Study on digestibility of leaves. And the production of alcohol from leaf
.The leaves contain cellulose. Most of the waste that no time, useful. At present has an idea that will. To make changes to the leaf has more advantages, such as,,, the leaves change a pool.
.But before that. The leaves to produce a situation, sugar, will have to step through pretreatment with acid, alkali or enzyme to open the surface of the cellulose to microorganisms in. Make digest simple, such as a report of Baig et al.(2004) studied the degradation banana agro-waste in parts of the leaves and stem using the enzyme cellulase from Trichoderma lignorum was found after 24 hours have production. Reducing sugar was 1.34 mg / ml and also found that the temperature and pH soybean reducing sugar is temperature 40 ° C pH and ET and 6.0 Shah al.? (2005) were cultured Phylosticta sp. MPS-001 Aspergillus and sp.MPS-002 in food with leaves and finished as a carbon source. It was found that when cultured for 20 วนั infections, both types of enzyme activity of Cellulase Reducing sugar and highest part Jakobsson (2002) to study the optimal conditions and degradation wheat straw.Coming through to small sulfuric acid concentrated 0.2% at different temperatures, and is 190 200 210 ° C for 2 5 10 minutes, and then, to enzyme hydrolysis cellulase mix with Novozyme. A / S (Bagsvaerd Denmark), found that the temperature 200 ° C for 10 minutes, oil production, high glucose, also
Milala et al.(2005 were investigated using agricultural wastes to produce the enzyme cellulase from Aspergillus Niger by, leaf and petiole of Guinea, corn. Maize, cobsMillet rice and husks, drying and grinding finely, then, to pretreatment with sodium hydroxide concentrated 1% is time 12 hours. Fill hydrogen peroxide to final concentration of 1% for 12 hours, wash out with water, alkali refining and drying.Fermentation with Aspergillus Niger for 3 วนั found that maize cobs cellulase enzyme production value is high its e. ซึ่งสอดคล้อง with a report of Mishima et al.(2007) found that the leaves of the water and hyacinth water lettuce when being, to pretreatment with sodium hydroxide concentrated 1% will volume of water. Glucose was higher than leaf and through pretreatment Chen et al.(2007) has, corn cob to pretreatment with hydrogen sulfide concentrated 1% at 180 ° C for 3 hours. Then,. Corn cob through pretreatment to enzyme hydrolysis of cellulase from Trichoderma reesei ZU-02 and enzyme cellobiase from Aspergillus. Niger ZU-07 for 12-60.After the 60 hours corn cob was digested with enzyme, cellulase, enzyme and cellobiase can produce reducing sugar was 119.3 g / L 95.3 and g / L by Al respectively. The Caparros et al. (2008) to study the digestion sunflower stalk with high heat, the temperature in the range 160-220 ° C found that the temperature 175-185 ° C for oil contents of glucose, the highest was 0.8-1.2 g / L besides diamond and faculty (2535). The cultured Aspergillus fumigatus Fresenius 4-45-IF in food with rice straw, bagasse. Corn cob husk corn, wheat, and on to the curing temperature 40 ° C for 96 hours show ว่าเอนไซม์ cellulase from Aspergillus.Fresenius 4-45-IF can be decomposed rice straw diet. The most followed, wheat and sugarcane bagasse corn husk and corn, enzyme hydrolysis was very low. It also reported this, waste materials to produce ethanol, such as อรุณวรรณ.
