    • The microfiltration of a turbid liquid, especially the microfiltration of a fermentation liquid to recover beer from a suspension containing excess yeast is controlled by measuring a flow velocity (v) and a pressure drop (.DELTA.p) and calculating from the flow velocity (v) and the pressure drop (.DELTA.p) by an apparatus-characteristic function F (v, .DELTA.p) containing the flow velocity (v) and pressure drop (.DELTA.p) as variables a value of concentration of the turbidity-producing solids in the retentate stream. The value of the concentration as thus determined forms an actual value which is compared with a setpoint value of the concentration to determine a difference which is used to control the rate at which the concentrate stream is withdrawn from the retentate stream.

    • A continuous fermentation process is performed in an apparatus system having at least two circulation fermenters arranged in a cascade. Fresh must is introduced into a first fermenter for fermentation with a flocculating yeast, growth of the yeast in the first fermenter being promoted by introduction of oxygen. The fermenting must and yeast are transferred from the first fermenter to a second fermenter and then to any subsequent fermenters of the cascade serially. In the second and any subsequent fermenters, the growth of yeast is inhibited. After passing through the last fermenter of the cascade, be it the second or a subsequent fermenter, yeast is separated from fermented must, and the separated yeast is removed from the system and is not recycled.
    • 在具有至少两个循环发酵机级联的装置系统中进行连续发酵过程。 将新鲜食物引入用于用絮凝酵母发酵的第一发酵罐中,通过引入氧来促进第一发酵罐中酵母的生长。 发酵必须和酵母从第一发酵罐转移到第二发酵罐,然后连续地转移到任何后续的级联发酵罐中。 在第二和任何随后的发酵罐中,酵母的生长被抑制。 在通过级联的最后一个发酵罐之后,无论是第二个或随后的发酵罐,将酵母与发酵罐分离,并将分离的酵母从系统中除去并且不被再循环。

    • A novel mixture of starch-degrading enzymes is produced by a strain of Cladosporium resinae (Strain ATCC No. 20495). One component of this mixture is a novel exo-.alpha.-glucanase (exo-pullulanase). The enzyme mixture is prepared by culturing the microorganism and recovering the enzyme mixture from the medium after removal of grown cells. Exopullulanase can be isolated by fractionation of the mixture. Both the mixture and the exo-pullulanase can be used in the manufacture of dextrose from starch, and alone or in conjunction with appropriate other starch-degrading enzymes, in the production of specific starch conversion products, including fructose syrups. Both the mixture and the exo-pullulanase can also be used for increasing the fermentability of high DE starch conversion products, for example, in production of low calorie alcoholic beverages.
    • 淀粉降解酶的新型混合物是由Cladosporium resinae菌株(菌株ATCC No.20495)产生的。 该混合物的一个组分是新的外切α-葡聚糖酶(外切链酶)。 通过培养微生物并在除去生长的细胞后从培养基中回收酶混合物来制备酶混合物。 可以通过混合物的分级分离外泌尿蛋白酶。 混合物和外支链淀粉酶都可用于制造淀粉中的葡萄糖,并且可以单独使用或与适当的其它淀粉降解酶结合使用,以生产特定的淀粉转化产物,包括果糖糖浆。 混合物和外支链淀粉酶也可以用于增加高DE淀粉转化产物的发酵能力,例如生产低热量酒精饮料。
