The combined EGSB-ABR biosystem consisted of an EGSB reactor followed by an ABR ().The EGSB reactor was applied as the pretreatment of ABR. The EGSB reactor was made of plexiglass with 20 cm internal diameter and 210 cm height providing a working volume of 65 L, and a gas-liquid-solids separator was installed at the top of the column to separate the solids and biogas from the liquid phase.

biodegradation of polyacrylamide and its derivatives

Biodegradation of Polyacrylamide and Its Derivatives

Although polyacrylamide (PAM) and its derivatives have many useful applications, their release in nature can have impacts on the environment and human health, thus bioremediation approaches for residual PAM are urgently needed. Biodegradation of PAM and its derivatives has been studied only in the last two decades, with most emphasis on acrylamide biodegradation.

Biodegradation of polyacrylamide by anaerobic digestion

Polyacrylamide (PAM) used in sludge dewatering widely exists in high-solid anaerobic digestion. Degradation of polyacrylamide accompanied with accumulation of its toxic monomer is important to disposition of biogas residues. The potential of anaerobic digestion activity in microbial utilization of PAM was investigated in this study.

Fuel oxygenates such as methyl and ethyl tert- butyl ether (MTBE and ETBE, respectively) are degraded only by a limited number of bacterial strains. The aerobic pathway is generally thought to run via tert- butyl alcohol (TBA) and 2-hydroxyisobutyrate (2-HIBA), whereas further steps are unclear. We have now demonstrated for the newly isolated β-proteobacterial strains L108 and L10, as well as

Camembert cheese is a surface white mould ripened cheese; when full ripe the casein becomes liquefy as the intensive degradation occurs by proteinases from surface flora and results over-ripening and off flavor. To control this, partial purified bacteriocin like substances (PPBLS) from newly lactic acid bacterial isolate (LAB100) exhibited antifungal activity against <i>Penicillium candidum</i
