Definition of microaerophilic in English:
microaerophilic
adjective ˌmʌɪkrəʊˌɛːrəˈfɪlɪk
Biology (of a microorganism) requiring little free oxygen, or oxygen at a lower partial pressure than that of atmospheric oxygen.
Example sentencesExamples
- When O2 is supplied to the cells under the microaerophilic conditions, the aerobic respiration will be stimulated.
- Most organisms are of bowel origin, with Escherichia coli, Klebsiella pneumoniae, bacteroides, enterococci, anaerobic streptococci, and microaerophilic streptococci being most common.
- The cultures were incubated at 37 deg C in the controlled microaerophilic atmosphere described earlier or three days.
- It can be seen from Fig.4, lower panel, that the yellow emission was relatively enhanced by the addition of cyanide under the microaerophilic conditions.
- After overnight incubation in selective media, recombinants were plated onto MM agar containing 20 g/ml kanamycin and maintained at 25°C in a sealed gas jar under microaerophilic conditions.

noun
Biology Detecting anaerobes and microaerophiles is difficult because these microorganisms must be incubated in a controlled gaseous environment that is either oxygen free or extremely oxygen deficient.
Example sentencesExamples
- Hence, they were likely to be strict anaerobes, or possibly microaerophiles, with a capacity to degrade sugars and/or amino acids, forming acetate as one of the end products.
- Early models assumed that all magnetotactic bacteria are microaerophiles and indigenous in sediments.
- In addition to being able to respire with oxygen, some microaerophiles may be capable of respiring anaerobically with electron acceptors other than oxygen.
- H. pylori is a microaerophile and thus requires oxygen concentrations that are below 21% partial pressure (normal atmospheric concentration).
