Lecture´s Description

Principles of Microbial Control
The prime objective of this lecture is to elucidate the Control of Microorganisms in Environment. Section one mainly focuses on the Principles of Microbial Control. In the beginning, the definition of Antimicrobial Agent has been put forward. Moreover, Control of Microbial Growth and a few Terminology have been delineated. These include Disinfection, Sterilization, Antisepsis and Chemotherapy. Following this, these terms have been distinctly described. Firstly, Disinfection and Sanitization have been brought into consideration. Conclusively, the educator has talked about the Antisepsis and Chemotherapy.


Pattern of Microbial Death
The key focus of section two is on the Pattern of Microbial Death. At the start, the educator has conversed about the Exponential Death of Microbial Agents. Subsequently, Decimal Reduction Time and Effectiveness of Lethal Agent has been reported. In the end, Viable but Nonculturable Cells have been communicated about.


Mechanical Control Methods
Section three accommodates Mechanical Control Methods. The educator started off by mentioning about the process of Filtration. Amongst the techniques employed for filtration, Depth Filters and Membrane Filters have extensively been explicated. Next in line, Air Filtration has been narrated. Ultimately, HEPA Filters have been shed light on.  


Physical Control Methods
Section four accentuates the Physical Control Methods. First and foremost, Moist Heat has been debated over. Furthermore, Steam Sterilization and Pasteurization has been deliberated. Succeeding this, Tyndallization besides Dry Heat Sterilization has been brought into dialogue. In the end, the educator has concluded by alluding to the Radiations, comprehensively.


Chemical Control Methods
The key point of emphasis of section five are the Chemical Control Methods. Initially, Disinfectants and Antiseptics have been expounded. Additionally, Ideal Disinfectants alongside Ideal Antiseptics has been reflected upon. Besides this, Phenolics and Alcohols have been spoken about. Amongst, Halogens, Iodine and Chlorine has been brought under contemplation. Later on, the educator has referred to the Heavy Metals in conjunction with the Quaternary Ammonium Compounds and Aldehydes. Proceeding on, Sterilizing Gases have been conferred. Towards the end, the educator has stated about the Ethylene Oxide (EtO) and Sterilizing Gases.
