The use of a 7-10 day old stock culture will insure a sufficient amount of viable algal cells in the exponential growth phase. The . initial algal cell count in the stock culture was determined with the aid of a hemocytometer (370,000 cells/ml). Algal Culture Mediums Standard culture and test medium vas prepared as outlined in Attachment #l. This algal culture medium provided all " nutrients essential for algal growth and also served as the diluent for all algal operations including the preparation of stock solutions. The pH of this synthetic algal medium was adjusted to 7.5 prior to use in assays. Culture Flasks: Bach 250 ml erlenmeyer containing 50 ml of test solution . comprised a test flask. Culture flasks and all other glassware were specially prepared as described in Attachment #2. Autoclaved foam plugs were used as flask closures, allowing for free gas exchange.
