glutaryl-7-aminocephalosporanic acid. The method including obtaining a cell preparation from a microorganism which produces D-amino acid oxidase, the preparation being a cell-free extract or a suspension of permeated cells; adding a D- alpha-amino acid to the preparation; after the adding step, heating the preparation at 50°-75°C for 5-60 minutes; and incubating cephalosporin C in the preparation. Also disclosed are a method of converting cephalosporin C to glutaryl-7-aminocephalosporanic acid in the absence of exogenous H202, and a method of screening for a D-amino acid oxidase-producing microorganism.

PLANT P R O P A G A T I O N SYSTEM
The invention provides a method for measuring the activity of cholesterol oxidase. First, a monolayer including sterol, a phospholipid and fluorescent dye labeled phospholipid is formed on a surface of a cholesterol oxidase aqueous solution. Then, it is observed whether sterol domain fade-out occurs in the monolayer. The activity of the cholesterol oxidase can be determined on the basis of both the period of time during which the sterol domain fade-out has occurred and a concentration of sterol in a cholesterol oxidase aqueous solution. This process can be applied to a method for estimating the toxicity of chemical compounds.

A plant propagation system and method are provided for promoting the growth of plant tissue into small plantlets. The plant propagation system includes sealed, semipermeable membrane vessels for completely enclosing plant material therein. The sealed vessels generally are translucent and permeable to gases and liquids while remaining impermeable to biological contaminates. Plant tissue originally extracted from a parent plant can be placed within the sealed vessels and grown heterotrophically. Once the plant material has developed the capability to photosynthesize, the sealed vessels can be transferred to a greenhouse environment for photoautotrophic growth. Once in a greenhouse environment, the sealed vessels are supported in trays and exposed to light, gases, water and a liquid nutrient solution for optimizing growth. A central controller can be included in order to automate the system for controlling the flow of fluids in and out of the vessel support trays while also monitoring system conditions. A disinfectant can also be circulated within the system for destroying biological contaminants in the tray and outside the sealed vessels for maintaining an aseptic environment.
