Microbial production of D-lactic acid from dried distillers grains with solubles [PDF]

open access: yes, 2019
D-Lactic acid production is gaining increasing attention due to the thermostable properties of its polymer, poly-D-lactic acid (PDLA). In this study, Lactobacillus coryniformis subsp. torquens, was evaluated for its ability to produce D-lactic acid using

Miscibility Evaluation of Poly(L-Lactic Acid)/Poly(Lactic Acid-co-lysine) Blends [PDF]

open access: yesJournal of Applied Biomaterials & Functional Materials, 2016
Background The amorphous poly(lactic acid- co-lysine) (PLL) with hydrophilic reactive groups was synthesized by the condensing copolymerization and the blending miscibility of poly(L-lactic acid) (PLLA) and PLL was investigated. Methods The miscibility of PLLA and PLL was evaluated by analyzing the thermal properties, crystallization behaviors, crystal

How to combine a hydrophobic matrix and a hydrophilic filler without adding a compatibilizer – Co-grinding enhances use properties of renewable PLA-starch composites [PDF]

open access: yes, 2012
In order to avoid the use of compatibilizers or plasticizers, co-grinding was performed to produce PLA – starch composite materials. Fragmentation and agglomeration phenomena were analysed to propose a production mechanism.
