Microbial degradation of polyacrylamide and the
In this work, we review the publicly available literature on the microbial degradation of polyacrylamide and its deamination product polyacrylate. To our knowledge, biotic polyacrylamide degradation has been described only very briefly in two recent reviews ( Guezennec et al., 2015 ; Joshi and Abed, 2017 ).
PAM biodegradation in high-solid anaerobic digestion for sewage sludge The time course of the acylamino content as deaminate degradation in anaerobic digestion was shown in Fig. 3 (1). 35.9% removal of the initial PAM represented by the acylamino content in the anaerobic digestion was achieved during the 26-day cultivation.
Biodegradation of Polyacrylamide and Its Derivatives
title = "Biodegradation of Polyacrylamide and Its Derivatives", abstract = "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 begins with amidase catalysed deamination of polyacrylamide to ammonia and polyacrylate. The liberated ammonia is then used as a nitrogen source for growth by the
Degradation of Polyacrylamide and Its Derivatives
General features of degradation of polyacrylamide and its anionic and cationic derivatives under the action of radical degradative agents are considered. The molecular weight of these polymers can be controlled by varying the structure and concentration of the degradative agent and salt additions, the concentration, molecular weight, and composition of the initial (co)polymer, and the process

Biomaterials for Sustained and Controlled Delivery
Cellulose and its derivatives have also been reported for their widespread acceptability in the fabrication of transdermal patches. An antiepileptic drug topiramate has been formulated in a hydroxyl propyl methyl cellulose (HPMC) based transdermal patch along with other film forming polymers.
Biodegradability certificates according to EN 13432 are difficult to achieve because the biodegradation of cellulose derivatives is a very slow process. Cellulose films (e.g., cellophane) are very transparent and exhibit an excellent barrier against oxygen and aroma if the moisture level is kept below 50% relative humidity.
- How much sewage is produced in Germany?
- More than 96 per cent of the waste water from private households or public facilities is discharged into nearby sewage treatment plants for processing. In Germany more than five billion cubic metres of sewage water are generated each year by private households, industry and trade.
- What are the different types of wastewater treatment technologies?
- The study included various wastewater treatment technologies: activated sludge, moving bed biofilm reactor (MBBR), electrocoagulation, and ozonation. Activated sludge is a well-known biological treatment technology for the removal of organic matter and can be extended to include nitrification, denitrification, and biological phosphorus removal.
- Which European country has the highest waste water reprocessing and recycling rate?
- Germany is the European country with the highest waste water reprocessing and recycling rate. More than 96 per cent of the waste water from private households or public facilities is discharged into nearby sewage treatment plants for processing.
- What methods are used in advanced wastewater treatment?
- Another method used in advanced wastewater treatment is chlorination; chlorine is among the most common methods used to disinfect wastewater effluents before discharge into streams ( Hladik et al., 2014 ), rivers ( Bellanca et al., 1977 ), or agriculture ( Ferro et al., 2015 ).
