Studies on Bacterial Nutrition. v. the Effect of Plant Tissue upon the Growth of Anaerobic Bacilli
In the case of the pneumococcus, a seeding so minute as to cause in dextrose broth a period of bacterial lag extending over 18 hours will amply suffice to induce prompt growth in plain broth to which pieces of sterile unheated potato have been added. The presence of vegetable tissue causes other changes in the configuration of the growth curve. There is a prolongation of both the stationary pha...
متن کاملEffect of airway obstruction upon facial growth.
This article explores both sides of the controversy concerning respiratory behaviors and dentofacial development. The literature is replete with statements that airway impairment alters facial and dental growth, but there also is substantial evidence to the contrary. Much of the confusion stems from the subjective criteria frequently used in defining the terms impairment and mouth breathing. Ad...
متن کاملTHE GROWTH OF DICTYOSTELIUM DISCOIDEUM UPON PATHOGENIC BACTERIAl
Species of the Dictyosteliaceae, a group of pseudoplasmodiumforming slime molds, are not uncommon in nature and can be readily isolated from soils, from decaying vegetation and from the dung of various animals. In contrast to the Myxogastrales which possess true plasmodia, the Dictyosteliaceae are characterized by myxamoebae which retain their identity throughout the whole life cycle of the org...
متن کاملThe Effect of Solid Surfaces upon Bacterial Activity.
The bacterial population of water samples from the sea, lakes or other sources usually increases during storage. While several different factors may be operative (Prescott and Winslow, 1931), it is noteworthy that the magnitude of the increase is often related to the size of the receptacle in which the water is stored. For example, Whipple (1901) found that the bacterial population of water, wh...
