Evaluation of the potential of a bead mill for the release of intracellular bacterial enzymes

Publikováno v: Enzyme and Microbial Technology. 4:385-389

The suitability of bead mills for the release of intracellular bacterial enzymes has been studied using the Dyno-Mill Model KDL. The effect of cell concentration, bead size and agitation speed on the release of beta-lactamase from Enterobacter cloaca

Tangential flow filtration ? A new method for the separation of bacterial enzymes from cell debris

Autor: Alan V. Quirk, John R. Woodrow

Publikováno v: Biotechnology Letters. 5:277-282

The ability of tangential flow filtration to separate enzymes from cell debris in bacterial homogenates has been studied. Homogenates of two organisms which are difficult to clarify by centrifugation were tested. Ultrafiitration membranes gave very l

Anomalous partitioning of aryl acylamidase in aqueous two-phase systems

Autor: Alan V. Quirk, John R. Woodrow

Publikováno v: Enzyme and Microbial Technology. 8:183-187

The use of aqueous two-phase systems for the extraction of aryl acylamidase (aryl-acylamide amidohydrolase, EC 3.5.1.13) from cell lysates of Pseudomonas fluorescens has been examined in an attempt to improve the large scale purification of this enzy

Investigation of the parameters affecting the separation of bacterial enzymes from cell debris by tangential flow filtration

Autor: John R. Woodrow, Alan V. Quirk

Publikováno v: Enzyme and Microbial Technology. 6:201-206

The effect of organism, enzyme, method of cell breakage and membrane characteristics on the separation of bacterial enzymes from cell debris by tangential flow filtration has been studied. The effectiveness of separation was assessed by process time,

The use of derivative spectrophotometry for the rapid measurement of substrate and product concentration in fermentation

Autor: John R. Woodrow, Kathleen Spear

Publikováno v: Applied Microbiology and Biotechnology. 19:177-180

Derivative spectrophotometry has been used to study the culture of Pseudomonas fluorescens NCIB 11615 grown in complex medium containing acetanilide. By using fourth derivative spectra it has proved possible to determine both acetanilide (substrate)

Isolation and preliminary taxonomic studies of Thermus strains isolated from Yellowstone National Park, USA

Autor: John R. Woodrow, Michael J. Munster, Richard J. Sharp, Ann P. Munster

Publikováno v: Journal of general microbiology. 132(6)

Summary: Forty-eight strains of Thermus isolated from hot springs in Yellowstone National Park, Wyomming, USA, and eight reference strains were subjected to a numerical taxonomic analysis using Gower's coefficient (SG ) with single and average linkag
