A new approach to recycle oxalic acid during lignocellulose pretreatment for xylose production

open access: yesBiotechnology for Biofuels, 2018
Background Dilute oxalic acid pretreatment has drawn much attention because it could selectively hydrolyse the hemicellulose fraction during lignocellulose pretreatment. However, there are few studies focusing on the recovery of oxalic acid.

Pre-transplant residual diuresis and oxalic acid concentration influence kidney graft survival. [PDF]

open access: yesPLoS ONE
Background and hypothesisOxalic acid, a toxic metabolic end product, accumulates when kidney function deteriorates. Apart from its direct tubulotoxicity, it crystallizes at concentrations above 30-40 µmol/L.
