(abstract)

Anerobic digestors have the potential to become a major green energy source in a future sustainable society. To achieve this, effective operational parameters of the reactors must be established and maintained preferably by automation. In situ monitoring and control of anerobic digestor systems is currently a challenging matter based on inconsistent feedstuff composition and the complexity of the biological processes involved, so that reactor shutdowns associated with costly downtime are a common problem. Here we have developed a sensing device for the monitoring of volatile fatty acids, key intermediates during bioreactor operation, in the headspaces of anerobic reactors. The device is compact, contains a sensing element based on a self-assembled molecular layer in conjunction with a nanomechanical sensor, and can be used to monitor volatile fatty acid contents in bioreactors by estimating their relative contents in the reactor headspace in real time. A molecular nanoarchitectonic approach is used to synthesize a microporous polycrystalline sensing layer on a membrane-type surface stress sensor, a nanomechanical sensor. This device allows the close monitoring of volatile fatty acid concentrations in admixture towards cost-effective operation of bioreactors by reducing or eliminating reactor downtime. It represents a simple solution to the problem of real-time reactor monitoring making anerobic digestors a realistic alternative energy source.
