Polyamide-6 (also known as nylon-6) is one of the biodegradable-resistant synthetic polymers used in the manufacturing of commodity plastic materials. The environmental effects of the persistence of this material in landfill pose a global problem of disposal system. Knowledge of the microbial pattern of interaction with this plastic will provide the biological resources and scientific basis for the development of sustainable disposal and treatment method. Anoxybacillus rupiensis Ir3 (JQ912241) is a novel thermophilic bacterium, it was isolated from hydrocarbon contaminated soil in Iraq and showed good ability to utilize aromatic compounds, It is represented a new carbazole-degrading bacterium. In an attempt to investigate the ability of this bacterium to degrade nylon6, the strain Ir3 was grown on the nylon6 separately as a sole source of carbon and nitrogen. Results showed that strain Ir3 was able to degrade this compound. Optimum conditions for degradation of nylon6 were investigated. It was found that these conditions are growing this bacterium in chemical define media CDM containing (0.5%) nylon6, and incubated with shaking (180rpm) at 65°C for 7 days, and to confirm the ability to degrade nylon6, analytical experiments HPLC (High Performance Liquid Chromatography) and FTIR (Fourier Transmittance Infrared Spectroscopy) were used. The 6-aminohexanoic acid as intermediate products in the culture medium was mentioned by using HPLC, while biodegradation of the nylon6 was monitored by using FTIR.

“…PBA is four‐carbon polyamide synthesized from 2‐pyrrolidone, which can be made by means of decarboxylation of glutamate . The main advantage of this polymer stems from its good hydrophilic nature while mechanical properties such as modulus and elongation at break (Eb) are comparable to those of nylon 6 . But the application of PBA in tissue engineering and medicine generation has never been studied.…”

In this study, polybutyrolactam (PBA) was synthesized, and the PBA/chitosan (CS) blended films were fabricated for wound dressings. The results showed that the surface roughness of the blended films decreased with the increasing ratios of CS. In addition, the tensile strength of the film with 50 wt % CS (NC50) was about 33.6 MPa and the highest compared with other films. The hydrophilicity of the blended films gradually decreased while the water vapor transmission rates (WVTRs) increased with the increase of CS content. Moreover, the blended films could be biodegradable in phosphate buffer saline. Both PBA and blended films were non‐toxic and good for L929 cells growth, showing good cytocompatibility. Furthermore, the NC50 was found to promote the cell proliferation better than other groups. It can be suggested that the NC50 combined the advantages of both PBA and CS well. Therefore, the NC50 with good cytocompatibility, mechanical properties, and WVTRs might be suitable for wound dressing applications. © 2018 Wiley Periodicals, Inc. J. Appl. Polym.

“…Poly(2‐pyrrolidone) (Polyamide 4, Nylon 4) is prepared by the polymerization of 2‐pyrrolidone (PD), a five‐membered ring lactam, which can be synthetized also from biomass using Escherichia coli by way: glucose, L‐glutamic acid, γ‐aminobutyric acid, and 2‐pyrrolidone . Polyamide 4 (PA4) is also a biodegradable polymer that decomposes in the compost soil and activated sludge …”

A successful preparation of polyamide 4 nanofibers via electrostatic spinning with diameters close to 100 nm is described. Polyamide 4 was prepared by the anionic ring‐opening polymerization of 2‐pyrrolidone and characterized. The effect of the system parameters (i.e., molar mass of the polymer, the solvent system) and the process parameters (i.e., the electrode‐to‐collector distance) during the electrostatic spinning have been studied. The morphology of the polyamide 4 fiber layers is given except molar mass of the polymer and the concentration of its solution primarily by the conformation of polyamide chains due to polyelectrolyte effect which was confirmed by viscosity measurements. © 2017 Wiley Periodicals, Inc.
