I would like to approximately describe about my research. I had cultivated my yeast (Yarrowia lipolytica) in non sterile wastewater from palm oil mill industry and some contaminated microorganisms had been found in a significant numbers. In primary screening by plate count agar, the contaminated microorganisms were bacteria and fungi. In this part, there are about 20-30 samples. To complete this part, my advisor and research committee have suggested using PCR DGGE for detecting microbial community. In fact, there are many molecular techniques used for the work. Thus, if there are any other techniques that are suitable for my work, could you please suggest me? For expense and fee relating to research, I am willing to be responsible however there is not exceeding 2,500 Euro.
