Hi Everyone
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 Inst, Stockholm.
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.

-----forwarded message----- From: Behzad Shahmoradi
Dear Participants
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.
Yours faithfully Behzad Shahmoradi
++++++++++++++ Plants to coagulate oils Submitted by Kenneth-Yongabi... on Sat, 27/05/2006 - 17:05. ++++++++++++++
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 trial.
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 fungi.
What do you think?
Thanks for the co-ordination of this seminar. Kenneth
