Investigations of
preparing more highly concentrated sugar solutions using membranes
are now underway in this laboratory. Thus, the application
of membranes for concentrating sugars (using NTR-729HF, NTR-
7250, or ESNA3 membranes) and ethanol (using a perfluoropolymer
membrane) holds promise for making ethanol fermentation
from lignocellulosic materials a viable and socially beneficial
process.
