Since paraffin is very similar to diesel, there is no reason why becteria should not live in the interface between water and paraffin as they live in the interface between water and diesel. Infection is much less likely to happen with paraffin since the containers are not open to the outside air (which brings the moisture)

All petrochemicals are subject

But the 'bugs' are not the same exactly and rarely a problem.

The main bugs found are of course the Diesel bug because of Sulphur, moisture and other compounds that encourage them. There is another that you don't find so often because the heat of the engine etc. effectively reducs it - but thats the Lub-oil one ...... this is partuicularly devastating on slow speed ships engines - where it can strip the internal apint from the engine sump etc.

So normally the only bug you should be concerned about is the diesel one and good husbandry will keep this generally down to manageable levels. Of course if you do suspect you are getting in deep doo-doo's with it - dose it by all means with a bio ...... but I for one do not advocate regular overuse of them.

There are two, the most popular is Hormoconosis Resinae and that is the one we commonly see and ashamedly I cant remember the name of the other one as I havent seen it in three years and have forgotten....doh!

Nigel, Once again you have opened the memory taps.
Loaded a mix of Oils in Grangemouth, took down to Falklands and the MOD declared the Helo fuel was bugged (can't remember what exactly the Chinooks were using) Nobody eles down there wanted the Navy Grade Furance Oil either (which in fact was so light it was just like Dirty Diesel Oil and caused also sorts of problems in our boilers, purifiers and the B&W) so we took it all back to Campbletown and stuffed the lot in the hillside. Agree with the Lube Oil bugs, they were really nasty little devils who has to be seen off by emptying the sump and cooking the lot to kill em off. I also don't subscribe to routinely dosing - seems to run risk of resistant breeding rather like the current Antibiotics resistant strains

Re: All petrochemicals are subject

two or more bugs affect kerosene based fuels cladisporium resinae , aspergillus niger and there are many others.

As they mostly breed form spores that can be airborne they enter tanks through vents and fillers etc. live in the water and feed on the carbon in the fuel. Heavily infected tanks of kerosene can have thick mats of the bugs floating on the interface. House keeping and dosing with biocide or other remedies of choice will keep them at bay.
