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

Methods for Controlling Microbial Growth

https://openstax.org/details/books/microbiology/

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.

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.
