MICROBIOLOGY LABORATORY
BACK

Microbiology analyses, isolation and enrichments of specific cultures for M.Sc. and Ph.D. research projects are carried out at the environmental microbiology laboratory.  The Laboratory also serves undergraduate environmental engineering students to teach general microbiology testes and analysis used in Environmental Engineering .

The general microbial test conducted in the laboratory are identification of bacteria, fungus, algae, yeast, and protozoa in drinking water, groundwater, and wastewater, the identification of flock forming and filamentous bacteria in the activated sludge systems, and the enumeration of all the microbial groups present in the sludge and compost. All the conventional and the enrichment toxicity assays related to bacteria, fish (based on toxicity dilution factor),  algae, and protozoa can be done. Autoclave, ovens, sterile planting apparatus with UV lamp, monocular and binocular research and student microscopes, membrane filtration equipment, refrigerator, centrifuge, magnetic stirrer with heater, vapor bathes, sterile planting apparatuses, special nutrient for microorganisms, anaerobic planting apparatuses, and pH meters present at the laboratory and available for both graduate and undergraduate students.

Several research projects about development of different pure aerobic and anaerobic bacteria cultures and enrichment have been performed at the lab. by the financial support of Government Planning Institution of  Turkey (DPT), Turkish Scientific Research Foundation (TUBİTAK) and  Dokuz Eylül University Research Foundation.

The routine analyses carried  out in microbiology laboratory are as follows:

* identification  and enumeration of  Total  and Fecal coliform bacteria

* enumeration of total bacteria, total aerobic bacteria, enumeration of spore forming and non- spore forming bacteria

*determination and enumeration of fungus and algae

*identification  and enumeration of

       *Streptococcus feacalis

     *sulfur oxidizing bacteria (Thiobacillus sp.)

     *sulphate reducing bacteria (Desulphovibrio sp.)

     *proteolytic bacteria

     *yeast.

     *iron bacteria

* determination of acid forming bacteria

* Actinomycetes identification

* determination of  Nitrite/Nitrate forming bacteria

* determination of the cellulolitic bacteria and protozoan

* Toxicity determination in  wastewaters (fish and bacteria toxicity)

* microbiological examination of activated sludge

* determination of the flock forming  and filamentous bacteria in activated sludge

* Escherichia coli  and Pseudomonas sp. determination

* microbiological examination and species determination of compost

* conventional algae and protozoa toxicity assays

*The enrichment bacteria toxicity assays
