Projects
System biology in Pseudomonas
In this project, the production of low molecular organic
compounds by bacteria is researched. Therefore
metabolic networks and genes are examined. Due to a
confidentiality obligation, no further information of this
project could be shared.

Biodegradation of benzoate under hypersaline
conditions
Common bacteria normally used in the degradation
of natural and xenobiotic compounds tolerate sodium
chloride concentrations of up to 3.5 w%. This concentration
is similar to saline concentrations in maritime
habitates. Habitates with saline concentrations beyond
3.5 w% like salterns, industrial solar salt refineries,
brines out of the olive oil production or spezial industrial
waste waters can only be populated by specialised
bacteria and archaea. In most cases industrial waste
waters as well as waste waters of the olive oil production
include high COD freights. The biodegradability of
benzoate as main compound in these industrial waste
waters under technical aspects is the core aspect of
this third-party funded project.
In the Technical Instruction on Air Quality of the year
2002 „TA-Luft 2002“ a limit value of 20 mg C/m³ is
defined for the treated air of a hazardous waste recycling
plant. However, the limit value during design and
construction of this plant was 100 mg C/m³. To fulfill
the new limit values the existing system consisting of
preconditioning and bioscrubber units was modernised
and complemented in cooperation with the partner of
the project. In analytical campaigns on-site as well as
in semi-technical scale in the rooms of the Institute
the total waste air compounds were identified and carbon
freight, related compound concentrations as well
as specific degradation rates in both plants were measured.
Since the summer of the year 2008 the industrial
scale plant is capable to fulfill the limit values of
the TA-Luft 2002.
In a second phase of the project proceeding up to now
the feasibility of additional waste water treatment is
evaluated.

Optimisation of an existing industrial scale biological
waste air treatment system in a hazardous
waste recycling company to fullfill limit values of
the TA-Luft 2002
Industrial plant for combined waste air and waste
water treatment in a hazardous waste recycling company.
The waste air (inlet on the right side) passes
through an activated carbon filter (top right side) and
two serial connected bioscrubbers afterwards (top left
side). In three tanks the circulation liquid (bottom left
side) and the aqueous waste fractions (bottom right)
are stored.
