Study Notes
Microbes in Human Welfare
- Microbes are major components of biological systems, besides plants and animals
- Various kingdoms contain microbes, some exclusively microscopic
- Microbes exist in diverse environments, including soil, water, air, and inside living organisms
- They are present in extreme environments like geysers, deep soil, and highly acidic conditions
- Microbes include protozoa, bacteria, fungi, viruses, viroids, and prions (infectious proteins)
- Microbes can be grown on nutritive media to form visible colonies, useful for study
- Microbes play an important role in human welfare
- Examples of microbes are shown in Figures 8.1 and 8.2
Microbes in Household Products
- Microbes are used daily, e.g., for producing curd from milk
- Lactobacillus, and other lactic acid bacteria (LAB) convert milk to curd
- LAB produce acids coagulating milk proteins and improving nutrition, including vitamin B12
- Bacteria also ferment dough (e.g., dosa and idli), resulting in CO2 production
- Traditional beverages/foods are produced through fermentation (e.g., toddy, cheese, bread)
- Microbes are used in making cheese with different specific characteristics, flavours and tastes (e.g., Swiss, Roquefort cheese), varying from traditional to modern
- LAB play important roles in digestion in the stomach, supporting a healthy gut microbiome
- Specific types of bacteria are involved in specific fermentation processes
- Some microbes play an important role in the making of specific foods, like dosa, idli, and others.
Microbes in Industrial Products
- Microbes produce numerous valuable industrial products like antibiotics and beverages
- Bacteria like Streptococcus produce commercially important antibiotics (e.g., penicillin), derived via fermentation, with various types of processing
- Penicillin was discovered accidentally by Alexander Fleming, and was later researched by Chain and Florey to establish its role in medicine, for which they received the Nobel Prize
- Microbes produce organic acids (e.g., citric acid, acetic acid), enzymes, and other chemicals
- Yeasts produce alcohol in beverages (e.g., wine, beer, whisky)
- Enzymes like proteases and pectinases (produced by microbes) are used in industry for juice clarification, food processing, and other industrial applications
- Microbes produce certain chemicals, enzymes, and bioactive molecules like cyclosporin A, statins (used in pharmaceuticals)
- Microbes are used to make specific chemicals like organic acids, alcohols, and enzymes. Microbes like Saccharomyces cerevisiae are used for alcohol production in several beverages.
- Microbes are used in the production of several other industrial chemicals and enzymes, including enzymes used for digestion and food processing. Microbes are also used in the production of ethanol (alcohol) for various beverages.
Microbes in Sewage Treatment
- Sewage (waste water) contains organic matter and microbes
- Sewage treatment plants utilize microbes to treat sewage
- BOD (biochemical oxygen demand) is a measure of organic matter in water; microorganisms utilize oxygen in consumption, therefore reducing BOD
- Primary treatment physically removes solids (e.g., grit) from wastewater, separating solids from the water stream.
- Secondary treatment (biological treatment) allows microorganisms to utilize organic matter in sewage, reducing BOD further, with multiple stages and processes, such as aeration and settling
- Activated sludge pumped back into aeration tanks serves as inoculum, a crucial step for continuous operation
- Biogas (methane, CO2) produced by anaerobic digestion (e.g., in sludge digesters) is an inflammable energy source, used for cooking and lighting
- Sewage is treated in Sewage Treatment Plants (STPs); microorganisms are a vital part of this treatment process. Several steps are involved in sewage treatment, including physical removal of debris, biological degradation of organic matter by microorganisms, and settling of solid waste.
Microbes in Production of Biogas
- Biogas is a fuel produced through microbial anaerobic digestion of organic matter, typically in anaerobic conditions, to produce a useful energy source
- Methanogens produce methane as part of their metabolic process when they ferment a source of organic matter, typically using organic waste and slurry
- Biogas plants consist of concrete tanks (e.g., 10–15 feet deep) to hold the slurry of animal dung or other wastes
- The slurry is supplied to the tank and gas produced rises to the top of the mixture through a gas holder; biogas can be used for cooking and lighting
- Biogas plants are often built in rural areas. Biogas production can be used as a source of energy for rural areas. Different types of organisms, such as bacteria, are involved.
Microbes as Biocontrol Agents
- Biocontrol utilizes microbes to control plant diseases and pests rather than just chemical methods of pest/disease control, reducing harmful environmental impact
- Certain microorganisms inhibit the growth of other organisms with specific control agents or through their actions on susceptible plants
- Bacillus thuringiensis (Bt) is an example of a microbial biocontrol agent that kills the caterpillars of certain insects; these microbes can have specific control actions and can be engineered for this purpose
- The use of biocontrol means that less harmful substances are used against pests, resulting in less harm to the environment
- Ladybirds are examples of useful insects used to eat pests. Biological control methods focus on natural interactions
- Use of chemical pesticides and insecticides is reduced, promoting environmentally friendly agricultural practices.
- Bacillus thuringiensis is an example of a microbial biocontrol agent Other beneficial microbes and organisms also contribute to this process. Trichoderma species also control specific plant pathogens which causes plant diseases.
Microbes as Biofertilisers
- Biofertilizers improve the soil by their nitrogen fixing or phosphorus boosting capabilities
- Nitrogen-fixing bacteria (e.g., Rhizobium in nodules of leguminous plants) convert atmospheric nitrogen into a usable form for plants
- Fungi form mycorrhiza associations with plant roots, enhancing phosphorus absorption, facilitating nutrient uptake from the soil
- Cyanobacteria (blue-green algae) fix nitrogen, enriching soil, and increasing fertility, contributing to soil health
- Diverse microbes improve soil quality and contribute to overall fertility
- Microbes in the genus Glomus form mycorrhizae associations, which boost phosphorus absorption in plants
- Bacteria like Azospirillum and Azotobacter fix atmospheric nitrogen organically. Microbes play a role in the nitrogen cycle. Bacteria, fungi, and cyanobacteria are important sources of biofertilizers, utilized in various soil, agricultural, and environmental settings.
