Hello Priyanka, the first thing you do after deciding on a research topic or interest is to gather as much literature on the subject matter and associated ones as possible. You read them. You study them. You note your points and identify the gaps. Ask appropriate questions. You obviously have not done your literature review because I can assure you, information on this question alone is 10,000+. I personally used about 2,000+ (in 2008). Take some time to do a thorough literature search. You will find everything you need. Bring the complicated aspects here after you must have explored other options like your supervisors, allied professors, post-docs and doctorates.

Hello Priyanka

Just i have some idea about this filed so sharing, Fatty acids and PFA's can be the best source of substrate for bioflavours. If you go through the literature, you will find it more details. incase of any tough problem you can always come back.

Thank U Kuldip Sabale for your suggestion...

I found publication carbohydrate as raw materials, I will search for fatty acid now...

Thank You Neetesh Soni Sir, Fermentation process optimization paper is very helpful.

Dear Ms.Priyanka: You have asked a very wide question about microbial fermentation. The media optimisation usually depends on growth (Biomass) build up, pH regime required for growth and your primary/secondary metabolite production rate etc. First thing, you may have to look for suitable carbon source along with nitrogen, Phosphates, other minerals required to support biomass production with in short period of time, for which you need to have standard growth curve and compare the same when you change the raw materials (one at a time). After that it is your interpretation and effort to produce your metabolite/s...................????

Hello Priyanka,

I recommend you to test several food industry by-products abundantly available in your country. Some of them contain high level of sugars to provide good growth of microbe. Both submerged and solid-state fermentation of these materials are suitable. However, selection of an appropriate microorganism plays a decisive role to produce high yield of bioflavor.

Hi, Priyanka Roy

Have a look at my papers. As you are based in India where water stress is already exist, I suggest my new fermentation approach I called marine fermentation.

GOOD LUCK WITH YOUR RESEARCH

We have several papers with dark- and photo-fermentation of different raw materials or organic wastes by bacteria published during last years in international journals with high impact. We have tried to optimize fermentation efficiency by external factors such as substrate concentration, external pH, redox potential and others to obtain bacterial biomass and valuable fermentation end products such as hydrogen gas.

You can use many agro-residues such as from barley, wheat, banana etc. as submerged fermantation and also you can optimize experimental efficiency by external factors, as well as using Semiparametric "Errors in Variables" EIV Models

Thank you Kemal Guven Sir, your suggestion is very helpful.

You try Response surface methodology (RSM). It will give best results for multiple parameters. So many articles on RSM are available in on-line for wide range of fermentation process.
