Device and method for collecting euglenophyta in field

Abstract

The invention belongs to the field of algae collection, and particularly relates to a device and method for collecting euglenophyta in the field. The portable device for collecting the euglenophyta inthe field is characterized by comprising a hollow tube body, a tube cover matched with the hollow tube body, a pick-and-place rod, wherein a water absorbing collector is fixed to one end of the pick-and-place rod, and the pick-and-place rod is placed in the hollow tube body. The invention further provides a method for collecting the euglenophyta in the field. The collected euglenophyta is adsorbed on the water absorbing collector for sampling conveniently; in addition, the water absorbing collector can enable the euglenophyta to be unable to swim in the transportation process (a bad environment), and the euglenophyta is fixed in a material; when the euglenophyta is transported to a laboratory, a proper amount of culture medium is added to a centrifuge tube, light is given, a favorable environment is restored, the swimming capacity of the euglenophyta is enhanced, and the euglenophyta swims from the water absorbing collector to the culture medium and grows massively.

Description

technical field [0001] The invention belongs to the field of algae collection, in particular to a device and method for collecting euglena in the field. Background technique [0002] Euglena is a creature that has multiplied on the earth 500 million years ago. It has no cell wall and can swim. It is a kind of "protozoa". It has both animal and plant characteristics. Euglena is the best experimental material for studying endosymbiosis, chloroplast development and photosynthesis. At the same time, euglena has high commercial value. On October 30, 2013, the National Health and Family Planning Commission's "Announcement on the Approval of 8 New Food Raw Materials including Euglena" (No. 10, 2013) approved Euglena as a new food raw material. Euglena is rich in nutrients: vitamins, mineral nutrients, amino acids, unsaturated fatty acids, chlorophyll, lutein, zeaxanthin, GABA and other 59 kinds of nutrients that are necessary for the human body every day, all of which are indisp...

AI Technical Summary

Problems solved by technology

[0005] The existing field collection equipment for euglena is rough and requires professional operation, which is difficult to meet the requirements of fast mailing. Even if it can be sent, it cannot be transported by air, but can only be transported by land. It takes a long time and will lead to the failure to control the temperature, light and other algae in the middle Problems such as growth conditions will cause different degrees of damage to water samples (smelly water samples, large-scale reproduction of bacteria, outbreaks of other dominant species, etc.) and lose research value
