Isolation and Characterization of Polyacrylamide-Degrading
The microbial biodegradation of PAM has long been studied. Previous studies suggested that microorganisms are able to degraded and utilized PAM as a nitrogen source in both aerobic and anaerobic environments [13,14]. Microorganisms produce a polyacrylamide induced amidase to deaminate PAM .

Isolation and Characterization of Polyacrylamide-Degrading
Polyacrylamide (PAM) is a water-soluble polymer that is widely used as a flocculant in sewage treatment. The accumulation of PAM affects the formation of dewatered sludge and potentially produces hazardous monomers. In the present study, the bacterial strain HI47 was isolated from dewatered sludge. This strain could metabolize PAM as its sole nutrient source and was subsequently identified as
Plastic waste is an issue of global concern because of the environmental impact of its accumulation in waste management systems and ecosystems. Biodegradability was proposed as a solution to overcome this problem; however, most biodegradable plastics were designed to degrade under aerobic conditions, ideally fulfilled in a composting plant. These new plastics could arrive to anaerobic
- What are the different colors of polyaluminium chloride?
- The color variations in Polyaluminium Chloride (PAC) signify differences in raw materials, production processes, and applications. White PAC and Light Yellow PAC are ideal for applications demanding high purity, such as drinking water treatment, while Yellow PAC and Brown PAC provide cost-effective solutions for various water treatment scenarios.
- What is high-purity poly-aluminum chloride (PACL)?
- Poly-aluminum chloride (PACl) is one of the common coagulants for water and wastewater treatment. A new Chinese national standard of PACl has been implemented, where the concentration of insoluble substances, iron and heavy metals is to be controlled strictly, then researches on the preparation of high-purity PACl are needed.
