Morphology, ultrastructure and mating of sporidia of a wheat-bunt fungus, Tilletia caries (DC.) Tul.

Creator:: Kollmorgen, James Frederick
Abstract:: The teliospore of Tilletia caries germinates to produce a promycelium with a whorl of primary sporidia at its tip. The time between emergence of the promycelium and the development of primary sporidia averaged 2.3 h. Fusion between compatible sporidia occurred within an additional 3.8 h. Primary sporidia appeared to be...

Effect of sucrose on the production of flavor compounds by yogurt culture bacteria

Creator:: Yang, Chang-su
Abstract:: Organoleptically, flavored yogurts appear to contain lower levels of acetaldehyde than plain yogurt. This study was undertaken to seek the reasons for this phenomenon by focusing on the analyses of acetaldehyde production by yogurt culture bacteria in yogurt base containing added sucrose and by performing other analyses such as the...

Measurement and interpretation of physical properties of soils

Creator:: Nagpal, Narender Kumar, 1942-
Abstract:: One of many important physical properties that must be known to understand transport phenomena in soils is pore size distribution. Presently the pore size distributions of soils are most commonly obtained from soil water characteristic curves. The soil water characteristic curves are usually obtained by the pressure plate technique. It...

Morphology and genesis of Gray Podzolic soils in Thailand

Creator:: Rojanasoonthon, Santhad
Abstract:: Nine Gray Podzolic soils from different physiographic regions of Thailand were studied to determine their characteristics and genesis in relation to their parent materials, land form, pedogenic environment, classification and management. The clay was characterized by X-ray diffraction and standard chemical and physical analyses were performed. Mineralogy of the light...
