Batch to batch variation study for biodiesel production by hydrothermal carbon catalyst: preparation, characterization and its application

Comparison between batch and fed-batch production of rhamnolipid by Pseudomonas aeruginosa

This paper presents a comparison between batch and three different sets of fed batch fermentations forrhamnolipid production by Pseudomonas aeruginosa. The batch run was performed with 500 ml of culturemedium having the initial glycerol and sodium nitrate concentrations of 30 and 8.3 g/l, respectively. For a fedbatch run with nitrogen source in feed, 250 ml of the nitrogen exc...

A STUDY ON CLAVULANIC ACID PRODUCTION BY Streptomyces clavuligerus IN BATCH, FED-BATCH AND CONTINUOUS PROCESSES

Clavulanic acid (CA) is a potent inhibitor of β-lactamases, enzymes that are responsible for the hydrolysis of β-lactam antibiotics. It is a secondary metabolite produced by the filamentous aerobic bacterium Streptomyces clavuligerus in submerged cultivations. In the present work clavulanic acid production in batch, fed-batch and continuous bioreactors was studied with the objective of increasi...

Segmented linear modeling of CHO fed‐batch culture and its application to large scale production

We describe a systematic approach to model CHO metabolism during biopharmaceutical production across a wide range of cell culture conditions. To this end, we applied the metabolic steady state concept. We analyzed and modeled the production rates of metabolites as a function of the specific growth rate. First, the total number of metabolic steady state phases and the location of the breakpoints...

Application of the Plackett-Burman Statistical Design to Optimize Poly(β-hydroxybutyrate) Production by Ralstonia eutropha in Batch Culture

Small-Scale Batch Fabrication and Characterization of Carbon Nanofiber Probes

Due to their high aspect ratios, nanoscale tip radii, high chemical stability and high mechanical strength, carbon nanotubes (CNTs [1]) and carbon nanofibers (CNFs) are thought to be an ideal probe for scanning probe microscopes (SPMs). Thus, much effort has been devoted to fabricate CNTor CNF-based SPM probes since the discovery of CNTs [2]. Nevertheless, the batch fabrication of CNTor CNF-tip...
