Recently, American scientists successfully used forage grass as a raw material to produce bioethanol, and the production cost was low. The quality of produced bioethanol was also satisfactory.
This research was completed by scientists from the University of Nebraska and the U.S. Department of Agriculture's research center for five years. The research results have been published in the new issue of the National Academy of Sciences.
According to Ken Vogel, a professor at the University of Nebraska who participated in the study, scientists experimented with forages grown on farms in Nebraska, South Dakota, and North Dakota. The results showed that an average of 1 hectare of pasture About 2800 liters of bioethanol can be produced, while approximately 3270 liters of bioethanol can be extracted using the same area of ​​corn.
Vogel pointed out that in terms of unit area, the amount of bioethanol extracted from pasture is less than that of corn, but the cost of pasture is much lower than that of corn, and the quality of produced bioethanol is not much different, so this research result will be The development and utilization of new biofuels are of great significance.
According to the adherence requirements of the product, cells are divided into three categories:
Suitable for suspension culture of common cells and tissues;
The standard type has good cell adhesion performance and is suitable for cell adhesion growth;
Dedicated containing cell pastes (cell clusters that can be used in some special cases, such as cell walls, cell surfaces and secretory cells).
According to the shape of the instrument, it is divided into:
Wide body culture flask;
triangle bottle;
Torticollis flask.
cell culture flask,filter cap cell culture flask,suspension culture flasks,cell tissue culture flask
