Levan Production in Shake Flask and Fermenter Influence of Feeding Strategy on Levan Yield and Molecular Weight Distribution [PDF]
E3S Web of Conferences, 2023 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.

Breeding of a High-Yield Glutathione-Producing Strain by Atmospheric and Room Temperature Plasma Mutagenesis and Microbial Microdroplet Culture System [PDF]
Shipin Kexue, 2023 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

Hydrophobicity - Shake Flasks, Protein Folding and Drug Discovery [PDF]
Current Topics in Medicinal Chemistry, 2010 Hydrophobic interactions are some of the most important interactions in nature. They are the primary driving force in a number of phenomena. This is mostly an entropic effect and can account for a number of biophysical events such as protein-protein or protein-ligand binding that are of immense importance in drug design.

Shake Flask Biodegradation of 14 Commercial Phthalate Esters [PDF]
Applied and Environmental Microbiology, 1984 An acclimated shake flask CO 2 evolution test was used to study the biodegradability of 14 commercial phthalate esters that are commonly used as plasticizers. Both CO 2 evolution (ultimate biodegradation) and loss of parent phthalate esters (primary biodegradation) were measured.

Effect of Shaking Speed and Type of Closure on Shake Flask Cultures [PDF]
Applied Microbiology, 1969 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

A new wireless system for decentralised measurement of physiological parameters from shake flasks
Microbial Cell Factories, 2006 Background Shake flasks are widely used because of their low price and simple handling. Many researcher are, however, not aware of the physiological consequences of oxygen limitation and substrate overflow metabolism that occur in shake flasks ...
