[2]. This strain has an ampicillin resistance gene (bla) encoded on a plasmid. A concentration of 0.1 g/L ampicillin must be maintained in all cultures, since absence or low concentrations of ampicillin will result in plasmid loss [3]. Therefore, from inoculum preparation in shake flasks to fermentation runs in 3 L vessels, we always added 0.1 g/L

Leachables and extractables are defined as substances that can either be extracted from plastic materials under harsh conditions (e.g. extreme temperatures, presence of solvent) or released spontaneously under standard conditions. They may originate from compounds used in polymer manufacturing such as softeners, stabilizers, and antioxidants. Espe-

Power number (Np) The (impeller) power number (also known as Newton number) is a dimensionless number associated with different type of impellers. Np is commonly used to calculate impeller power consumption during bioprocess scale-up [2]. We determined the power number and P/V values at various Used with 1 L fermentation glass vessel Used with 10 L

The stirred-tank bioreactor design is relatively easy to describe with classical engineering approaches (Figure 1). Parameters to describe this vessel geometry include impeller diameter, vessel diameter, liquid height, and ratios thereof. It is the bioreactor design for which most research on Figure 1: Stirred-tank bioreactor design d D i h ...

Lab Exercise 3: Media, incubation, and aseptic technique

Cultivation chambers called incubators are used to grow microbes at a range of temperatures. In this lab, we have set incubators for two temperatures most commonly used as optimum temperatures by the microbes we work with: 25° C and 37° C. We also have an incubator set at 4° C (aka a refrigerator!) that
