This paper describes experiments aimed at the development of a convenient method of determining the molecular weight and the molecular weight distribution of lignins and lignin-like polymers. As a model, a polymer of coniferyl alcohol prepared by enz

Several methods were investigated for increasing cellobiase activity of T. reesei cellulases produced using an acid-hydrolyzed wheat flour. The use of sorbose in cellulase production is preferred to mixed cultures with Aspergillus niger. Using 13.5 g

Soluble inducers derived from whole wheat flour were investigated for cellulase production by T. reesei . Acid-hydrolyzed wheat flour prepared using 0.3–0.6 M HCI proved to be very effective. The wheat flour hydrolyzates (13.5 g l -1 ) yielded 2.52

Waste office paper was treated with steam in a pressure vessel at 170–220°C and then enzymatically saccharified and fermented to ethanol. Steam alone was not effective in raising yields, but acid catalysed steam treatment resulted in yields of 460

A preferred process is described for efficient bioconversion of waste paper to ethanol. The paper was given a short saccharification by cellulase enzymes at 45 °C followed by fermentation in the continued presence of the enzymes at 37 °C. Ethanol y

Refuse Derived Fuels from 3 sources were converted to ethanol by enzymatic saccharification and fermentation. Two US RDFs yielded about 300 L ethanol/metric ton RDF, over 80% of theory, the others somewhat less. Potentially, RDF can make a substantia

A simple and efficient method of conversion of wheat starch B to ethanol was investigated. Employing a two-stage enzymatic saccharification process, 95% of the wheat starch was converted to fermentable sugars in 40 h. From 140 g/l total sugars in the
