Glycolic Acid Production Using Ethylene Glycol-Oxidizing Microorganisms
Screening for microorganisms oxidizing ethylene glycol to glycolic acid was carried out. Among stock cultures, several yeasts and acetic acid bacteria showed high glycolic acid producing activity. Pichia naganishii AKU 4267 formed the highest concentration of glycolic acid, 35.3 g/l, from 10% (v/v) ethylene glycol (molar conversion yield, 26.0%). Among

THE EFFECT OF GLYCOLIC ACID AND VITAMIN C TOPICAL IN FRECKLES EFFICACY
Background: Freckles are small dark-spot hyperpigmentation on the face, upper body, and back of the hands. This hyperpigmentation develops as a result of melanocyte activity by the combination of genetic predisposition located on the basal layer and sun ...

Maleic, glycolic and acetoacetic acids-leaching for recovery of valuable metals from spent lithium-ion batteries: leaching parameters, thermodynamics and kinetics [PDF]
Environmentally friendly acid-leaching processes with three organic acids (maleic, glycolic and acetoacetic) were developed to recover valuable metals from the cathodic material of spent lithium-ion batteries (LiCoO2). The leaching efficiencies of Li and
