45 results about "Euglena gracilis" patented technology

Euglena gracilis is a freshwater species of single-celled alga in the genus Euglena. It has secondary chloroplasts, and is a mixotroph able to feed by photosynthesis or phagocytosis. It has a highly flexible cell surface, allowing it to change shape from a thin cell up to 100 µm long, to a sphere of approximately 20 µm. Each cell has two flagella, only one of which emerges from the flagellar pocket (reservoir) in the anterior of the cell, and can move by swimming, or by so-called "euglenoid" movement across surfaces. E. gracilis has been used extensively in the laboratory as a model organism, particularly for studying cell biology and biochemistry.

Method for detecting potential inherent toxicity of organic pollutants in water body

The invention discloses a method for detecting potential inherent toxicity of organic pollutants in a water body, which comprises the following steps: using resin to perform enrichment of water samples first; and applying a comet assay of Euglena gracilis to research the inherent toxicity of the organic pollutants in the water body. The key technique lies in the innovation of glue manufacturing process, namely adopting fractioning at a first layer, then adopting the conventional 'sandwich' glue manufacturing method, and manufacturing the glue by using a normal melting point glue with a higher melting point at a third layer, thus the defect that a rubber plate in the conventional method is easy to damage is overcome. By performing optimization research on cracking time and electrophoresis conditions of algae comets, a perfect image result is obtained. At present, the method for detecting the potential inherent toxicity of the organic pollutants in the water body through algae single cell gel electrophoresis (SCGE) is not reported, and algae are applied to the SCGE to widen the research objects of the SCGE.

Culture medium of euglena gracilis and open type high-density culture method

The invention provides a culture medium of euglena gracilis, which is added with different inorganic nutrient substances, in particular to nutrient components such as a mixture of ammonium chloride and urea, and the like. In an open culture process, the culture medium not only overcomes the defects that euglena gracilis is easy to pollute by microorganisms and bacteria so as to pollute the environment, and the like in the prior art, but also can ensure that the euglena gracilis quickly utilizes the inorganic nutrient components to accelerate cell division under the condition of not adding an organic carbon source. The culture medium of the invention shortens the grown cycle of the euglena gracilis by 2-5 days compared with a conventional culture medium and has a biomass accumulation being 1-1.5 times higher than the conventional culture medium. The culture medium removes the organic carbon source of the conventional culture medium and supplements the carbon source in the mode of CO2, thus the culture medium not only can achieve the purpose of avoiding microorganism pollution, but also can increase the capacity of absorbing the CO2 of the euglena gracilis. In the process of the mass production and culture of the euglena gracilis, the culture medium can adsorb a large amount of industrial CO2 waste gas, thereby having important meaning to energy saving, emission reduction and environmental protection.
