| Title | PHA production by mixed cultures: A way to valorize wastes from pulp industry |
| Abstract | In this work, hardwood spent sulfite liquor (HSSL), a complex feedstock originating from the pulp industry, was tested for the first time as a substrate for polyhydroxyalkanoate (PHA) production by a mixed microbial culture (MMC) under aerobic dynamic feeding (ADF) conditions. A sequencing batch reactor (SBR) fed with HSSL was operated for 67. days and the selected MMC reached a maximum PHA content of 67.6%. The MMC demonstrated a differential utilization of the carbon sources present in HSSL. Acetic acid was fully consumed, while xylose and lignosulphonates were partially consumed (30% and 14%, respectively). The selected culture was characterized by Fluorescence in Situ Hybridization (FISH). Bacteria belonging to the three main classes were identified: Alpha- (72.7. ±. 4.0%), Beta- (11.1. ±. 0.37%) and Gammaproteobacteria (10.3. ±. 0.3%). Within Alphaproteobacteria, a small amount of Paracoccus (4.2. ±. 0.51%) and Defluvicoccus related to Tetrad Forming Organisms (9.0. ±. 0.28%) were detected. © 2014 Elsevier Ltd. |
