Space biology and biotechnology

PLAZMIDA Experiment

Objective:

Investigation of microgravity effect on the rate of transfer and mobilization of bacteria plasmids.

Tasks:

• Study of conjugation and mobilization process in space.
• Assessment of the effect of space flight factors on plasmid DNA transfer rate.

Science Hardware Used:

• Thermal container Biocont-T, including:
  • Hybridizers Recomb-K
  • Kit with tubes
• Thermally insulated refrigerator Kriogem-03M

Flight Equipment Used:

• Refrigerator Kriogem-03M

Experiment Results:

• Hybridizers Recomb-K with obtained hybrid microorganism strains
• Kit with tubes with the broth cultures of investigated microorganisms
• Temperature values recorded by a self-contained temperature data logger with a specified time interval.

Expected Results:

Development of a model of gravity effect on conjugation processes and acquisition of new data on mobilization of extrachromosomal heredity factors.
