US Patent:

51320878, Jul 21, 1992

Filed:

Oct 16, 1989

Appl. No.:

7/421639

Inventors:

Kristen L. Manion - San Leandro CA
Stephen C. Wardlaw - Old Saybrook CT
Robert A. Levine - Guilford CT

International Classification:

G01N 1505

US Classification:

422 58

Abstract:

Blood constituents are separated by centrifugation in a transparent tube which contains a float for physically elongating certain of the constituents. The centrifuged sample in the tube is positioned on a layer measuring device with which red cell and buffy coat constituent band heights can be measured in ambient light. The buffy coat constituent measurements are made under optical magnification. The measuring device has a mathematically derived red cell layer nomogram printed thereon, and a separate scale for measuring buffy coat constituent bands. Conversion tables are provided for converting the measured buffy coat constituent band lengths into constituent cell counts. The measuring device includes tube-engaging portions for properly positioning the tube during the measurements, and the red cell scale automatically compensates for the presence of the float and densification of red cells needed for proper banding.

Abstract:

This invention relates to the use of microorganisms for the generation of ethanol from lignocellulosic waste materials. Yeast strains of the genus which have the capability to ferment cellulose, hexose sugars to ethanol are provided. Also provided are methods for converting cellulose, hexoses, or mixed hydrolysates of hexoses to ethanol by fermentation with strains. The invention also provides methods to isolate yeast strains which metabolize cellulose, pentoses, or hemicelluloses from waste materials.
