Fig. 4From: Bacillus aryabhattai TFG5-mediated synthesis of humic substances from coir pith wastesFT-IR spectra of phenols from the CWW treated with B. aryabhattai TFG5. FTIR peaks of the transformed products of control-sterilized and filter-sterilized CWW are presented. The presence of additional peaks for sterilized phenols is indicated by arrowsBack to article page
