I thought I should introduce myself before the e-seminar
closes in a week (and hope that others will also do the same
In the context of the topic of this e-seminar, I did some
preliminary and investigative work in the 80s on the
degradation of diesel oil and diesel that may find itself
into the sewers. This work was done when I was at the Unit
for Bioengineering at the Dept of Bacteriology, Karolinska
The work was relevant to cities that drain surface runoffs
into rivers and for societies that flush everything through
their toilets and to sewage treatment plants. These rivers
and sewage treatment plants will be the sinks for any
spilled or disposed diesel oil.
I basically ran enrichment cultures under aerobic and
anaerobic conditions. I remember that under anaerobic
conditions and using the same dose (dosage: dont remember
what it was), my cultivation failed. An anaerobic mixed
culture could however be developed by stepwise increase in
the amount of added diesel (starting with small amounts). I
finally could reach the amount that killed the culture in
the first set of experiments and even higher.
Lab facilities were very poor at that time and so chemical
analysis to follow degaration of the residual amounts of
diesel were not done.
That was all I have done in the lab. I did however read a
lot of literature on this topic as well as the degradation
of pesticides in e.g. rice fields. I was particularly
attracted to the resilience of natural systems to
recover/degrade anything foreign to receives if sufficient
time is given to such natural soil/water ecosystems.

My business is water recycling
My interest in this subject stems from the fact that
pollutants from industry and byproducts produced by human
settlements, many of which are oil based, end up in our
waterharvesting and recycling systems. I am very interested
in anything or any process that can help break down and
utilise these (Waste) resources.

From: Behzad Shahmoradi
I am a student of IVth Sem.of M.Sc.in Environmental Science,
University of Mysore want to conduct my project work titled
as" Bioremediation of polluted soil in petrochemical sites".
Please if you have any methodology in this case, please
forward it to me.
Plants to coagulate oils

I was wondering Paul how we could adopt the findings of this
paper in creek bed systems but, if it may be useful in
cleaning oils if done.
However we could use plant extracts in coagulating the oils
in waste water as well.

I would like to know if from your aims you intend to based
your investigation on a laboratory based-exercise or a field
I should be able to provide some protocols.

Dear Dr Irfanullah,
I think we can use the compost of mushrooms to improve bad
soil, and I think the spent substrate would be useful in
making nursery for trees.
I do believe it could be useful in stimulating mycorrhzae
What do you think?
Thanks for the co-ordination of this seminar.
