Here, we present a first report of the evaluation of the activity,
specificity and regioselectivity of different lipases [lipases
from Pseudomonas fluorescens (PFL), Candida rugosa (CRL),
Thermomyces lanuginosa (TLL), Rhizomucor miehei (RML),
Candida antarctica fraction B (CAL-B) and fraction A (CALA),
Aspergillus niger (ANL) and Aspergillus oryzae (AOL)]
[16–23] in the hydrolysis of peracetylated -d-galactose (1) and
peracetylated N-acetyl--d-glucosamine (2).
