Selectively enriched mixed sulfate-reducing bacteria for acrylamide biodegradation
Acrylamide (AM) is a carcinogen and neurotoxicant, and its growing application in numerous industrial processes is contaminating the environment. In addition, the inhibitory effect of AM makes its biodegradation in the environment challenging.

The aim of this review was to summarize information and scientific data from the literature dedicated to the fate of polyacrylamide (PAM)-based flocculants in hydrosystems. Flocculants, usually composed of PAMs, are widely used in several
Effect of Natural Rubber Contents on Biodegradation and Water Absorption of Interpenetrating Polymer Network (IPN) Hydrogel from Natural Rubber
2.8 Biodegradation in soil test The examination of biodegradation of IPN NR/St was applied from Ref. [3]. The specimen (2 cm x 2 cm) was buried under soil at 7 cm from top soil (Ubon Ratchathani, Thailand). The water was poured into the samples
Materials The AA and AM monomers were purchased from Thai Mitsui Specialty Chemicals (Thailand). Potassium hydroxide (KOH), ammonium persulfate (APS) and hydrogen peroxide (commercial grade) were purchased from Ajax (Australia). N,
Isolation and Characterization of Polyacrylamide-Degrading Bacteria from Dewatered Sludge - ResearchGate
Changes in the molecular weight and viscosity of HPAM with microorganisms enriched from activated sludge have also been reported in recent studies (e.g., Dai et al. 2014;Yu et al. 2015;Sang et al
Therefore, new advances want to go further in the biodegradation. of PLA, the simulated system based on aerobic biodegradation of. PLA may be established in the near future. 2. Synthesis

Examples of microorganisms that have been shown to degrade acrylamide are Rhodococcus sps. [20], Pseudomonas aeruginosa BAC-6 isolated from industrial effluent [6], free and immobilized cells of
Synthesis and quantitative analyses of acrylamide-grafted poly(lactide-co-glycidyl methacrylate) amphiphilic copolymers for environmental
In medical applications, non-biodegradable polymeric materials also have many drawbacks. For instance, a non-biodegradable implant requires a second surgical procedure for removal, and likewise, drug delivery using non-biodegradable polymers
Preparation of Polyacrylamide Grafted onto Magnetic Cellulose as Flocculant in Wastewater Pre-treatment Application the natural polymer is vulnerable to biodegradation as the 01 Proceedings of the International Conference on Industrial
- Why is flocculation important in industrial wastewater treatment?
- Flocculation is an essential phenomenon in industrial wastewater treatment. Inorganic coagulants (salts of multivalent metals) are being commonly used due to its low cost and ease of use. However, their application is constrained with low flocculating efficiency and the presence of residue metal concentration in the treated water.
- How do flocculants affect water treatment efficiency?
- As the core of flocculation, flocculants’ characteristics directly determine the efficiency of water treatment (Liao et al. 2014). According to the chemical composition, the flocculant can be divided into inorganic coagulants and organic flocculants.
- How much flocculant can be used in wastewater treatment plants?
- Research by Vu Hien Phuong To et al. on sludge from seven different wastewater treatment plants show that the dose of flocculant is strongly dependent on the concentration of SEPS. Up to 80% of the PAM used can be used up in reaction with the SEPS.
- Is flocculant a good water treatment method?
- Therefore, it can be called a very economical and effective water treatment method. Flocculant is a kind of water treatment agent. It can aggregate the colloidal substances and particulate matters suspended in the liquid to form larger flocs, and then promote the settlement of these particles from the stable suspension (Salehizadeh et al. 2018).
