AI Article Synopsis
- Changes in lipid composition help micro-organisms adapt their membrane functions to environmental stressors.
- The study focused on Pseudomonas aeruginosa and its response to UV-C stress during both mid-exponential and stationary growth phases.
- Key findings included the identification of major phospholipid fractions and an increase in unsaturated fatty acids, indicating the organism's ability to recover effectively from UV-C damage.
Article Abstract
The changes in lipid composition enable the micro-organisms to maintain membrane functions in the face of environmental fluctuations. The relationship between membrane fatty acid composition and UV-C stress was determined for mid-exponential phase and stationary phase Pseudomonas aeruginosa. The total lipids were obtained by dichloromethane/methanol (3:1) and were quantified by GC. The TLC analysis of phospholipids showed the presence of three major fractions phosphatidylethanolamine, phosphatidylglycerol, and cardiolipin. Significant modifications, as manifested by an increase of UFA, were obtained. Interestingly, this microorganism showed a remarkable capacity for recovery from the stressful effects of UV-C.
