Modification of the Oligidic Medium for Axenic Culture of Aphelenchoides rutgersi.
Aphelenchoides rutgersi was axenically cultured in modified Soytone, yeast extract, lyophilized chick embryo extract medium (3% ST:2% YE:20% CEE-L, w/v:w/v:v/v). Earlier formulations used 10% CEE, v/v, before the manufacturer changed the preparation. After reestablishing A. rutgersi in medium that permitted continuous subcultivadon and reproduction, a second medium was tested that contained 0.5% sucrose and 0.5% Lipid Concentrate. The commercially available Lipid Concentrate made it possible to incorporate nonaqueous soluble chemicals into the medium. In addition, 0.1% Fast Green #3 was added to both media to visually demonstrate active ingestion of nutriment.
