| mobilifilum chasei: morphology and ecology of a spirochete from an intertidal stratified microbial mat community. | spirochetes were found in the lower anoxiphototrophic layer of a stratified microbial mat (north pond, laguna figueroa, baja california, mexico). ultra-structural analysis of thin sections of field samples revealed spirochetes approximately 0.25 micrometer in diameter with 10 or more periplasmic flagella, leading to the interpretation that these spirochetes bear 10 flagellar insertions on each end. morphometric study showed these free-living spirochetes greatly resemble certain symbiotic ones, ... | 1990 | 11538692 |
| spirochaeta bajacaliforniensis sp. n. from a microbial mat community at laguna figueroa, baja california norte, mexico. | a new anaerobic spirochete was isolated from anaerobic muds beneath the laminated sediment in the evaporite flat at laguna figueroa, baja california norte, mexico. the organism is a member of the stratified microbial community involved in the deposition of the laminated sediments in the lagoon. the size of the spirochete is 0.3 by 30 micrometers, with a wave amplitude of 0.5 micrometer and a wavelength of 1.25 micrometers. the periplasmic flagella have a 1-2-1 arrangement. the outer membrane ... | 1985 | 11542001 |
