| clostridium oceanicum, sp. n., a sporeforming anaerobe isolated from marine sediments. | fourteen strains of a terminal-spored anaerobe were isolated from marine sediments obtained off the atlantic and pacific coasts of tropical south america. these strains are proteolytic, lecithinolytic, only slightly saccharolytic, often form cells with two spores, and appear unlike any described species of terminal-spored, proteolytic anaerobe. the name clostridium oceanicum is suggested. the type strain (no. 25647) is deposited in the american type culture collection. | 1970 | 4097533 |
| microwave processing for scanning electron microscopy. | the normal processing of biological samples for scanning electron microscopy, includes treatment with aldehyde (1 to 2 hours), postfixation with osmium (1 hour), followed by dehydration in a ascending grade of ethanol (30 a 100%), 10 to 15 minutes in each step, and finally drying. this procedure takes at least 8 hours. in this work, samples of mosquitoes (aedes), protozoa (tritrichomonas muris), bacteria (clostridium oceanicum), murine liver, and small intestine were processed in the same manner ... | 2000 | 10694907 |
| partial penetrance facilitates developmental evolution in bacteria. | development normally occurs similarly in all individuals within an isogenic population, but mutations often affect the fates of individual organisms differently. this phenomenon, known as partial penetrance, has been observed in diverse developmental systems. however, it remains unclear how the underlying genetic network specifies the set of possible alternative fates and how the relative frequencies of these fates evolve. here we identify a stochastic cell fate determination process that operat ... | 2009 | 19578359 |
