The concentration of polymerised sugars in enzymic hydrolysates from lignocellulosic materials was determined by high pressure liquid chromatography (h.p.l.c.) of hydrolysates before and after dilute acid hydrolysis: significant quantities of polymer

A method for the simulation of a 3-stage counter-current plug-flow reactor (PFR) for the enzymic Saccharification of alkali-treated (a.t.) sugar cane bagasse is described. The PFR gave higher conversion than a conventional stirred-tank reactor (STR).

Acid and alkali pretreatments were studied to identify those factors which are critical in determining the susceptibility of a lignocellulosic substrate (bagasse) to enzymic hydrolysis. The different effects of each treatment on the structure of the

The dinitrosalicylic acid (DNS) method gives a rapid and simple estimation of the extent of saccharification by measuring the total amount of reducing sugars in the hydrolysate. However, it is subject to interference by citrate buffer and other subst

The alkali pretreatment of sugar cane bagasse was optimised and compared with an optimised steam (acid) pretreatment. The optimised alkali pretreatment gave an overall sugar yield of 37.4 g sugars per 100 g bagasse accounting for 43.8% of the initial

Evidence is presented which supports the view that two routes exist for the formation of glucose when cellulosic material is saccharified using T. reesei enzyme preparations. The first is via cellobiose and for the second, glucose appears to be forme

The aim of this review is to examine the literature relevent to the hydrolysis of cellulose in lignocellulosic materials. It is a complex process involving the nature of the cellulose itself and its association with other substances such as lignin an

The action of cellulase [see 1,4-(1,3;1,4)-β- d -glucan 4-glucanohydrolase, EC 3.2.1.4] preparations from Trichoderma reesei QM9414 and C30 has been compared on Sigmacell, Solka Floc and alkali-treated bagasse in the presence and absence of added d
