Organic acids: Microbes produce various organic acids while performing various activities and functions.

Wine and beer are produced without distillation whereas whisky, brandy and rum are produced by distillation of the fermented broth. Varieties of alcoholic drinks are produced, depending on the raw materials used for fermentation and the type of processing (with or without distillation). For this purpose, Saccharomyces cerevisiae, also called brewer’s yeast, is used for fermenting malted cereals and fruit juices, to produce ethanol.

Fermented Beverages: Microbes, especially yeasts, have been used since ancient times for the production of beverages like wine, brandy, beer, whisky or rum.

Streptomyces, a genus of bacteria, which belongs to actinomycetes, produces several antibiotics like streptomycin, chloramphenicol/chloromycetin, tetracycline, terramycin, and erythromycin.

Antibiotics have helped us to treat the deadliest diseases such as plague, whooping cough (Kali Khansi), Diphtheria, Leprosy, and a lot more. After Penicillin, many other antibiotics were also extracted from microbes. For this discovery, Fleming, Chain and Florey were awarded the Nobel Prize in \(1945\). This antibiotic was used to treat wounded American soldiers in World War II.

Its full potential as an antibiotic was later found by Ernest Chain and Howard Florey. The first antibiotic produced was Penicillin discovered from the fungus Penicillium notatum by Alexander Fleming. Antibiotics are considered one of the most significant discoveries of the 20th century and have greatly contributed to the welfare of human society. Antibiotics: Antibiotics are chemical substances, which are produced by some microbes to kill or inhibit the growth of other (disease-causing) microbes.Many fermented beverages, antibiotics and chemicals are synthesised for commercial purposes.

In Industries, microbes are cultured in very large vessels called fermentors. Microbes are also useful in industries to produce a number of products valuable to human beings. This process increases the nutritional value of milk by increasing vitamin \(\) during the process of fermentation.įig: Uses of Microbes in Household Products Microbes in Industrial Products Lactobacillus is a microorganism that is the major part of the group of lactic acid bacteria which grows in milk and converts it into curd. Microbes such as Lactobacillus and others commonly called lactic acid bacteria (LAB) are present in milk and convert it to curd. A common example is the production of curd or yoghurt from milk.You’ll be amazed to know that we use microbes or products derived from them in many of our daily activities. Let’s discuss these uses in further detail. Some of the contributions of microbes to human welfare are discussed below: It is possible to grow microbes in laboratories or at an industrial scale for research and production of various useful products. Various microorganisms can tolerate extreme conditions like high salinity (halophiles), deep inside temperature (thermophiles) and in highly acidic atmosphere (thermoacidophiles). Louis Pasteur is considered as the Father of Modern Microbiology. The branch of science which deals with the study of different aspects of microorganisms is known as microbiology. The most common types are bacteria, viruses and fungi. Microbes are tiny, unicellular (single-celled) living organisms that are invisible to the naked eye.
