对几种饲料植物，特别是卢塞恩、红三叶草和梯牧草的不同成熟阶段的表面微生物区系进行了研究。有没有显着的增加，直到后期的总计数，和乳酸菌没有发现，直到该阶段后，在该阶段的作物通常会被青贮。它们仅在红三叶草上被发现，并且它们的菌落在琼脂平板上生长微弱。然而，这些生物体，在筒仓中的条件下，发展非常迅速，抑制剂与活的植物相关联的可能性被建议，并有待进一步研究。从表面微生物植物群中分离的几种生物体对从表面植物群中分离的乳酸菌菌株具有拮抗作用，并且在较小程度上对来自青贮饲料的菌株和植物乳杆菌纯菌株具有拮抗作用。[参见美国国防部16（2）134（1954）。斯特林。]在任何阶段的植物上都很少发现厌氧孢子携带者，但样品是经过仔细收集的，没有与土壤接触。急诊室
The surface microflora of several fodder plants, in particular lucerne, red clover and timothy grass, was examined at various stages of maturity of the plant. There was no significant increase in total count until a late stage, and lactic acid bacteria were not found until after the stage at which the crops would normally have been ensiled. They were found only on the red clover, and their colonies grew weakly on the agar plates. These organisms, however, developed very rapidly under the conditions in the silo and the possibility that an inhibitory agent is associated with the living plant is suggested and is to be investigated further. Several of the organisms isolated from the surface microflora were antagonistic to a strain of the lactic acid bacteria isolated from the surface flora and, to a lesser extent, to a strain from silage and a pure strain ofLactobacillus plantarum. [cf.D.S.A. 16 (2) 134 (1954). Stirling.]Very few anaerobic spore-bearers were found on the plants at any stage, but the samples had been carefully harvested and had not been in contact with the soil.
