Microcrystalline cellulose was activated with diphenylmethane 4,4-diisocyanate and triethylamine and was used to immobilize beta-galactosidase (beta-Gal) at 4 or 20C and pH 3.6 or 4.6. The activation procedure modified the electrokinetic characteristics of the carrier, making the zeta potential less negative; at pH below 4.5 the zeta potential became positive. Immobilization of beta-Gal shifted the isoelectric point to acid pH. Conditions to produce the highest residual beta-Gal activity were pH 4.6 and temp. of 4C. Addition of 1250 p.p.m. NaCl, CaCl2 or Ca(NO3)2 at the optimum pH decreased beta-Gal activity, effects being greater for the immobilized enzyme than for free enzyme. Optimum pH after immobilization was increased by approx. one unit by Ca salts, while Na had no effect. Ca(NO3)2 caused a shift of zeta potential to more positive values and the isoelectric point of the immobilized enzyme to alkaline pH. Na had less influence on zeta potential but at 50 p.p.m. did displace the isoelectric point. [less ▲]

Chemical and enzymatic hydrolysis of cellulose are compared. Basic research on paper mill celluloses shows that it is mainly the endo- and exocellulase activities which are absorbed on the substrate. In the case of the Trichoderma reesei complex with Aspergillus niger beta-glucosidase, the exocellulase activity has proved to be the limiting factor in the design of a reactor which recycles the enzyme complex. Tests were carried out on various pretreatments for substrates of more complex chemical composition, such as straw, maize stalks, beet pulp. The rate and overall degree of hydrolysis, especially for straw, were improved by chemical treatments in combination with mechanical processes. A first pilot plant for straw hydrolysis was set up with the aim of attaining high sugar concn in the fermenter. [less ▲]
