Mulching is used to improve the condition of agricultural soils by covering the soil with different materials, mainly black polyethylene (PE). However, problems derived from its use are how to remove it from the field and, in the case of it remaining in the soil, the possible effects on it. One possible solution is to use biodegradable plastic (BD) or paper (PP), as mulch, which could present a...

Paraphoma sp. B47-9 is a producer of a biodegradable plastic-degrading enzyme. Here, we report the draft genome sequence of this strain. The draft genome assembly has a size of 39.3 Mb with a GC content of 52.4% and consists of 185 scaffolds.

The progressive application of new biodegradable plastics in agriculture calls for improved testing approaches to assure their environmental safety. Full biodegradation (≥90%) prevents accumulation in soil, which is the first tier of testing. The application of specific ecotoxicity tests is the second tier of testing needed to show safety for the soil ecosystem. Soil microbial nitrification is ...

this paper discusses about preparation of biodegradable polymer /clay nanocomposites based on organically modified montmorillonite clay; i.e. cloisite 10a and biodegradable polymer chitosan by solution mixing technique and their characterization. the nanocomposites were successfully prepared and their structures were characterized by powder x-ray diffraction (xrd), particle size analyzer (beckm...

magnesium alloys as biodegradable materials can be used in body as an implant materials but since they have poor corrosion resistance, it is required to decrease their corrosion rate by biocompatible coatings. in this study, hydroxyapatite (ha) coatings in the presence of an intermediate layer of zrn as a biocompatible material, deposited on az91 magnesium alloy by ion beam sputtering method at...

A practical antibiotics-free plasmid expression system in cyanobacteria was developed by using the complementation of cyanobacterial recA null mutation with the EscherichiacolirecA gene on the plasmid. This system was applied to the production of polyhydroxyalkanoate (PHA), a biodegradable plastic, and the transgenic cyanobacteria stably maintained the pha genes for PHA production in the antibi...

A new generation of partially or even fully biodegradable implants is emerging. The idea of using temporary devices is to avoid a second surgery to remove the implant after its period of use, thereby improving considerably the patient's comfort and safety. This paper provides a state-of-the-art overview and an experimental section that describes the key technological challenges for making biode...
