Method for collecting biological material and device for collecting biological material
Provided is a device for collecting biological material from a microbe, the device including: a collection container that is used to collect a microbe from a liquid sample containing the microbe and to extract the biological material from the microbe; and a temperature control mechanism that controls a temperature of the collection container. Herein, the temperature control mechanism controls a temperature of the collection container so that the microbe is collected at a first temperature and the biological material is extracted from the microbe at a second temperature higher than the first temperature.
1. A device for collecting ATP from a microbe, comprising:
a collection container that is used to collect a microbe from a medium containing the microbe and to extract the ATP from the microbe; and
a temperature control mechanism comprising a heating unit configured to heat the collection container, a temperature sensor configured to detect a temperature of the collection container and output temperature detection signals based on the temperature of the collection container, and a temperature controller having control logic configured to:
i) control the heating unit to heat the medium containing the microbe in the collection container to a predetermined first temperature set from 30° C. to less than 40° C. to collect the microbe from the medium at the first temperature while suppressing a decrease in bioactivity of the microbe based on the temperature detection signals outputted from the temperature sensor, and then keep the temperature at the first temperature to eliminate free ATP present outside the microbe based on the temperature detection signals outputted from the temperature sensor;
ii) raise the temperature of the collection container to a predetermined second temperature that is higher than the first temperature to extract ATP from the microbe at the second temperature based on the temperature detection signals outputted from the temperature sensor; and
iii) lower the temperature of the collection container back to the first temperature to collect a predetermined amount of ATP extract based on the temperature detection signals outputted from the temperature sensor.
2. The device for collecting ATP from a microbe according to claim 1 , wherein the temperature controller has further control logic configured to maintain the temperature of the collection container at the first temperature for a predetermined time while the predetermined amount of ATP extract is collected based on the temperature detection signals outputted from the temperature sensor.
