Witryna14 wrz 2024 · Archaea exhibit a higher level of morphological diversity compared with bacteria. Spherical, spiral, flat, square- or rod-shaped, and Gram-negative or Gram-positive Archaea live as isolated cells, aggregates, or filaments and multiply by binary fusion, budding, or fragmentation. WitrynaTwo haloalkaliphilic archaea were isolated from a soda lake in Tibet. The two strains, designated A33T and GA33T, were Gram-negative, pleomorphic, flat, non-motile and strictly aerobic. Growth required at least 12% NaCl. Growth was between pH 8.0 and pH 11 with an optimum at pH 9.0-9.5. Cells were chemo-organotrophic.
