Lactobacillus, commonly called Lactic Acid Bacteria grow in milk and convert into curd
The puffed up appearance of the dough is due to the production of CO2 gas during fermentation by bacteria
dough is fermented using Bakers yeast, Saccharomyces cervisiae
Toddy is a traditional drink of some parts of Southern India. It is made by fermenting sap from palm trees
Cheese formed by the partial degradation of milk by different microorganisms
Swiss cheese with large holes is produced by Propionibacterium shermanii , the holes are produced to to large production of CO2
Roquefort cheese are ripened by growing a specific fungi, Penicillium roqueforti on it, which gives a particular flavor
A variety of microbes are used to synthesise a number of products valuable to human beings in industries.
Microbes especially yeasts have been used from time immemorial for the production of beverages like wine, beer, whiskey, brandy and rum — Saccharomyces cerevisiae is a yeast that is used in the production of bread and beer
Sewage refers to the municipal wastewater generated everyday in cities and towns. Human excreta is the major component of it.
before disposal sewage has to be treated in Sewage Treatment Plants in order to make it less polluting
Primary treatment also known as physical treatment because it basically involves the physical removal of small and large, floating and suspended solids from sewage through filteration and sedimentation
In primary treatment the supernatant forms the effluent
Secondary treatment is also known as biological treatment because it involves the use of microbes or microbiota for the treatment of sewage
BOD - Biochemical Oxygen Demand
The energy derived from biofuels is called bioenergy
Streptococcus thermophilus and Lactobacillus bulgaricus are used to make yogurt
Swiss cheese- Propionibacterium shermanii
Roquefort cheese - Penicillium roqueforti
Camembert cheese- Penicillium camemberti
Brewer‘s yeast- Saccharomyces cerevisiae
bakers yeast- Saccharomyces cerevisiae
Penicillin was the first antibiotic to be discovered and it was a chance discovery
whooping cough - kali khansi
leprosy - kusht rog
doptheria - gal ghotu
characteristics of a good antibiotic - harmless to host with no side effects, quick action, ability to destroy pathogen, harmless to normal microflora of alimentary canal and effective against all strains of pathogen
citrus acid is produced through the fermentation carried out by Aspergillus niger
Candida lipolytica provided its nutrient medium is deficient in iron and manganese
acetic acid is comercially produced from fermented alcohol with the help of acetic acid bacteria
lactic acid is commercially produced from fermentable carbohydrates such as corn and potato starch, molasses and whey by using Lactobacillus Bulgarians and L. delbruekii
butyric acid is produced during fermentation activity of bacterium Clostridium acetobutylicum
lipases obtained from Candida lipolytica and Geotrichum candidly are used in detergent formulations for removing oily stains from the laundry
Cyclosporin-A is used as an immunosuppressive agent in organ transplantation and is produced by Trichoderma polysprout
statin is produced by Monascus purpureus - used as blood cholestrol lowering agent by acting as a competitive inhibitor of enzyme for cholesterol
Primary treatment removes floating and suspended solids from sewage through filtration and sedimentation
the sedimented part is called primary sludge and supernatent is called effluent
The primary sludge traps a lot of microbes and debris, so it is subjected to composting land
The effluent is then taken for secondary treatment
secondary treatment is purely a biological treatment involving microbial activity
all microbes from flocs which are masses of bacteria held together by slime and fungal filaments to form mesh-like structures
the settled material is called activated sludge - the effluent passed through as sedimentation tank where microbial flocs are allowed to settle down
