The Nutrient Status of Algal Cells in Continuous Culture Droop

Do you know that oil derived from algae is an exciting renewable fuel possibility? – see Oilgae for more.

The Nutrient Status of Algal Cells in Continuous Culture Droop, MR Journal of the Marine Biological Association of the UK, VOL. 54, NO. 4, P. 825-855, 1974. 12 FIG., 9 TAB., 23 REF.

Growth of the alga monochrysis lutheri was studied under the steady-state conditions of a chemostat to show the relation between growth rate, rate of nutrient uptake, and the simultaneous internal and external concentrations of two nutrients (phosphorus and vitamin b12). The growth rate and internal concentrations of both limiting and excess nutrients were related by simple rectangular hyperbolas. Control followed a threshold rather than a multiplicative pattern, that is, nonlimiting nutrients had no control over the growth pattern. The limiting nutrient was that which showed the smallest cell quota: subsistence quota ratio. Two modes of growth were observed for monochrysis populations. ‘Slow adapted cells’ differed from ‘fast adapted cells’ in the values of the constants for the above ratio. Uptake of limiting and non-limiting nutrients was controlled by internal and external substrate concentrations, so there was a limit to luxury consumption of one nutrient when growth was limited by another nutrient. A mathematical model formulated for growth in a chemostat allowed prediction of external and internal substrate concentrations, uptake rates of the two nutrients, and biomass given only the input concentrations of the two nutrients and the dilution rate. This model should also be applicable to growth in batch culture. (buchanan-davidson–wisconsin).

algOS – Biodiesel from Algae Open Source

About Oilgae – Oilgae – Oil & Biodiesel from Algae has a focus on biodiesel production from algae while also discussing alternative energy in general. Algae present an exciting possibility as a feedstock for biodiesel, and when you realise that oil was originally formed from algae – among other related plants – you think “Hey! Why not oil again from algae!”
