Maintenance of chondrocyte phenotype during expansion on PLLA microtopographies
Articular chondrocytes are difficult to grow, as they lose their characteristic phenotype following expansion on standard tissue culture plates. Here, we show that culturing them on surfaces of poly(L-lactic acid) of well-defined microtopography allows ...

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