Abstract

The invention discloses a device for microalgae phototropism research. The device comprises a pedestal, a culture dish, shading partitions, a support seat, a support bar 1, an adjusting screw barrel, a regulating lever 2, a horizon bar, a wavelength adjustment assembly and a light source. The influence of lighting on the microalgae distribution can be judged according to the relationship between the algae distribution and light. The device can implement the change of the wavelength of the light source, and can also implement the change of the intensity of the light source, thereby greatly enhancing the accuracy and convenience for microalgae and lighting research. When the wavelength is changed, the wavelength can be regulated only by rotating the gear. The intensity of the light source can be changed by rotating the adjusting screw barrel. The three shading partitions are arranged to well perform change comparison on lighting adjustment, thereby implementing variable and quantitative research on microalgae.

Description

technical field

[0001] The invention belongs to the technical field of microalgae research, in particular to a device for microalgae phototaxis research and belongs to the field of environmental biology. Background technique

[0002] Microalgae widely exist in various natural water bodies such as rivers, lakes, and wetlands, and play a very important role in the self-purification process of natural water bodies. It can effectively remove nutrients in sewage through metabolism (photosynthesis) at low cost. Especially the nitrogen and phosphorus nutrients that can cause eutrophication in lakes and other water bodies, thereby promoting their own proliferation, and they have many potential application values ​​[lm1], which can produce good environmental and economic benefits.

[0003] Microalgae in natural water can be divided into suspended state (planktonic microorganisms) and community attached state (natural water algae biofilm) according to their morphological characteristi...
