Abstract:
The mothod for degrading plant toxin by using microorganism is presented. Thus Pseudomonas sp. Pt-II capable of degrading plant toxin is isolated from soil. The cultural broth of pseudomonas sp. Pt-II inhibit the growth of stachybotris chatarium which degrade (s) organic matter and then produces plant toxin. The above cultural broth of Pseudomonas sp. Pt-II is prepared by adding peat, zeolite, diatomite or pulplite into Na(CMC) and inoculating the mixture with pseudomonas sp.Pt-II.
Abstract:
The method measures a quantity of dew in vinyl plastic house using methylred+Boromthymolblue solution, checks generation of NH3 or NO2 gases using discoloration paper, and determines their toxity to the farm products. If toxic gases are checked out, ventilation of window opening protects damage of farm products.
