Types of microorganisms
Bacteria
Fungi
Viruses
Protozoa
Bacteria
• Both Autotrophic and Heterotrophic nutrition• Reproduction by binary fission• Dysentery (痢疾 ), Cholera (霍亂 ), Diphtheria (白喉 ) are cause by bacteria
Fungi
• Nutrition: secrete enzyme to break down complex nutrients into simpler forms they can absorb.
• Reproduction: Forming reproductive spores that are carried on wind or rain.
• Diseases caused by fungi: Ringworm (癬 ), Athlete’s foot (香港腳 ), Skin infection(皮膚病 )
Viruses
• Diseases caused by viruses: Measles(痳疹 ), Mumps(腮腺炎 ), Influenza(流行性感冒 )
Protozoa
• They can feed on body tissues and produce effect. For example: Malaria (瘧疾 ), Amoebic dysentery (亞米巴疾痢 ).
Useful of microorganism
A. Putrefaction B. NitrificationC. Nitrogen FixationD. Digestion of celluloseE. As a source of antibioticsF. Sewage treatmentG. Production of antibiotic by PeniclliumH. Bread ProductionI. Wine Production
Bread Production
Glucose + Yeast → Carbon dioxide + alcohol + energy
Wine Production
Sugary food + Yeast→ Fermentation→ Filtering→Beer
