Notizen:
X s), enzyme/substrate (E/S) ratios (X e) and incubation time (X t) on the preparation of palmitoyl lactic acid using Mucor miehei lipase (MML) and porcine pancreas lipase (PPL). Experimental ester yields were found to be in good agreement with predictions. In the case of MML, the ester yield was found to increase with X e and X t and a maximum yield of 27 mM was obtained at X e=128 activity units(AU)/mM of substrate, X s=64–74 mM and X t=72 h. In the case of PPL, the ester yield was found to increase with increases in X e and X s. Optimum conditions for PPL were X e=45 AU/mM, X s=85–90 mM and X t=72 h, at which the maximum ester yield of 15 mM was obtained.
