Effect of Shaking Speed and Type of Closure on Shake Flask Cultures [PDF]
Growth of microorganisms and biosynthesis of microbial products in shake flasks may be limited by operating conditions which provide inadequate supplies of oxygen. Methods are described for meeting the oxygen requirements of test organisms by using standard baffled flasks with pad-type closures and shaking at relatively high speeds. Growth

Levan Production in Shake Flask and Fermenter Influence of Feeding Strategy on Levan Yield and Molecular Weight Distribution [PDF]
Effect of feeding strategy on levan production was studied in a shake flask and a 5 L lab scale fermenter. In a shake flask, levan specific substrate yield (YP/S) increased from 0.35 g levan/g sucrose to 0.48 g levan/g sucrose with repeated batch feeding.

View on a mechanistic model of Chlorella vulgaris in incubated shake flasks [PDF]
Abstract Kinetic growth models are a useful tool for a better understanding of microalgal cultivation and for optimizing cultivation conditions. The evaluation of such models requires experimental data that is laborious to generate in bioreactor settings. The experimental shake flask setting used in this study allows to

Breeding of a High-Yield Glutathione-Producing Strain by Atmospheric and Room Temperature Plasma Mutagenesis and Microbial Microdroplet Culture System [PDF]
In order to improve the ability of a wild-type strain (BY-1) of Pichia pastoris to produce glutathione (GSH), a mutant strain designated BY-1-26 was obtained by atmospheric and room temperature plasma (ARTP) mutagenesis. To further improve the production
