Biosurfactant production by Pseudomonas aeruginosaGS3 from molasses

Patterns of long-chain faecal fatty acids were studied by gas–liquid chromatography in 55 newborn infants in a neonatal intensive care unit. Decreased fractions of fatty acid C16 : 1⁹ and increased fractions of C16 : 0 and C17 : 0 were associated with the occurrence of abdominal distension. Decreased fractions of C16 : 1⁹ and C18 : 2^9,1 were associated with diarrhoea. Flatulence was found in infants who had relatively smaller amounts of fatty acids C17 : 0D and C15 : 0 in their faecal samples. The differences in the patterns of faecal fatty acids are due to differences in bacterial flora. The results support the hypothesis that the initial intestinal colonization plays a role in the later gastrointestinal signs of newborn infants.
