Abstract
An apparatus is described in which large numbers of algal cultures can be maintained under the following conditions: (1) Constant temperature within the range 5 to 70°C, four different temperatures being maintained simultaneously; (2) uniform illumination at intensities up to 20,000 metre‐candles; (3) continuous shaking at variable speed; and (4) aeration under aseptic conditions with mixtures of up to four different gases in any desired proportions.Among other features, thermoregulator heads, flow‐meters and heaters for sterile filters, of improved design are described.To illustrate the use of the apparatus, data showing the effects of light intensity and temperature on the growth of Monodus subterraneus are presented.
