Yes, definitely. It will store this as a reserve carbon source and use it when other readily metabolizable carbon source become scarce in the environment. It has to do so as it non-sporing and this is the only way it will survive.

Dear Sir;

I hope the following attached files will answer to a great extent your question. Regards

Aromatics in petroleum include the monoaromatic

hydrocarbons such as benzene, toluene, and ethylbenzene,

and o, m, and p-xylene isomers (BTEX) and other alkylsubstituted

benzene compounds (Cn-benzenes), and polycyclic

aromatic hydrocarbons (PAHs) (which include oil-characteristic

alkylated C0- to C4-naphthalene, phenanthrene, dibenzothiophene,

fluorene, and chrysene homologous series and other

United States Environmental Protection Agency (US EPA) priority

PAHs).

There are different type of PHA molecule so  i have send one paper which include different type of biopolymer 

You may want to consult the following:

Thanks a lot to  every one , your suggestion are really  useful

The reply by Professor Noda is very fitting; Professor Alexander Steinbuechel is an authority on Biopolymers synthesized by microbes and the reference of that publication of 1995 is an excellent source of information on PHA. I have worked on a short publication on PHV some time back..

Dear  Dr. Ahil;

I hope it is not too late. The following attached book is an extremely important one in the area you are working in. Regards

thanks a lot abdelkader, and  according to me there is no point in late  on sharing, the knowledge, infact, now I  am getting more enthusiastic  to discuss  about the  PHAs.Monomers it would b every nice , if we continue our discussion  in the analysis part also i.e GC MS, NMR etc

Dear Ahil;

it is a great honnor and privilege for me to take more knowledge from you and I am ready for any discussion within my modest background. Sincerly Regards

Ahil,

The answer is YES. P. putida can metabolize and degrade long chain hydrocarbons and fatty acids. During the beta-oxidation hydroxyl fatty acid are formed at various chain length and can be incorporated into a poly-hydroxy-alkanoate polymer. In most cases C8, C10 and C12 are the major constituents of such PHA, but it all depends on conditions especially on the affinity and selectivity of the synthase enzyme responsible for the polymerization.

Thank you so much sir
