Although using normal cleaning products can help reduce bacteria on household surfaces, disinfectants can kill them. Some examples of disinfectants that can kill bacteria on surfaces include: products that contain alcohol, such as ethanol and isopropyl alcohol. household bleach.... read more ›
Heat is one way to kill bacteria. This is why medical instruments are often sterilized in an autoclave. However, different species of bacteria are killed at different temperatures. Another way to kill bacteria is by exposing them to bactericidal chemicals such as peroxides or certain types of antibiotics.... read more ›
How do you remove bacteria from water? Bacteria can be removed from water through chlorine, UV disinfection, and ozonation. Chlorination is widely used by municipalities to remove bacteria from city water supplies. Many well owners also use chlorine to “shock” their wells and eliminate any bacteria present.... see more ›

- Distillation. Fill a pot halfway with water.
Other studies report that water pasteurized at 150°F/65°C for 20 minutes will kill or inactivate those organisms that can cause harm to humans. These include: Giardia, Cryptosporidium, Endameba, the eggs of worms, Vibrio cholera, Shigella, Salmonella bacteria, those that cause typhoid, the enterotoxogenic strains of E.... continue reading ›
There are several methods used in the water purification process, which include: (1) physical processes, such as filtration, sedimentation, or distillation; (2) biological processes, such as sand filters, active carbon; (3) chemical processes, such as flocculation, chlorination, the use of ultraviolet light.... view details ›
- HEAT - The easiest, effective way to control microbial growth is to use a FLAME.
- BOILING - Will not kill bacterial spores, so may not be sterile.
- AUTOCLAVE - Spores are killed with exposure to autoclave. ...
- OVEN - Oven use dry heat.
Many bacteria treatment systems involve the addition of a chemical to kill or inactivate, but bacteria can be removed physically by filtration or through the use of ultraviolet (UV) radiation.... see more ›
Methods of Bacterial Culture
Agar Plates: Scientists can grow the bacterial culture in a petri dish containing a thin layer of agar medium. The agar plates are inoculated with the desired bacteria strain and stored in an incubator overnight at an optimal temperature that is suited for the bacteria's growth.... read more ›
