Age, Growth, and Food Habits of the Largemouthed Black Bass (Micropterus Salmoides) and the Spotted Bass (Micropterus Puctulatus SSP) in North and East Texas Lakes

Description: This study is based on the examinations and analyses of 388 largemouthed black bass (Micropterus salmoides) and 118 spotted black bass (Micropterus puctulatus ssp.) which were collected over a period of three years from 9 lakes in the North-Central and East Texas areas. The results should show the following: (1) the average age of the black bass in each of the nine reservoirs in Texas; (2) the growth rate of the bass in these reservoirs; (3) the feeding habits of the bass in all reservoirs studied; (4) a comparison of the growth rates of the largemouthed and spotted basses; and (5) a comparison of the growth rates of bass from Texas and Oklahoma.

In Vitro Determination of the Cellulose-Decomposing Rates of Twelve Denton County, Texas Soils

Description: In this study twelve types of top soil were collected under aseptic conditions. The cellulose-decomposing rates of these were compared in order to determine the relative rates in the cellulose-decomposing potential of the microorganisms involved. Furthermore, this investigation is designed to acquire pertinent information on the rate at which natural cellulose materials are returned to available plant food.

The Sensitivity of Human Blood Plasma to the Coagulase Enzyme Secreted by Members of the Genus Micrococcus

Description: The problem in this investigation consisted of, first, the isolation from human sources and identification of thirteen cultures of typical micrococci to be used as test organisms; second, the acquisition of blood plasma from thirty different human beings; and third, the determination of the possibility of individual variation in sensitivity of blood plasma to the micrococci used as test organisms as revealed by the coagulase test.
