The principle of the present invention：
Yeast cells nutrient solution (flocculating yeast nutrient solution i.e. above) is using water as solvent, a small amount of grape by adding
The nutriments such as sugar maintain the growth of cell.Yeast metabolism formaldehyde generates carbon dioxide and water, and the secondary of formaldehyde will not be brought to release
Put.Thus, it can effectively be absorbed using yeast cells nutrient solution and remove formaldehyde gas.At present, the research of flocculating yeast has been
The preliminary progress through having.Shown according to existing result, the flocculation of yeast is mainly by gene of flocculating (Flocculation
Genes, FLO) control, flocculation and the solution of yeast cells can be regulated and controled by the expression for regulating and controlling FLO1, FLO5, FLO11 gene
Wadding.Wherein, the flocculation of the flocculating yeast of flo1 types is mainly based upon between the mannose residue on its surface and protein and can formed
Hydrogen bond.Flocculation albumen on yeast cell wall, under conditions of calcium ion presence, and the mannose on other yeast cell walls is residual
Base specific binding result in Yeast Flocculation, and the effect of calcium ion is flocculation albumen is kept correct conformation.When to flocculation ferment
Ca is added in female nutrient solution2+When, due to the connection function of calcium bridge, the flocculation of yeast can be reinforced；And when addition EDTA or lemon
During lemon acid sodium, Ca2+It is removed, solution wadding occurs for yeast cells.Or when adding the glucides such as mannose, free mannose
Meeting and the protein on the mannose competition binding flocculating yeast surface of yeast cell surface so that flocculation weakens, yeast cells hair
Raw solution wadding.So, by adding Ca2+Solution, EDTA, sodium citrate or mannose can manual control yeast cells flocculation
Whether, this changes for the material of yeast and laid the foundation.
Oxidation-reduction potential (ORP) is the ability of solution receiving and losing electrons, and unit is used as with millivolt (millivolt, mV).
ORP value height represent solution obtain electronic capability it is stronger, in the state of oxidation；ORP value is low to represent the ability increasing that solution provides electronics
By force, it is reducing condition.Extracellular ORP value can as intracellular electro transfer and redox equilibrium net result reflection, ORP prison
Control system includes a sensor and a reference electrode, and sensor is made up of inert metal (such as platinum, rhodium, iridium, gold), and reference
Electrode is typically Ag/AgCl.The activity of yeast cells in nutrient solution can be reflected by the height of ORP levels.
A kind of flocculating yeast cell is the present invention relates to the use of, is attached to by it on porous membrane, formaldehyde in air is entered
Row is effectively absorbed and is metabolized.Monitor the growth conditions of yeast cells in real time with ORP monitoring systems.The flocculating yeast cell is one
