Production of bacterial cellulose from waste fiber sludge
摘要
Abstract
Bacterial cellulose (BC)is a nanostructured polymer product of some bacteria,principally acetic acid bacteria. Compared to plant cellulose,BC has a great potential in wide applications due to its unique properties. Because of the high cost of culture medium,large-scale industrial production and commercial application of BC were limited. In this work,two different waste fiber sludges,sulfate fiber sludge (SAFS)and sulfite fiber sludge (SIFS)were easily hydro-lyzed by cellulase without prior thermochemical pretreatment and thereafter were used to produce BC successfully. The yield and structure of BC produced from the two different fiber sludges were compared. The results indicated that the yield of BC from SAFS were 9. 0 g/L,which was about 17% higher than that of SIFS (7. 7 g/L). The crystallinity of the BC membranes differed due to the culture media. The crystallinity of BC from SAFS hydrolysate was around 61%,while that from SIFS hydrolysate was around 66%,both of them were lower than that (78%)from the glucose-based reference medi-um. ATR-FTIR analysis showed that there were no significant differences in the chemical compositions of BC membranes obtained from the two waste fiber sludges and glucose-based media.关键词
