Fungal cellulolytic enzymes have been produced on soluble, purified cellulosic and lignocellulosic substrates. Strain improvement in Trichoderma reesei has increased the enzyme concentration, yield
and productivity by a factor of three.
Cái từ "by a factor of three" nghĩ là gì?.
When compared on the basis of cellulose content, lignocellulosic substrates and purified cellulosic sub-
strates gave the same amount of enzyme activity. In batch cultivation, the enzyme concentration increased with substrate concentration. Cả đoạn này nghĩa là gì ạ? và đoạn dưới nữa hihihi.
Thus, fed-batch cultivation offers the possibility of increasing the substrate concentration, and thereby the enzyme concentration, by a factor of three to four. The productivity and yield increase to
the same extent. The different substrates used in the fed-batch cultivation studies indicate that it is not only the mass transfer limitations but also the nature of the substrate that influence the enzyme production. The highest enzyme concentration was obtained with sulphite pulp.
