λ Vectors for Stable Cloned Gene ExpressionAbstract The 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... ...

A Computer Model Based on Reaction‐Diffusion Equations for the Growth of Filamentous Fungi on Solid SubstrateAbstract A model of two reaction‐diffusion equations for biomass production and glucose consumption was developed. Experiments were carried out in order to estimate the different constants of the model and to compare the behavior of the system using two species of fungi, Rhizopus oligosporus and Trichoderma viride T.S....

Process Design and Costing of Bioethanol Technology: A Tool for Determining the Status and Direction of Research and DevelopmentAbstract Bioethanol 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... ...

Clavulanic Acid Degradation in Streptomyces clavuligerus Fed‐Batch CultivationsAbstract Clavulanic 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... ...

Unusual Thermal Stability of Soybean PeroxidaseAbstract Soybean 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 ... ...

Biocommodity EngineeringAbstract The application of biotechnology to the production of commodity products (fuels, chemicals, and materials) offering benefits in terms of sustainable resource supply and environmental quality is an emergent area of intellectual endeavor and industrial practice with great promise. Such “biocommodity engineering” is distinct from biotechnology motivated by hea... ...
