Robust poly(lactic acid) membranes improved by polysulfone-g-poly(lactic acid) copolymers for hemodialysis

open access: yes, 2015
Poly(lactic acid) (PLA) is a sustainable membrane candidate for liquid separation and purification. However, the inherent brittleness restrains its practical application, especially for a porous membrane with thin thickness and high porosity.

In silico simulation of lactic acid production in a continuous stirred tank bioreactor

open access: yes, 2023
reservedL'acido lattico è una molecola idrossicarbossilica con ampie applicazioni industriali. Il suo principale processo di sintesi prevede la fermentazione tramite batteri lattici, che consentono la produzione di enantiomeri specifici anziché una ...

Preparation, Foaming and Characterization of Poly(l-lactic acid))/Poly(d-lactic acid)-Grafted Graphite Oxide Blends

open access: yes, 2018
Commercial poly(l-lactic acid) (PLLA) was blended with different contents of graphene oxide-graft-poly(d-lactic acid) (GO-g-PDLA), which was synthesized via ring-opening polymerization using modified GO as initiator.

Application of a pH Feedback-Controlled Substrate Feeding Method in Lactic Acid Production

open access: yes, 2010
Substrate concentration in lactic acid fermentation broth could not be controlled well by traditional feeding methods, including constant, intermittent, and exponential feeding methods, in fed-batch experiments.

Online monitoring of lactic acid fermentation by means of Proton-Transfer-Reaction Mass Spectrometry

open access: yes, 2014
Proton-Transfer-Reaction Time-of-Flight Mass Spectrometry (PTR-ToF-MS) is an analytical technique based upon the “soft”ionization of a gaseous matrix, followed by mass spectrometric separation, performed at high time and mass resolution.
