Psychrophilic bacteria grow best at which of the following temperatures?
Ans. a (< 20degC) (Ref. Ananthanarayan Microbiology 7th/pg. 22)On the basis of temperature relationship, microorganisms are broadly divided into three groups:Phychrophiles grow optimally at0-5degCMesophiles at20~45degCThermophiles> 55degCMany yeasts and molds and, certain bacteria grow well in acidic media (pH 5.0 or lower) while most bacteria require a pH near neutrality (6.5-8.0) for optimal growth.
