A sensor for detecting microorganisms in air, water, or deposited on surfaces. The sensor includes a source of light, a waveguide receptive to the source of light, a fluorochrome coating on the waveguide, and a detector which detects the Stokes shift of light passing through the waveguide in response to microorganisms fluorescing as they come into contact with the fluorochrome coating on the waveguide.

Sensor for detecting microorganisms

Wood is impregnated with a solution of tannic acid followed by impregnation with a solution of a metal in the form of a salt. The metal selected is one that will complex with both the impregnated tannic acid and the wood.

Protecting wood from wood degrading organisms

A magnetic separation method for recovering single cell protein from single cell organisms including dispersing magnetic seed in a fluid medium containing single cell organisms, to allow the attachment of the seed to the single cell organisms in the mixture to occur; submitting the resulting mixture to a magnetic separator to attract and hold by magnetic forces the seed and attached single cell organisms to concentrate the single cell organisms in the magnetic separator; lysing the entrapped single cell organisms to break the cell walls of the single cell organisms and release protein from the single cell organisms into the fluid medium; and recovering the released protein by discharging the fluid medium from the magnetic separator while the seed and remaining portions of the cells attached to the magnetic seed are held by the magnetic forces.
