List two ways to inhibit microbial growth
Web26 mrt. 2016 · Disinfection is the removal of growing microbial cells from a surface. When that surface is skin, the disinfecting agent is milder and is called an antiseptic. Another distinction to make is whether a chemical is bacteriostatic (which stops the growth of bacteria but doesn’t kill it) or bacteriocidal (which does kill bacteria). Physical methods WebMany work by inhibiting bacterial cell wall synthesis; These agents are generally referred to as β-lactam antibiotics. Antibiotics, such as the aminoglycosides, chloramphenicol, erythromycin, and clindamycin, inhibit protein synthesis in bacteria. Antibiotics such as polymyxin B and polymyxin E (colistin) bind to phospholipi Continue Reading 1
