| Summary: | The present study aimed to provide an insight of C. jejuni ATCC 33560 phenotype profiles (carbon
sources and sensitivity to osmolytes and pH) using Phenotypic MicroArray (PM) system in response to optimal
and suboptimal temperature. C. jejuni ATCC 33560 showed utilization carbon sources from amino acids and
carboxylates but not from sugars. C. jejuni ATCC 33560 is sensitive to NaCl at 2% and above but showed
survival in a wide range of food preservatives (sodium lactate, sodium phosphate, sodium benzoate, ammonium
sulphate and sodium nitrate). When incubated at suboptimal temperature, no phenotype loss was observed in
carbon source plates. Phenotype loss of C. jejuni ATCC 33560 was observed in sodium chloride (1%), sodium
sulphate (2-3%), sodium formate (1%), sodium lactate (7-12%), sodium phosphate pH7 (100mM and 200mM),
ammonium sulphate pH8 (50mM), sodium nitrate (60mM, 80mM and 100mM), sodium nitrite (10mM), and
growth in pH5. The phenotypic profile from present study will provide a better insight related to survival of C.
