In 1943 there appeared in Berichte der Deutschen Chemischen Gesellschaft[1] a brief notice (Figure 1) of the death of Wilhelm Schlenk, the former President of the German Chemical Society (Deutsche Chemische Gesellschaft).[2a] It was stated that a fuller biography of Schlenk would appear later, but this has not been forthcoming, although there were short articles in specialized Austrian[2b] and ...
Gerhardt, Philipp (The University of Michigan, Ann Arbor), and D. M. Gallup. Dialysis flask for concentrated culture of microorganisms. J. Bacteriol 86:919-929. 1963.-A twin-chambered dialysis flask was designed with a supported membrane clamped between a reservoir of medium in the bottom and a small volume of culture above, the unit being mounted on a shaking machine to provide aeration and ag...
We demonstrated that a Klura3Δ, mutant of the yeast Kluyveromyces lactis is able to produce and secrete into the growth medium considerable amounts of orotic acid. Using yeast extract-peptone-glucose (YPD) based media we optimized production conditions in flask and bioreactor cultures. With cells grown in YPD 5% glucose medium, the best production in flask was obtained with a 1:12.5 ratio for f...
[1] Automated flask sampling aboard small charter aircraft has been proposed as a lowcost, reliable method to greatly increase the density of measurements of CO2 mixing ratios in continental regions in order to provide data for assessment of global and regional CO2 budgets. We use data from the CO2 Budget and Rectification-Airborne 2000 campaign over North America to study the feasibility of us...
BACKGROUND Generation of an effective dendritic cell (DC) based cancer vaccine depends on appropriate differentiation of monocytes in vitro. OBJECTIVE To compare the effects of monocyte separation methods, flask adherence (Flask-DC) and magnetic activated cell sorting (MACS-DC), on phenotypic and functional characteristics of resultant DCs. METHODS DCs from healthy volunteers were generated...
A simple and convenient method for culturing anaerobic bacteria is described. Cultures can be grown in commercially available flasks normally used for preparation of sterile external solutions. A special disposable rubber flask closure maintains anaerobic conditions in the flask after autoclaving. Growth of a variety of anaerobic oral bacteria was comparable to that obtained after anaerobic inc...
