Environmental Microbiology Basics
- "Environment" coined by Thomas Carlyle in 1828, from French "Environ" meaning surroundings.
- Environmental studies integrate physical, biological, and social sciences.
Microbiology
- Term "Microbiology" attributed to Louis Pasteur, defining the study of microscopic organisms.
- Antoni van Leeuwenhoek recognized as the "Father of Microbiology" for observing microorganisms.
- Microbial diversity includes bacteria, fungi, viruses, and protozoa.
Microbes
- First used by Sedillot in 1878, referring to microscopic organisms such as algae, bacteria, fungi, and viruses.
- Microorganisms have existed for approximately 4000 million years, with significant contributions from historical scientists in their identification.
Useful Bacteria
- Beneficial bacteria include Lactobacillus (yogurt production), Streptococcus, and other species that aid digestion and immunity.
- Soil bacteria produce antibiotics essential for treating infections.
Harmful Bacteria
- Pathogenic bacteria can cause diseases like pneumonia, cholera, tuberculosis, and typhoid.
Fungi
- Eukaryotic organisms, including yeasts, molds, and mushrooms, classified under kingdom Fungi.
- Characterized by a cell wall made of chitin and a heterotrophic lifestyle.
- Fungi play crucial roles in decomposition and nutrient cycling and contribute to antibiotic production (e.g., penicillin).
Salient Features of Fungi
- Fungi typically exhibit filamentous structures, with hyphae forming a woven network known as mycelium.
- Nuclear structures possess distinct chromatin threads and membranes.
Viruses
- Term "Virus" introduced by Martinus Willem Beijerinck in 1897; different from living organisms.
- Composed of genetic material and protein, viruses replicate only within host cells.
- Classified as obligate intracellular parasites.
Characteristics of Viruses
- Exhibit both living and non-living features: contain genetic material, but lack metabolic activity outside host cells.
- Ability to cause diseases and mutational change.
Protists
- Simple, eukaryotic, unicellular organisms; classified as autotrophic or heterotrophic.
- Includes plant-like (e.g., diatoms), animal-like (e.g., amoeba), and fungus-like (e.g., slime molds).
- Essential for recycling nutrients and providing oxygen.
Features of Protists
- Mostly aquatic or found in moist environments; some can grow to significant sizes (e.g., Giant Kelp).
- Structure includes a nucleus and membrane-bound organelles, varying nutritional needs based on autotrophic or heterotrophic characteristics.
