Control of interspecies electron transfer flow during anaerobic digestion: Dynamic diffusion reaction models for hydrogen gas transfer in microbial flocs
(Wiley Subscription Services, Inc., A Wiley Company, 1989-02-05)
Dynamic reaction diffusion models were used to analyze the consequences of aggregation for syntrophic reactions in methanogenic ecosystems. Flocs from a whey digestor were used to measure all model parameters under the ...
A new isolation and purification method for staphylococcal protein A using membrane encapsulated rabbit IgG-agarose
(Wiley Subscription Services, Inc., A Wiley Company, 1989-10-20)
A new isolation and purification method for bioproducts using membrane-encapsulated affinity adsorbents was investigated. The new method involves encapsulation of affinity adsorbents, batch adsorption of the bioproduct ...
Equivalence between S-systems and Volterra systems
(Elsevier, 1986-03)
S-systems and Volterra systems have been developed independently of each other in different branches of biology. We show that these systems are mathematically equivalent.
The consequences of earlier reproduction in declining populations
(Elsevier, 1984-10)
Conflicting claims have been published concerning the consequences of earlier reproduction. In particular, it has been claimed that earlier reproduction will increase the rate of decline in a declining population, have no ...
The age structure of populations of Saccharomyces cerevisiae
(Elsevier, 1981-04)
A discrete deterministic model is described for the growth of an age-structured population of yeast, Saccharomyces cerevisiae, incorporating recent information on the asymmetry of cell division and control of the cell cycle ...
Protein release from Escherichia coli cells permeabilized with guanidine–HCl and Triton X100
(Wiley Subscription Services, Inc., A Wiley Company, 1989-02-20)
An important factor complicating the recovery of recombinant proteins from Escherichia coli is their intracellular location. An alternative to the commonly used method of releasing these proteins by mechanical disruption ...
Substrate-dependent differences in production of extracellular matrix molecules by squamous carcinoma cells and diploid fibroblasts
(Wiley Subscription Services, Inc., A Wiley Company, 1989-04-20)
Two human squamous carcinoma cell lines and human diploid fibroblasts were examined for the production of extracellular matrix (ECM) molecules including fibronectin (FN), laminin (LN), and thrombospondin (TSP) when grown ...
Effects of phosphate, glucose, and ammonium on cell growth and lincomycin production by Streptomyces lincolnensis in chemically defined media
(Wiley Subscription Services, Inc., A Wiley Company, 1985-03)
Cell growth and lincomycin production were measured in batch cultures of Streptomyces lincolnensis in chemically defined media. In these fermentations the specific rate of antibiotic production was maximal during growth ...
Growth of three established cell lines on glass microcarriers
(Wiley Subscription Services, Inc., A Wiley Company, 1983-05)
Three established cell lines were examined for growth on a newly developed microcarrier which consists of glass beads. The cells were simultaneously exmined for growth on commercially available microcarriers made from ...
Interaction of infectious viral particles with a quaternary ammonium chlorid (QAC) surface
(Wiley Subscription Services, Inc., A Wiley Company, 1989-08-20)
The antiviral activity of a surface-bonded quaternary ammonium chloride (QAC) was examined in this study. The mechanism of inactivation was elucidated by a combination of infectivity assay, radioactive labeling assay, and ...
