@ MAHI because they can grow all over the media from surface to the bottom as they can utilize oxygen or conduct fermentation in its absence.

2.@MAHI Autoclave uses steam under pressure. The steam cannot penetrate through oil and wax. Thus, dry heat sterilization is preferred than autoclave .

calssification of bacteria are of 3 types: ●.on the basis of shap:1.spirilla 2.bacilli 3.cocci ●in the basis of gram stain : 1.gram -ve 2.gram +ve ●on the basis of oxygen demand: 1.aerobic 2.anaerobic.
Nadiya
detail se please
Nouman
paresention hai iseley
Nouman
jo bacteria hote hai pehle to woh 3 tarha se unka classification kiya jata hai .pehle y ki shape kya hai ....lakin shape hum tab hi define kar payenge jab hum unhe pehchanenge ki bacteria ko kaise jane ki woh kaise hote hai or unka classification kaise hota hai
Nadiya
to hum gram staining karte hai
Nadiya
gram staining ek aaisi technique hoti hai jise hun 2 large group m devide karte hai
Nadiya
or differenciate karte hai bacteria ko
Nadiya
based on thir diff. cell wall constituents
Nadiya
gram staining ko 2 procedure mai distinguish between kiya gaya hai
Nadiya
gram positive and gram negative
Nadiya
phir
Nouman
gram +ve and gram -ve groups by colouring these cells red or violet colour.
Nadiya
red jo cells hogi woh pink bhi ho sakti h because stains ki wajah se uski quantity ki wajah se
Nadiya
gram positive bact.stain violet due to presence a thick layer of a peptidoglycon in theri cell walls are stained with.. or gram -ve bact.stain red .which is attribute to a thinner peptidoglycan wall.
Nadiya
ab hum unhe identify karenge microscope mai
Nadiya
then fir hum identify karte karte hum shape dekhenge
Nadiya
gram positive cocci or rod shaped k honge .or garm negative cocci or rods or spirochaetes honge .......lakin inke colour ki wajah se hum pehchanenge ki red or pink aaya to gram negative .or agar violet aaya to positive
Nadiya
ok?
Nadiya
fir
Nouman
or bhi types k hote hai bacteria jaise sphirical "cocci",rod "bacilli",spiral"spirilla",comma shape k jo honge woh"vibrio",or corkscrew shape k jo honge woh "spirochaetes.
Nadiya
fir
Nouman
or oxygen k basis pr dekhenge agar apan to woh :aerobic jo o2 ki presence m honge or anaerobic jo honge woh without oxygen ki presence mai servive karenge .sabhi micro organisms banate h energy cellular respiration k through. lakin aerobic and anaerobic k basis pr bhi diffrenciate hote hai yeh .
