So if you go up to the butcher counter and get chicken wrapped up in butcher paper, that 2 day time period to use up or freeze would be much more accurate. I give myself 1-2 days past the date on the sealed chicken before I cook or freeze.
This bacterium is also known by the names hay bacillus, grass bacillus, or Bacillus globigii. Bacillus subtilis is an endospore forming bacteria, and the endospore that it forms allows it to withstand extreme temperatures as well as dry environments. Bacillus subtilis is considered and obligate aerobe, but can also function anaerobicly when in the presence of nitrates or glucose. Bacillus subtilis is not considered pathogenic or toxic and is not a disease causing agent. Bacillus subtilis has a flagellum which makes motility faster.
There is some evidence that Bacillus subtilis might be a very small part of the normal gut flora of humans. Bacillus subtilis as normal gut flora has been theorized because soil is known to only be a reservoir for the bacteria, and it needs a host to live in to be able to function.
