1Introduction and some of the terms of microbial ecology Introduction and some of the terms of microbial ecology
2Microbial nutrition, terms of microbial nutrition, growth and growth factors Interactions of microorganisms: Commensalism, Sinergism, Antibiosis
3Factors affecting the growth and dispersal of microorganisms in nature: Physical factors (Temperature, Hydrostatic pressure, osmotic pressure, surface tension, visible radiation, Ultraviolet irradiation, ionising radiation)Parasitism: Isolation of bacteriophages
4Physical factors (Adsorbsion and viscosity), Chemical factors Microorganisms–human interactions Isolation of S.aureus from human skin: catalase, coagulase, Novabiocin susceptibility of the isolates Streptococcus isolation from throat using blood agar: α hemolysis, ß hemolysis, bacitracin susceptibility of group A - ß hemolytic streptococci
5Habitat types of Microorganisms: Terrestial and aquatic environments S. mutans (Mitis-Salivarus Agar) and C.albicans (ChromAgar Candida) isolation from saliva E.coli Isolation from faecal matter and carrying out the IMVIC tests of the isolates
6Atmospherical Environments Biological Environments Monitoring the biofilm formation in Candida albicans
7Dispersal of MicrorganismsSulphur cycle and Winogradsky column Enrichment and isolation of Beggiota Enrichment and isolation of Thiobacillus Enrichment and isolation of sulphate reducing bacteria Enrichment and isolation of Chromobacteria
8MidtermInteractions of microorganisms: Commensalimm, Sinergism, Antibiosis
9Microbial Interactions: Competition, Succession in an ecosystem Nitrogen cycle
10The role of Antimicrobial substances, toxins and organic inibitors in the formation of a community Extremophilic microorganisms: Isolation of thermophilic, halophilic and alcalophilic microorganisms. Monitoring the amylase, proteinase and lipase activities of thermophilic bacteria.
11The roles of simple organic toxins, antibiotics and bacteriosins. The role of other antibiotics Extremophilic microorganisms: Isolation of thermophilic, halophilic and alcalophilic microorganisms. Monitoring the amylase, proteinase and lipase activities of thermophilic bacteria.
