"From systems biology to fuel — Chlamydomonas
reinhardtii as a model for a systems biology approach
to improve biohydrogen production"
With economic wealth the need for energy is rising. Hence we are facing two
problems: to satisfy the increasing energy demand and concomitantly deliver
emission-free energy to avoid global warming.
The process of photosynthesis offers a natural and highly efficient method to produce
emission-neutral biofuels. However, using higher plants for such purposes causes
several problems which are difficult to overcome and includes competition with food
producing agriculture in terms of arable land, the need for fresh water, low process
efficiency and the application of energy-intensive fertilizer in order to enhance
growth performance.
Photosynthetic microorganisms and, in particular, microalgae offer an alternative
approach. In this case production sites in photo-bioreactors can be located on cheap,
rural land and the organisms can be cultured in sea water rather than fresh water.
However microorganisms are not naturally adapted as efficient producers of biofuels.
Due to the complex regulatory network and mutual interaction of physiological
processes and organelles, identifying the optimal production strategy is impossible
without a greater understanding of the complex interplay of all cellular processes.
Systems biology has emerged recently as a discipline to gain an understanding of
these networks and their translation into a mathematical in silico model. An in silico
model allows simulating optimization steps and, therefore, provides a useful method
to identify targets for directed genetic/physiological modification to optimize the
system for a biotechnological approach.
