Operating Conditions for High Production Rates of Ethanol in a Continuous Two-Stage Fermenter with Cell Recycle

Autor: Akio Nishiwaki, I. J. Dunn

Publikováno v: The Canadian Journal of Chemical Engineering. 83:904-908

A continuous two-stage fermenter with cell recycle at each stage is studied numerically for efficient production of ethanol. In this system, both filtrate and bleed from the first stage are provided to the second fermenter. Using a product-inhibition

Effect of longitudinal mixing on microbial growth in a multi-stage column bioreactor

Autor: I. J. Dunn, A. Nishiwaki, J. R. Bourne

Publikováno v: Journal of Chemical Technology & Biotechnology. 48:227-237

The performance of a multi-stage column bioreactor for nonlimited microbial growth was studied. The back-flow model was employed to describe the flow pattern of the microbial suspension. Analytical solutions for calculating the microbial cell concent

Analysis of fed-batch fermentation processes by graphical methods

Autor: I. J. Dunn, Suteaki Shioya

Publikováno v: Journal of Chemical Technology and Biotechnology. 29:180-192

Graphical methods are used for many types of engineering calculations. Their appeal is often related to calculational simplicity, but probably the increased understanding that accompanies a graphical calculation method is chiefly responsible for thei

Comparison of Lactic Acid Productivities at High Substrate Conversions in a Continuous Two-stage Fermenter With Cell Recycle Using Different Kinetic Models

Autor: A. Nishiwaki, I. J. Dunn

Publikováno v: Chemical Engineering Communications. 192:219-236

The steady-state performance of a two-stage recycle fermenter with two different types (I and II) of configurations for staging was investigated numerically for the continuous production of lactic acid. In Type I the bleed broth withdrawn from the fi

Analysis of acetic acid productivity in a continuous two-stage bioreactor with cell recycling

Autor: I. J. Dunn, Akio Nishiwaki

Publikováno v: Journal of Chemical Technology & Biotechnology. 80:371-375

The performance of a two-stage system with cell recycling and fresh feed at each stage is studied numerically for continuous acetic acid production. In this system, both filtrate and bleed broth from the first stage are supplied to the second ferment

Water treatment using sequenced ozonation and SBR biofilm reactors

Autor: Massimo Morbidelli, I. J. Dunn, D. Carini

Publikováno v: Journal of Chemical Technology & Biotechnology. 78:1157-1165

The degradation of 3-methylpyridine (3MEP), a model heterocyclic industrial molecule, was performed in a sequential batch ozonation–biofilm process. Four process steps (bubble-column ozonation, heterotrophic biofilm degradation, biofilm nitrificati

Autor: U. von Gunten, Massimo Morbidelli, I. J. Dunn, D. Carini

Publikováno v: Ozone: Science & Engineering. 23:359-368

A combined chemical-biological treatment of industrial wastewater using ozonation as the first step of a Sequencing Batch Biofilm Reactor (SBBR) process, in which 3-methylpyridine (3MEP) was degraded as a model industrial pollutant, has been develope

Transient-state behavior of a biofilter removing mixtures of vapors of MEK and MIBK from air

Autor: Marc A. Deshusses, I. J. Dunn, Geoffrey Hamer

Publikováno v: Biotechnology and Bioengineering. 49:587-598

In the work reported here, selected aspects of the dynamic behavior of biofilters for waste air treatment have been investigated. Emphasis was placed on transient state elimination of mixtures of methyl ethyl ketone (MEK) and methyl isobutyl ketone (
