4.5 Due to the specificity of mould type manufacturing of centrifugal falcon tubes, the helical structure of the screw caps screw thread can vary, and, given the vigorous mixing conditions, the liquid can spill if the tube is not closed tightly. Tubes can be faulty and the liquid spillage is possible approximately 1 out of 60 tubes. Before launching the experiment and leaving the device, tubes must be checked for liquid spillage occurring in a period of at least 2 minutes at 2000 RPM and 1 s-1 Reverse Spin Interval (RSI) with a closed lid. If droplets of liquid will appear on the inner surface of the lid, then the screw cap is faulty and the tube must be replaced.
4.6 Change of optical characteristics of the tube depending on temperature: When temperature of the plastic material is changing, i.e. during temperature change of 30°C every hour, the plastic material of the tube changes optical characteristics in a range of ±0.1 OD600.

5. Calibration

5.1
5.2 5.2.1
5.2.2

Calibration verification. The device is software calibrated with E.coli BL21 or S.Cerevisiae wild strain cell suspensions for operation with TPP TubeSpin® Bioreac-
tor 50ml tube at temperature range from +15°C to +60°C.
To verify the conformity of calibration follow the subsequent procedures: Connect the device to the computer, launch the software and select factory calibration; Take a TPP TubeSpin® Bioreactor 50ml tube; Add 10 ± 0.1 ml distilled water; Close the cap of the tube thoroughly; Insert the tube into the socket; Set the measurement interval (MI) to 1 minute; Press the Play button in the software; The device will start measuring in 1 minute and should complete after 30--60 seconds and OD value should appear on the display and software; If OD value equals 0 (±0.1 OD) then the device corresponds to factory pre-calibration settings and is suitable for use.
Creating user calibration Get cell suspension samples in 50 ml falcon tubes with typical optical densities of your experiments. If the maximal OD of your experiment (stationary phase) is 5 OD600 then the recommended samples are 0 (ddH2O water or broth media) 1, 2, 3, 4, 5, 6 OD600. Measure OD at desired wavelength of each cell suspension using a spectrophotometer with proper prior dilutions. The proportionality between OD600 and cell density exists only for OD600  0.4 (approximately), we recommend diluting samples to the range of 0.1-0.2 OD. Multiply the dilution factor values to get the OD of the samples. Continue to software manual page 29. RTS-8 can be calibrated to detect scattered light of any possible cell with any possible shape and size, but due to difference of light scattering in various cell suspensions,
we cannot guarantee the stated measurement range in all conditions.

6. Operation

Recommendations during operation

· Remove the falcon tube from the tube socket before connecting or disconnecting the

external power supply during operation.

· Start operation approximately 15 minutes after switching on

the device (some time is necessary for stabilization in the

working mode).

· Tube positioning in the tube socket must be as follows: The

volumes mark of the TPP tube must be between and opposite

to the two markings on the rotor (figure 3); this position ena-

bles the light from the laser to be transmitted without disruption by different marks presented on the tubes outer surface.

6.2 Turn on the unit by pressing the power switch on the rear panel (fig. 1/1).

Note. After turning on the unit starts heating and continues to maintain the temperature regardless of other operations.
6.3 Insert the tube into the sockets. 6.4 Software control mode. Switch on the computer with installed software and continue
working according to software operation manual.

Note. While the unit is controlled by PC, front panel keys are limited in functions, only Run Stop key functions. The display of the unit shows "RTS-8 controlled by PC".
6.5 Manual mode. 6.5.1 Press the Select key (fig. 2/1) to activate the possibility to change to an individual
channel or to a parameter (the channel box or parameter will be highlighted and blinking). Selected channel box will remain blinking all the time while the device is on. Indications of colors of boxes are the following: · Brown when channels are not operating. · Yellow when a channel is actively selected by Select key (lasting 10 seconds) which allows to switch between channels. · Green when channels are in operation, · Purple when preSens module is operating. 6.5.2 Use  and  keys (fig. 2/2) to change to an individual channel or set the necessary value (the box will be highlighted and blinking). 6.5.3 It is possible to set by  and  keys time between optical density measurements ­ MI, channel selection, spinning speed (RPM), temperature (°C), temperature control (on/off), Reverse Spins Interval (RSI). 6.5.4 Press the Run Stop key (fig. 2/3) to start and stop operation.

Caution! Operation stop will not stop the heating process. To stop heating process set temperature has to be decreased manually until "off" indication appears.

8. Recommendations for creating personal settings for cultivation of microorganisms. Points to consider
8.1 Temperature distribution specifics (psychrophiles, mesophiles, thermophiles). The optimal growth temperatures of microorganisms are divided in three principal groups (see fig. 4):
· Psychrophiles (I) ­ obligate (1) and facultative (2); · Mesophiles (II); · Thermophiles (III) ­ thermotolerant (3), facultative (4), obligate (5) and extremophile (6).
Thick line mark represents optimal growth temperature.

Figure 4. Temperature boarders and optimal growth zones of prokaryotes and their classification.

8.1.1
8.1.2 8.1.3 8.2
8.2.1

For psychrophiles, that are cultivated at temperatures of 15°C +-2°C below ambient the device must be installed in a cold room or a refrigerated chamber. Despite the active cooling of the device, the actual temperature of the reactor will always differ from the actual temperature of the sample because of its rotation. For mesophilic microorganisms, the device can be situated at room temperature. For thermophilic microorganisms, the device can be situated at room temperature.
Cell growth depending on rotation intensity. It is known that aeration affects the growth and growth rate of aerobic microorganisms. The RSI and RPM affect the rate of oxygen uptake in the bioreactor. Results obtained in fig. 5 and fig. 6 indicate that the maximum rate of cell division is detected at RSI of 1 s-1 at a speed of 2700 rpm. The increase of pause between reverse spins reduces cell growth rate and OD yield, reaching ~44% of the maximum value (RSI 1 s-1), when RSI is 8 s-1.
Legend of experiment (fig. 5.): Multi-channel bioreactor RTS-8 was used with 850 nm laser, volume of Terrific Broth (TB) in 50 ml Falcon tube was 10 ml, RSI 1, 2, 4, 8 s1, MI 10 min, RPM 2000, temperature 37° C, TPP Bioreactor vessels.

Figure 6. Influence of Interval of Reverse Spinning and RPM on the Growth kinetics (OD=600nm/t) vs Time of fermentation (h).
8.3 Aeration and types of recommended tubes. For aerobic microorganisms, it is recommended to use tubes that are supplied by TPP - TubeSpin® Bioreactor 50 ml. For obtaining optimal results growing aerotolerant anaerobes, it is required to seal the screw cap of TPP TubeSpin® Bioreactor 50 ml by tape or use TPP 50 ml falcon tubes that are available without air vents. User can also use standard centrifuge tubes of 50 ml Falcon type, taking into account that the tube material will be as transparent as TPP TubeSpin® Bioreactor tube or must create user calibration.
8.4 The cells that are used for factory calibration are E.coli BL21 (freshly grown using TB medium overnight) or S.Cerevisiae wild strain (freshly grown using YPD medium overnight).
14

8.5 Factory calibration growth phase influence on achievable user calibration measurement error. During the growth transition of cells from the exponential growth to the stationary phase, a number of morphological and physiological changes take place, including cell volume decrease and cell shape change. Therefore, if cells are taken for referent measurement using spectrophotometer at different stages from stationary phase then the correctness of measurement can be worse than specified. Moreover, OD measurement results of spectrophotometers differ from one another and depend on the optical configuration such as aperture size for example. Therefore, it is a requirement for application of the same spectrophotometer OD measurement for results repeatability.
8.6 User calibration. Calibration depends on the cell size and volume. Calibration from one type of microorganism cannot be used accurately for other type microorganism of other size and shape. The device can be calibrated at desired reference wavelength to meet the needs of the user, yet the full specified measurement range cannot be guaranteed. The factory calibrations are performed using E.coli BL21 (stationary phase) and S.Cerevisiae wild strain cells (stationary phase).
