Polylactic acid (PLA)
This website provides an excellent overview of PLA as a polymer, its properties, and manufacture. This web article describes the production of lactic acid from biomass by microbial fermentation coupled to a poly-merization process to make PLA. The article is a bit dated and its industrial projections are now seen to be a bit over-optimistic. NatureWorks is the company that started large-scale p...
متن کاملFilms of Poly (L - Lactic Acid) / Poly(Hydroxybutyrate-Co-Hydroxyvalerate) Blends: In vitro Degradation
Biocompatible and biodegradable polymers have been studied in the last few years with good clinical success in the fixation and stabilization of bone fractures. The understanding and the control of the polymeric prosthetic degradation process and the effect of its degradation products in the organism are crucial for the success of the implant. In this present work, blends of PLLA/PHBV, obtained...
متن کاملMicrobial degradation of poly(3-hydroxybutyrate) and poly(3-hydroxybutyrate-co-3-hydroxyvalerate) in soils.
The microbial degradation of tensile test pieces made of poly(3-hydroxybutyrate) [P(3HB)] or a copolymer of 90% 3-hydroxybutyric acid and 10% 3-hydroxyvaleric acid was studied in soils incubated at a constant temperature of 15, 28, or 40 degrees C for up to 200 days. In addition, hydrolytic degradation in sterile buffer at temperatures ranging from 4 to 55 degrees C was monitored for 98 days. D...
متن کاملProduction and characterization of biodegradable terpolymer poly(3-hydroxybutyrate-co-3-hydroxyvalerate-co-4-hydroxybutyrate) by Alcaligenes sp. A-04.
The production of the terpolymer poly(3-hydroxybutyrate-co-3-hydroxyvalerate-co-4-hydroxybutyrate), P(3HB-co-3HV-co-4HB), by Alcaligenes sp. A-04 was investigated to determine the superior biodegradable polymer properties over those of poly(3-hydroxybutyrate), P(3HB), and its copolymers. The highest terpolymer content of 68% (w/w) was produced by Alcaligenes sp. A-04 at 60 h by shake-flask cult...
متن کاملThe Degradation of Polylactic Acid Aiber
Polylactic acid (PLA) fiber, also known as corn fiber, is made of corn and other grains through fermentation, polymerization and spinning. Thus it is biodegradable and environmentally friendly. Three kinds of buffer solutions with PH values of 4, 7.2 and 11 were made for the investigation of the degradation properties of PLA. The experimental results showed that the degradation of polylactic ac...
