Drying bacterial biosaline patterns capable of vital reanimation upon rehydration: novel hibernating biomineralogical life formations.
Water is the fundamental molecule for life on Earth. Thus, the search for hibernating life-forms in waterless environments is an important research topic for astrobiology. To date, however, the organizational patterns containing microbial life in extremely dry places, such as the deserts of Earth, the Dry Valleys of Antarctica, or Mars analog regolith, have been poorly characterized. Here, we r...
متن کاملThe survival of Escherichia coli on drying and rehydration.
By direct observation of individual organisms in a micro-culture chamber and by viable plate counts, a study has been made of the function of sugar/colloid mixtures in promoting the survival of Gram-negative bacteria on drying. The high death rate after drying in sugar alone was due mainly to cell-wall damage caused during rehydration by the temporary osmotic pressure set up by the sugar within...

متن کاملDNA denatures upon drying after ethanol precipitation.
We have observed that ethanol precipitation and subsequent drying of small (less than 400 bp) radiolabelled DNA fragments is able to induce a transition to a form that migrates aberrantly on acrylamide gels. This unusual form has increased sensitivity to S1 nuclease, decreased sensitivity to restriction enzymes, and a concentration dependence for the reversion to the duplex form. Apparently, DN...
متن کاملStreptococcus pneumoniae Is Desiccation Tolerant and Infectious upon Rehydration
UNLABELLED Streptococcus pneumoniae (pneumococcus) is a frequent colonizer of the nasopharynx and one of the leading causative agents of otitis media, pneumonia, and meningitis. The current literature asserts that S. pneumoniae is transmitted person to person via respiratory droplets; however, environmental surfaces (fomites) have been linked to the spread of other respiratory pathogens. Desicc...
