MICROBES IN HUMAN WELFARE

MICROBESMicrobe is a microscopic

organism, which may be a single cell or multicellular organism.

The study of microorganisms is called microbiology.

MICROBES CAUSE LARGE NO OF DISEASES IN HUMAN

BEINGS.

But Microbes useful in our daily life, Industrial

life etc.

1: MICROBES IN HOUSEHOLD PRODUCTS

2: MICROBES IN INDUSTRIAL PRODUCTS

3: MICROBES IN SEWAGE TREATMENT 4: MICROBES IN PRODUCTION OF BIOGAS

5: MICROBES IN BIO CONTROL AGENTS

6: MICROBES AS BIO FERTILIZER

MICROBES IN HOUSEHOLD PRODUCTS

1: A common example is curd from milk. Lactobacillus is that microbe which

convert the milk into curd. It is also known as lactic acid bacteria.

CONVERTING MILK TO CURD WHICH ALSO INPROVES ITS NUTRITONAL QUALITY BY INCREASINGVITAMINB12.

IN OUR STOMACH TOO, THE LAB PLAY VERY BENEFICIAL ROLE IN

CHEKING DISEASE CAUSING MICROBES.

USE OF LABBIOPRESERVATION:-

In milk, brined vegetables, many cereal products and

meats with added carbohydrate, the growth of lactic acid bacteria produces

a new food product.

SACCHAROMYCES CEREVISIAE

1: Used for making Dosa, Idli and chole bhature. It is due to the production of CO2.

Cheese is the oldest item in which microbes were used.

Different varieties of cheese are known by their characteristics texture, flavor and taste.

The specificity coming from MICROBES.

Propionibacteriumshermaani and Roquefort cheese

For making Swiss cheese. There is large holes in Swiss cheese due to larger amount of CO2.

Roquefort cheese are ripened by growing a specific fungi on them, which gives a particular flavor.

MICROBES IN INDUSTRAIL PRODUCTS

INDUSTRIAL FERMENTATION IS THE INTENTIONAL USE OF FERMENTATION BY MICROORGANISMS SUCH AS BACTERIA AND FUNGI TO MAKE PRODUCTS USEFUL TO HUMANS. FERMENTED PRODUCTS HAVE APPLICATIONS AS FOOD AS WELL AS IN GENERAL INDUSTRY.

Industrial fermentation

WHAT ARE FERMENTORS?Even in industry, microbes are used to synthesize a number of products valuable to human beings.

Production on an industrial scale, require growing microbes in very large vessel called fermentors.

FERMENTED BEVERAGESMicrobes especially yeast have been used from time immemorial for the production of beverages like wine, beer, whisky, brandy or rum

Same yeast saccharomyces cerevisiae used for making bread

and commonly called brewer’s yeast.

ANTIBIOTICSAnti means ‘against’

Bio means ‘life’.Antibiotics are the chemical substance, which are produced by some microbes and can kill or retard the growth of other microbes. Ex like penicillin.

After penicillin, other antibiotics were also purified

form other microbes.

Antibiotics have greatly improved our capacity to treat deadly disease such as plague, whooping cough(kali khansi) and leprosy(kusht rog). Which used to kill millions all over the globe. Today, we can’t imagine a world without antibiotics.

CHEMICALSMicrobes are also used for commercial and industrial production of certain chemicals like organic acids, alcohols and enzymes.1 :- Aspergillus niger(a fungus) produce citric

acid2:-Acetobacter aceti(a bacterium) produces

acetic acid.3:- yeast for the production of ethanol.4:- lactobacillus for the production of lactic

acid.

ENZYMESMicrobes are also used for the production of Enzymes.1:- Lipases are used in detergent formulations and are helpful in removing oily stains from the laundry.

ENZYMESHave you ever noticed the bottled fruit juices boughtfrom the market are clearer as compared to those made at home why?Proteases and Pectinases are the reason for above question.

ENZYMESStrepetokinase produced by strepetococcus and modified by genetic engineering is used as a ‘clot buster’ for removing clots from the blood vessels of patients who have undergone myocardial infection leading to heart attack.

BIOACTIVE MOLECULE

Trichoderma polysporum:- CyclosporinA, that is used as an immunosuppressive agent in organ-transplant patients.

BIOACTIVE MOLECULE

Monascus purpureus-: Statin is used for blood cholestrol lowering agents. It acts by competitively inhibiting the enzyme responsible for the synthesis of cholestrol.
