Bacterial-sewage derived biomarkers in sediment core from the Muar River, Malaysia were extracted and analyzed using Gas Chromatography-Mass Spectrometry (GC-MS). It was analyzed in order to understand and elucidate changes in organic matters due to the diagenetic process In this study, a set of fatty alcohol data which contained C15, C15-branched chain, C17 and C17-branched chain together with a couple of sewage sterol, coprostanol and its epimer epi-coprostanol were chosen to be interpreted. The analyzed result showed that sterol concentration is higher compared to fatty alcohol, which varied from 6.62 to 11.60 ng/g dry weight while fatty alcohol concentration ranged from 0.00 to 4.92 ng/g. All these data were used to run a multivariate statistical analysis (Principal Component Analysis-PCA) in order to get a better approach in distinguishing microbial communities. The PCA showed that there are two types of microbial communities present in the sediment core. [ABSTRACT FROM AUTHOR] |
