THE CULTURE OF BRINE ALGAE

1. The conditions which the brine algae require for growth were found to be relatively simple. The high temperatures in the pond waters during the summer are well within the tolerance range of these organisms.

2. Simple nitrogenous substances and no organic supplements are required. No need for organic growth factors could be demonstrated under the conditions of cultivation used. Sea water, especially as it concentrates by evaporation, probably contains most of the required trace elements in sufficient quantity. It is possible that for mass cultivation of very dense algal suspensions, supplements of the micro-nutrients will be required.
