Abstract
Certain embodiments of the invention involve methods and systems for preselecting, adapting, and preconditioning one or more species of photosynthetic organisms, such as algae, to specific environmental and/or operating conditions to which the photosynthetic organisms will subsequently be exposed during utilization in a photobioreactor apparatus of a gas treatment system. Also disclosed are new algal strains and cultures that can be produced by practicing the preselection, adaption, and preconditioning methods.
Claims23
A method comprising acts of:
- exposing a liquid medium comprising at least one species of photosynthetic organisms therein to a defined set of growth conditions, which are selected to simulate conditions to which the photosynthetic organisms will subsequently be exposed in a photobioreactor, to precondition the photosynthetic organisms to the defined set of growth conditions, the step of exposing being performed over a period sufficient for the photosynthetic organisms to undergo multiple generational natural selection and adaptation;
- harvesting photosynthetic organisms preconditioned in the exposing step;
- and
- inoculating a photobioreactor with at least a portion of the harvested photosynthetic organisms.
