. Acid hydrolysis also increase the content of phenolic groups in fungal humic acid, this is accompanied by a decrease in alcoholic OH groups. There exist a number of similarities in analytical characteristics, especially surface functional groups. N. Ghosh,S. Ganguly And A. K.
