“…They may also be derived from other constituents, such as faeces and plant cells. Amino sugars, major components of peptidoglycans in bacterial cell walls, are revealed by: the occurrence of acetamide (N6) (Eudy et al 1985) and the presence of amine, amide groups and sugars highlighted by FTIR. Proteinaceous structures are also observed for the HPO fraction of wastewater treatment effluents (by FTIR and Py-GC-MS), and these observations are interpreted as an indicator of intense microbial activity (Drewes and Croue 2002).…”

Understanding the nature of organic matter is a necessary first step in assessing contaminant bioavailability and allowing water supply managers to optimise the treatment train in the aim of providing safe and inexpensive drinking water. This study provides further insight into the composition, structure and functional groups of dissolved organic matter (DOM) (both hydrophobic and hydrophilic) from urban aquatic systems by means of various analytical techniques (DAX-8/XAD-4 fractionation, elemental analysis, UV and FTIR spectroscopies, (13)C and (15)N isotopic analysis, size exclusion chromatography and Pyrolysis-GC-MS). The analytical range chosen for this study constitutes a powerful tool in the characterisation of DOM in urban water. The inclusion of information from one technique to the next might not only serve as a support to each one, but also as a complement. The DOM fraction from treated effluent and, more generally, DOM from urban water (i.e. receiving treated effluent) display a strong hydrophilic characteristic [i.e. low humic substance (HS) content, low SUVA], along with a high distribution in molecular weights observed by SEC and low average molecular weight. Due to the origin of this DOM, proteinaceous structures constitute the main compounds, as observed by FTIR and Py-GC-MS. Such characteristics (i.e. heterogeneity, low average molecular weight and diverse functional groups, which make up a total of N) could explain that DOM from treated effluent displayed a strong reactive potential metals pollutants as previously demonstrated

“…Acetamide has been noted as a pyrolysis product of both bacteria [44] and humic substances [45][46][47]. Acetamide has been shown to be the predominant pyrolysis product of peptidoglycan, a primary component of bacterial cell walls [44].…”

“…As no other chlorophyll-derived compounds, such as pristene or phytadiene, were identified, the pyrrole and derivatives in the B24 sludge pyrolysate were attributed to proteins. Acetamide (N14) may be of protein origin (glycine-containing) [24], or be derived from amino sugars [27]. Indole (N22) and methylindole (N24) are indicators of tryptophane-containing peptides [24], pyridine (N4) and derivatives (N5 and N8) can be attributed to alanine-containing proteins and peptides Table 1 Origin, brief description, and analytical data for the five wastewater sludges (data from ref.…”
