Procedure

Starting with 100 mL of Stage IV singulation medium lacking ABA, 1.5 g of the algin composition PROTONAL LF20/60® sodium alginate product was added and stirred several hours without heating until dissolved. PROTONAL LF20/60® is a registered trademark of and the product is available from Proton, Inc., North Hampton, N. H. To this was added 1.0 g of activated charcoal to give a 1.0% (or 10 g/L w/v) suspension. This was autoclaved to ensure sterility. A 0.1M solution (23.6 g/L) of calcium nitrate tetrahydrate was prepared and autoclaved separately. The alginate suspension of charcoal was added dropwise to the calcium nitrate solution with gentle stirring. Small balls of insolubilized charcoal-containing alginate about 2-3 mm in diameter were formed. These were thoroughly rinsed with sterile water and stored in a closed flask under refrigeration. Fifty of the charcoal balls added to 50 mL of culture medium are equivalent to 0.1% w/v activated charcoal.
