Journal ArticleDOI
Semimicro determination of cellulose in biological materials.
TL;DR: The semimicro method gives quantitative recovery of purified cellulose from microbiological culture media, and also appears to be satisfactory for cellulOSE from paper pulp.
Journal ArticleDOI
Utilization of cellulose from waste paper by Myrothecium verrucaria
TL;DR: In this paper, the maximum protein synthesis rate and the maximum final protein concentration were achieved by growing Myrothecium verrucaria from ball-milled newspaper in aerated stirred-jar fermentors.
Journal ArticleDOI
Kinetics of diffusion-coupled fermentation processes: The conversion of cellulose to protein
L. W. Ross,David M. Updegraff +1 more
TL;DR: A combination of Fickian diffusion and Michaelis–Menten kinetics is proposed to describe the rate of diffusion‐coupled biochemical reactions, which leads to a nonlinear mathematical model which is solved by a perturbation technique.
Journal ArticleDOI
A rapid micro gas analysis system for carbon dioxide, oxygen, hydrocarbon gases, and hydrogen.
TL;DR: The percentage of carbon dioxide, oxygen, hydrocarbon gases, hydrogen, and inert gases may be determined in a sample of 50 to 100 μl with a precision of ±0.5% with the use of an apparatus applicable to multicomponent systems.
