(some col.) ; 30 cm. + 1 computer disc Project paper (Bachelor of of Chemical engineering (Biotechnology)) -- Universiti Malaysia Pahang - 2009 Bibliography : p. 28-29 Banana stem contain 20-30 percent lignin and 60 percent cellulose. Phanerochaete chrysosporium is used to degrade the lignin to get the cellulose and hemicelluloses. Then, the cellulose and hemicelluloses will be converted to glucose by another strain. In this research, the variables studied are temperature (34oC, 40oC) and agitation rate (120 rpm, 200 rpm). The optimum temperature and agitation rate for P. chrysosporium as obtained from the literature are temperature 37oC and agitation rate 160 rpm. These set-point value were tested would gave the value of 52.9% of lignin degradation within 2 days of aerobic fermentation. A 22 factorial experiment including the variables temperature and agitation rate was designed around this optimum point. Yates’ method is used to calculate the effect of temperature, effect of agitation and the interactive effect of temperature and agitation. The result showed that the highest lignin degradation was obtained at T=37oC, 160 rpm and when the temperature and agitation were adjusted the percentage of lignin degraded is 5% only. Lignin degradation by P. chrysosporium did not favor high temperature and high agitation rate where at high temperature and agitation rate lignin degradation was very low. As conclusion, this study showed that P. chrysosporium is a very effective lignin degrader and sensitive towards changed in temperature and agitation rate.-Author- Lignin Biodegradation Biodegradable plastics Degradation 0 0 0 1 10000 10000 2019-09-04 0 TP248.27.F86 R83 2009 rs Bc. 0000043083 2019-09-04 00:00:00 1 2019-09-04 PSM 0 0 0 1 10000 10000 2019-09-04 0 CD 4073 | TP248.27.F86 R83 2009 rs Bc. 0000043084 2019-09-04 00:00:00 1 2019-09-04 PSM VIRTUA40 1689 1695 VTLSSORT0080*0200*0400*0900*1000*2450*2460*2600*3000*5020*5040*5200*6500*6501*6502*9992
