          ANAEROBIC CULTURE METHOD  Hello, doctor vanakam,  The topic of discussion for today is anaerobic culture methods as informed in the previous post on the healing of tissues  https://www.stencildent.com/2020/07/healing-of-tissue-repairprocess.html  if you haven't checked the previous post do check it out using this link without any further ado lets get started.  CONTENT :  1) INTRODUCTION  2)CLASSIFICATION OF ANAEROBE  3)METHODS TO ACHIEVE ANAEROBIOSIS 1) INTRODUCTION : Anaerobic bacteria have grown only in the absence of oxygen These conditions are called as anaerobiosis Anaerobic media are used for cultivation of anaerobic bacteria Types of anaerobes: Obligate, eg: Clostridium tetani, Aero-tolerant, eg: clostridium histolyticum Facultative  2) CLASSIFICATION OF ANEROBE:                                       ...
