They are found everywhere on earth ranging from soil, air water and some inhabitable places.<\/p>\n<p>Bacteria and fungi can be grown on nutritive media to form colonies, which can be seen by necked eyes and very useful in study of microorganisms.<\/p>\n<p>Microbes cause many diseases in human beings, plants and animals. Several microorganisms are useful to man in diverse ways.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Microbes_in_household_products\"><\/span><strong>Microbes in household products<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><strong>a.<\/strong> Microorganisms like Lactobacillus and other commonly called lactic acid bacteria (LAB) grow in milk and convert it to curd. The LAB produces acids that coagulate and partially digest the milk proteins. It also improves its nutritional quality by increasing vitamin B12.\u00a0 In our stomach too, the LAB play very beneficial role in checking disease-causing microbes.<\/p>\n<p><strong>b.<\/strong> The dough is used for making foods such as dosa and idli is fermented by bacteria. The puffed-up appearance of dough is due to the production of CO2 gas. The dough used for making bread is fermented using baker\u2019s yeast (Saccharomyces cervisiae).<\/p>\n<p><strong>c.<\/strong>\u00a0Cheese, is one of the oldest food items in which microbes were used. The large holes in \u2018Swiss cheese\u2019 are due to production of a large amount of CO2 by a bacterium named\u00a0Propionibacterium sharmanii. The \u2018Roquefort cheese\u2019 is ripened by growing a specific fungus on them for a particular flavour.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Microbes_in_industrial_production\"><\/span><strong>Microbes in industrial production<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>A number of products like beverages and antibiotics involve uses of microbes. Production on large scale requires growing microbes in very large vessels called fermenters.<\/p>\n<p><strong>a. <\/strong>Fermented Beverages- Saccharomyces cerevisiae used for bread-making and commonly called brewer\u2019s yeast, is used for fermenting malted cereals and fruit juices, to produce\u00a0beverages like wine, bear, whisky and rum.. Wine and bear are produced without distillation whereas whisky, brandy and rum are produced by distillation of the fermented broth.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone\" src=\"https:\/\/media-mycbseguide.s3.amazonaws.com\/images\/static\/revise\/12\/biology\/12_bio_ch10_01.jpg\" alt=\"Microbes in Human Welfare class 12 Notes Biology\" width=\"281\" height=\"218\" \/><\/p>\n<p><strong>b. <\/strong>Antibiotics- they are chemical substances produced by some microbes and can kill or retard the growth of other microbes.

Grit (soil and small pebbles) are removed by sedimentation.<\/p>\n<p>Secondary treatment or biological treatment involves passing of primary effluents in large aeration tank to help the growth of aerobic microbes into flocs (masses of bacteria associated with fungal filaments to form mesh like structures).\u00a0These microbes increase the consumption of organic wastes and decrease the BOD (biological oxygen demand)of the effluents.<\/p>\n<p>BOD is the amount of oxygen that would be consumed if all the organic matter in one litre of water were oxidised by bacteria. It measures the amount of organic matter present in the water. Greater the BOD of water more it is polluted.<\/p>\n<ul>\n<li>Once the BOD of sewage or waste water is reduced, the effluent is then passed into a settling tank where the bacterial \u2018flocs\u2019 are allowed to sediment. This sediment is called activated sludge.<\/li>\n<\/ul>\n<p>Sludge is passed into large tanks called anaerobic sludge digesters in which anaerobic bacteria digest the bacteria and fungi in the sludge and produce mixture of gas called biogas, which is a mixture of methane, hydrogen sulphide and carbon dioxide.<\/p>\n<p>The effluents from the secondary treatment plant are released into water bodies.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Microbes_in_Production_of_Biogas\"><\/span><strong>Microbes in Production of Biogas<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Biogas is a mixture of gases produced by the microbial activity that can be used as fuel. Certain bacteria that grows anaerobically on cellulosic material produce large amount of methane along with CO2and H2.

The chemical used as pesticides and insecticides are harmful to human beings and animals.<\/p>\n<p>Biological control of pests and disease is a method of controlling pest on natural prediction rather than chemicals. The organic farmer creates a system where the pests are not eradicated but kept at manageable level by complex system of check and balance within the living and vibrant ecosystem. For example, the Ladybird and Dragonflies are used to get rid of aphids and mosquitoes respectively. On brassicas and fruit tree, to control butterfly caterpillars bacteria Bacillus thuringiensis is used.<\/p>\n<p>Biological control developed for use in the treatment of plant disease is the fungus Trichoderma. Trichoderma are free-living fungi that are very common in the root systems that control several plant pathogens.<\/p>\n<ul>\n<li>Baculoviruses are pathogens that attack insects and other arthropods. The majority of baculoviruses used as biological control agents are in the genus Nucleopolyhedrovirus. These viruses are excellent candidates for species-specific, narrow spectrum insecticidal applications.<\/li>\n<\/ul>\n<h3><span class=\"ez-toc-section\" id=\"Microbes_as_Bio_fertilisers\"><\/span><strong>Microbes as Bio fertilisers<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Bio fertilisers are organisms that enrich the nutrient quality of the soil. The main sources includes bacteria, fungi and cyanobacteria.<\/p>\n<p>The root nodule formed by Rhizobium bacteria on root of leguminous plants increase the nitrogen level of soil, necessary for various metabolic processes. Azotobacter and Azospirillum are free living bacteria that live in soil and fix atmospheric nitrogen into organic forms.<\/p>\n<p>Symbiotic association of fungi with angiosperm plants (mycorrhiza) also increase the fertility of soil. Glomus form mycorrhiza that absorbs phosphorus from the soil and passes it to the plant. These microbes also provide benefits like resistance to root-borne pathogens, tolerance to salinity and drought.<\/p>\n<p>Cyanobacteria (Nostoc, Anabaena), an autotrophic microbes found in aquatic and terrestrial environment fix atmospheric nitrogen. In paddy field this acts as important bio-fertiliser. Blue green algae also add organic matter to the soil and increase its fertility.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"CBSE_Class_12_Revision_Notes_and_Key_Points\"><\/span><strong>CBSE Class 12 Revision Notes and Key Points<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Microbes in Human Welfare class 12 Notes Biology.
