Controlling Of Volatile Gas From Agricultural Organic Waste Material By Microorganism

A method was designed to is ate and screen microarg nism t t can control odor; and one odor-controlling nicroorganism was isolated by this method. Itt, idenUficalion and liquid fermenta an have been researched the controlIit -odor mecharEni and the rela on hip between canb lIing-odor microorganism and some crop . e bl mushroom as well as pathogerE fungus of plant have been tenta vely studied. 500 str ns microorganism were isolated and one odor-conUDlling fungus was screened .TNs fungus 468 can reduce the NH3 enission by c,er.8CFI0, H2S by oi& 50/o and two degrees of odor in fresh chicken manure withotd s rIlz ion. Fungus 468 was identified as Tiodemia teesi and its code name was iF468. The effects of inoculation ,generation-number, subsidiay matenat on the odor coetvlling at ility of F468 were studied; F468 can accelerate innocent passage and impmve totd N in chicken manure. Its liquid seed medium was: 1% gJucose; 1% jcrose; 0.35% yeast ex act0. 1 5%(NH4)2S040.075%KH2PO40.01 %Nad;0.O3%mgso4.7H2O;0.003%1 so4 7H2 0; O.005%cacl2 l i20; 0.0020/ocuso4 H20; ph6.5; tan erature 28C.. medium volume 60mll25Ornlrotation weed lQOrpm.Its Hquid ermeng medium was 1 %starch;1%sucrose; I %yeast fract0.4%(N1i4)2SO4 0.075%KH2PQ4 0.01 %nacl; 0.03%Mgso4 7H20: 0.003%Feso4 7H20; 0.0050/.cad, 2I O 0.002% iso4 5H20: ph6.5; temperature 28C.. medium volume 60rnh/250n ;rota n Weed 100rpm. IVs medium and natured or denatured mateii from internal aid external cell had no odor-controlmg abllty.F468 could restrain the H2S bacterium ,redu the H2S emission and two degrees of odor in fresh chicken mamna . This. was one obr- ntroIhng mechanism of F468. F488 could produce cl\Cx enzyme ;whle No3 bacterium cetid not produce C1\ Cx enzyme and had no odor-controlling ability microorganism ablty of producing C1\Cx enzyme had no su cient and essential relatonslup with irs ability oodor-coritrolling. F468 had competitive effect on edibie rTwshroom and patl genic fungus in plate expe mentits fermented broth had no such effect. It patboganic e1 ct on the crops such as wheat and rice was not found.
