    An evaluation of a ceramic monolith as an enzyme support material (1975)
    New York, NY [u.a.] : Wiley-Blackwell
    Biotechnology and Bioengineering 17 (1975), S. 1617-1626

    Notes: Catalase was immobilized on commercially available monolithic catalyst supports and also on participate support obtained by crushing the monolith. The kinetics of the monolith- and particulate-supported enzymes were analyzed in a continuous tubular reactor system and pressure drop was also monitored. Analysis of the results indicates that the monolith-supported system presents very little resistance to flow which results in a considerably smaller pressure drop than is obtained in flow through particulate-supported systems under comparable conversion conditions. Ceramic monoliths thus appear to be very suitable for use as enzyme supports in continuous tubular reactor applications, particularly where high pressure drops might be expected.

    Notes: Effects of time, temperature, and pH during the steam explosion of poplar wood were studied with the aim of optimize both pentoses recovery and enzymatic hydrolysis efficiency. Steam explosion of acid impregnated wood chips allowed the recovery of 70% of potential xylose as monomers (217°C, 120 s) Enzymatic hydrolysis of pretreated fiber with Trichoderma reesei CL-847 cellulase system increased progressively with the severity of the steam treatment conditions. The best yield in term of glucose recovery after 24 h of enzymatic hydrolysis was 70% of potential glucose (225°C, 120 s). Deactivation by adsorption on lignin of Trichoderma reesei cellulases and inhibition of these enzymes by low-molecular-weight phenols and trihydroxybutyric acids were noticed.
