Sterility can be achieved with filtration as filtration will allow the positive bacteria to sift through, while the negative harmful bacteria will be pulled out and separated from the organism as it once was.
Most often, the media used for animal tissue culture has to be filtered before growing cells in them. Media contains components like serum and other growth factor proteins. Therefore, the media cannot be sterilized through heat. Sterile filtration is a widely used method of obtaining sterile media
which media or both use for blood culture
1.) Autoclaving 2.) Dry heat sterilization 3.)bacteriological filter ** UV rays can be used to sterilize but they kill the organisms on the slide...so this practice is not used often only on select organisms that can survivie UV rays
Solid media is used for the isolation of bacteria as pure culture. 'Agar' is most commonly used to prepare solid media.
Anaerobic media, which does not contain oxygen, would not be used to culture aerobes. Aerobes require oxygen for growth, so an anaerobic environment would not support their growth.

Culture medium is a gel or liquid that aids in the growth of cells and microorganisms. The type of culture media that is used can vary.

Anaerobic media, which does not contain oxygen, would not be used to culture aerobes. Aerobes require oxygen for growth, so an anaerobic environment would not support their growth.
Autoclaving is used to kill all micro-organisms that are in the culture. Autoclaving is usually carried out at 121 deg C with steam under 2 atmospheres of pressure. A clean culture free of all micro-organisms is essential as you only want the organism of intrest to grow.

Yes, differential media is a type of culture media used to distinguish between different types of microorganisms based on their biochemical characteristics. It contains specific nutrients or indicators that allow for differentiation of microbial species or strains.
Some control methods that can sterilize heat sensitive materials without breaking them down include ethylene oxide (ETO) gas sterilization, hydrogen peroxide gas plasma sterilization, and liquid chemical sterilants like peracetic acid. These methods can effectively sterilize materials without exposing them to high heat that could cause damage.
