SFR SHAKE FLASK READER & SFR VARIO Biomass, O2 & pH Monitoring During Diauxic Growth of E. coli Yeast Growth Phases in Complex Medium E. coli K12 shows distinct diauxic growth in medium containing glucose and lactose, here monitored with the SFR vario. In the first growth phase glucose is consumed, which is indicated by a decrease in oxygen concentration (1). When glucose becomes limiting, growth stops showing in a small plateau in biomass measurements (2). The bacteria adjust their metabolism to lactose. In the third phase E. coli grow on lactose until it is consumed and turns into the...

Optical Sensor Systems systems SDR SensorDish® Reader Online Culture Monitoring of O2 & pH in Multiwell Plates The SDR SensorDish® Reader is a small 24-channel reader for non-invasive detection of oxygen and pH in multidishes (SensorDishes®). These multidishes contain a sensor spot at the bottom of each well and are read out non-invasively through the transparent bottom. SensorDishes® for oxygen (OxoDish®) and pH (HydroDish®) are available in 24- and 6-well format. Deep well plates with integrated oxygen (OxoDish®-DW) or pH sensors (HydroDish®-DW) allow measurements in shaken cultures....

More Security for Hypoxic Stem Cell Cultivation Oxygen & pH Monitoring in Tissue Engineering The influence of medium change on dissolved oxygen (DO) during cultivation of human embryonic stem cells (hESC) was investigated at different oxygen tensions in the incubator atmosphere. Samples with full medium change using not pre-calibrated medium showed a DO increase of 20 – 60 % air saturation. Other than expected, even half medium change with pre-incubated medium resulted in a notable DO increase of 10 – 30 % air saturation. Human chondrocytes with different start cell concentrations were...
