λ Vectors for Stable Cloned Gene Expression
Biotechnology Progress - Tập 6 Số 4 - Trang 277-282 - 1990
Nandan Padukone, S. Peretti, David F. Ollis
AbstractThe bacteriophage λ offers a unique opportunity concurrently to minimize segregational instability in recombinant systems by chromosomal integration of the cloned gene and to achieve high cloned gene expression during an abortive lytic phase. Lysis leads approximately to a 100‐fold amplification of the cloned gene. Cell lysis in the lytic state is blocked b...... hiện toàn bộ
Electrophysiological Model of Intact and Processed Plant Tissues: Cell Disintegration Criteria
Biotechnology Progress - Tập 15 Số 4 - Trang 753-762 - 1999

Process Design and Costing of Bioethanol Technology: A Tool for Determining the Status and Direction of Research and Development
Biotechnology Progress - Tập 15 Số 5 - Trang 794-803 - 1999
Robert Wooley, Mark Ruth, David A. Glassner, John Sheehan
AbstractBioethanol is a fuel‐grade ethanol made from trees, grasses, and waste materials. It represents a sustainable substitute for gasoline in today's passenger cars. Modeling and design of processes for making bioethanol are critical tools used in the U.S. Department of Energy's bioethanol research and development program. We use such analysis to guide new direc...... hiện toàn bộ

Clavulanic Acid Degradation in Streptomyces clavuligerus Fed‐Batch Cultivations
Biotechnology Progress - Tập 18 Số 3 - Trang 451-457 - 2002
Johannes A. Roubos, Preben Krabben, W. T. A. M. De Laat, Robert Babuška, Joseph J. Heijnen
AbstractClavulanic acid (CA) is an important antibiotic that is produced by Streptomyces clavuligerus. CA is unstable and product degradation has turned out to have a major impact on product titers in fed‐batch cultivations. Three different types of experiments have been used to elucidate CA degradation under fed‐batch cultivation conditi...... hiện toàn bộ
Unusual Thermal Stability of Soybean Peroxidase
Biotechnology Progress - Tập 12 Số 4 - Trang 555-558 - 1996
James P. McEldoon, Jonathan S. Dordick
AbstractSoybean peroxidase (SBP) has an extremely high melting temperature of 90.5 °C at pH 8.0 in the presence of 1 mM CaCl2. The enzyme is substantially more thermostable than the peroxidases from horseradish (HRP) and Coprinus cinereus (CIP). SBP denaturation does not precisely fit the two‐state denaturation model ...... hiện toàn bộ

Biosorption of Heavy Metals
Biotechnology Progress - Tập 11 Số 3 - Trang 235-250 - 1995
Bohumil Volesky, Z. Holan
AbstractOnly within the past decade has the potential of metal biosorption by biomass materials been well established. For economic reasons, of particular interest are abundant biomass types generated as a waste byproduct of large‐scale industrial fermentations or certain metal‐binding algae found in large quantities in the sea. These biomass types serve as a basis...... hiện toàn bộ
