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
