  1. 1. Effects of high sugar concentrations in production scale bioreactor : a scale-down study of s. cervisiae

    Författare :Stefan George; KTH; []
    Nyckelord :;

    Sammanfattning : Substrate concentration gradients exist in large-scalebioreactors, due to a combination of insufficient mass transferand mixing, and microbial activities. Zones with high substrateconcentration may arise close to a feed point. It is largelyunknown to what extent these gradients influence themicroorganisms and what the microbial response might be.

  3. 2. Tools and applications to assess yeast physiology and robustness in bioprocesses: Lab-scale methods from single cells to populations

    Författare :Luca Torello Pianale; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Scale-up; fluorescence; scale-down; Saccharomyces cerevisiae; biosensors; microfluidics; bioproduction;

    Sammanfattning : Bioprocesses enable the efficient production of valuable chemicals by microorganisms such as the yeast Saccharomyces cerevisiae . Predictable and stochastic perturbations affect microbial performance in an industrial-scale bioreactor. LÄS MER

  5. 4. Metabolic responses ofPseudomonas stutzeriandEscherichia colisubjected to starvation and surplus of carbon/energy substrates in bioreactors

    Författare :Bo Xu; KTH; []
    Nyckelord :;

    Sammanfattning : Transient nitrite accumulation during anaerobicdenitrification is a widespread phenomenon for manydenitrifying bacteria includingPseudomonasstutzeri. Nitrate starvation caused the degradation ofthe second denitrifying enzyme nitrite reductase (NiR) inP.stutzeri. LÄS MER

  7. 5. Deployment Simulations of a Composite Boom for Small Satellites

    Författare :Pau Mallol Parera; Gunnar Tibert; Keith Seffen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; small satellites; deployable structures; high packaging ratio; composites; bi-stable; gravity off-loading system; små satelliter; utfällbara strukturer; kompakt ihoppackning; kompositer; bistabil; tyngdkraftskompenserande system;

    Sammanfattning : The use of small satellites is rapidly growing, especially satellites with masses between 1 and 10 kg and few litres of volume. The main reasons are due to the low development time and cost. Electronics miniaturization and high density integration is enabling the small satellites class to perform more and better tasks and at a lower cost. LÄS MER
