Scientists began using chemicals to control microbial growth in the early 1800s. Some methods of chemical control include: 
- antiseptics
- disinfectants
- sanitization
- heavy metals

Using Chemicals to Control Microbial Growth

We can use physical methods of microbial control to preserve our food by manipulating the physical environment to inhibit or prevent microbial growth.
Common control methods include:
- moisture control
- radiation
- filtration
- temperature control

Many of these methods kill cells by disrupting membranes, changing their permeability, or denaturing proteins.

Physical Ways to Control Microbial Growth

Methods for controlling microbial growth include
- temperature control
- moisture control
- pH control
- chemical control

In order to maintain a healthy environment, we needed to develop ways to control microbial growth and reduce the microbial count to safe levels for public health. "Safe levels" depends on the type of environment you are in. A medical setting will require much lower microbial counts than inside our homes, and therefore require higher levels of decontamination

Microbiology covers the scope and sequence requirements for a single-semester microbiology course for non-majors. The book presents the core concepts of microbiology with a focus on applications for careers in allied health. The pedagogical features of the text make the material interesting and accessible while maintaining the career-application focus and scientific rigor inherent in the subject matter. Microbiology’s art program enhances students’ understanding of concepts through clear and effective illustrations, diagrams, and photographs.

Microbiology is produced through a collaborative publishing agreement between OpenStax and the American Society for Microbiology Press. The book aligns with the curriculum guidelines of the American Society for Microbiology.

There anre many ways to control microbial growth. The methods that are considered safe for skin include:
- antiseptics
- degerming


Types of Microbial Control for Living Tissue

Fomites are inanimate surfaces that can harbor microbes. To control microbial growth on fomites, we can use the following
- -cidal agents
- sterilization
- disinfection
- sanitization
- -static agents

Types of Microbial Control for Fomites.

Methods for Controlling Microbial Growth

static treatments do not actually kill infectious agents, they are often less toxic to humans and other animals, and may also better preserve the integrity of the item treated. Such treatments are typically sufficient to keep the microbial population of an item in check.

-Static

-cide (or -cidal). The prefix indicates the type of microbe or infectious agent killed by the treatment method: bactericides kill bacteria, viricides kill or inactivate viruses, and fungicides kill fungi.
