Staphylococcus aureus osmoregulation: roles for choline, glycine betaine, proline, and taurine.
Choline, glycine betaine, and L-proline enhanced the growth of Staphylococcus aureus at high osmolarity (i.e., they acted as osmoprotectants) on various liquid and solid defined media, while an osmoprotective effect of taurine was shown only for cells growing on high-NaCl solid medium that lacked other osmoprotectants. Potassium pool levels were high, and there was little difference in levels i...
متن کاملOsmoregulation in marine mammals.
Osmoregulation in marine mammals has been investigated for over a century; however, a review of recent advances in our understanding of water and electrolyte balance and of renal function in marine mammals is warranted. The following topics are discussed: (i) kidney structure and urine concentrating ability, (ii) sources of water, (iii) the effects of feeding, fasting and diving, (iv) the renal...
متن کاملOsmoregulation in Rhodobacter sphaeroides.
Betaine (N,N,N-trimethylglycine) functioned most effectively as an osmoprotectant in osmotically stressed Rhodobacter sphaeroides cells during aerobic growth in the dark and during anaerobic growth in the light. The presence of the amino acids L-glutamate, L-alanine, or L-proline in the growth medium did not result in a significant increase in the growth rate at increased osmotic strengths. The...
متن کاملOsmoregulation in the Antarctic nematode Panagrolaimus davidi.
A technique for determining the internal osmotic concentration of a small nematode using a modified nanolitre osmometer is described and used to investigate osmoregulation in the Antarctic nematode Panagrolaimus davidi. This technique enables the osmotic concentration to the measured with an accuracy of +/-12 mmol kg(-1). The pattern of melting in the nematode's different body compartments sugg...
