Why sourdough bread resists mold - 1 views

resistance bread mold

shared by Katelyn Madigan on 22 Feb 13 - No Cached
  • sourdough bread differs from ordinary bread in having an extra fermentation step, over and above yeast fermentation. This step is mediated by lactic acid bacteria, typically of the genus Lactobacillus
  • L. hammesii produced substantial quantities of hydroxylated monounsaturated fatty acids
  • A second antifungal fatty acid produced by cereal enzymes

    Saw this article and thought it was cool how you can use microbiology in the culinary world. Pretty awesome how some chefs desire to look into science to create signature flavors.

    Neat find, Charlie! I have thought that someone should take a more scientific approach to these "culinary microbes".

    Plants and animals living in cold climates have natural antifreeze proteins (AFPs) which prevent ice growth and crystallization of organic fluid matter.

      Looks like there's a difference of opinion.
  • decided to add further payment of $500 a person to help compensate passengers for "very challenging circumstances" aboard the ship.
  • Alletia DeMartino on 20 Feb 13
     
    A small compensation of 500$ for an inconvenience. I find it interesting that they can put a dollar amount on this. If I were these people I would be more concerned about my health than a measly 500$

DNA quadruple helix

shared by Katelyn Madigan on 07 Feb 13 - No Cached
  • our-stranded 'quadruple helix' DNA structures -- known as G-quadruplexes
  • rich in the building block guanine
  • over 10 years investigation by scientists to show these complex structures in vivo -- in living human cells
  • ...2 more annotations...
  • quadruplexes are more likely to occur in genes of cells that are rapidly dividing, such as cancer cells.
  • quadruplex DNA is found fairly consistently throughout the genome of human cells and their division cycles
  • Katelyn Madigan on 07 Feb 13
     
    A better understanding of DNA structure, as well as other factors at the molecular level, have tremendous clinical implications. A personalized inhibitory mechanism for proliferating cancer cells looks like a promising approach for cancer treatments.

    Some of the bacterial species can seed the tiny ice crystals that lead to rain, suggesting they play a role in causing rain. Bacteria have been found as far up as 24.8 miles (40 kilometers) and may even survive as spores into space.
  • Katelyn Madigan on 07 Feb 13
     
    This was a very interesting article - I had never thought of bacteria as the cause for some rain. This also would contribute to the growing issues with endospores.

    This is great news not only for what we've overlooked, but future implications that deep-sea life has a lot to offer in antibiotics. Another important factor is that we know more about the surface of the moon then our own oceans, so gives us the opportunity and a reason for categorizing deep-sea life.

How Scientists Stopped Klebsiella Pneumoniae: Deadly Superbug Killed 6 At NIH Clinical ... - 1 views

  • 18 people harbored the dangerous germ, and six died of bloodstream infections from it. Another five made it through the outbreak only to die from the diseases that brought them to NIH's world-famous campus in the first place.
  • Infections at health care facilities are one of the nation's leading causes of preventable death, claiming an estimated 99,000 lives a year.
  • KPC has emerged over the past decade to become a fast-growing threat in intensive care units, spreading easily between very ill people and killing half of those it sickens.
  • ...3 more annotations...
  • KPC was transmitted three separate times from Patient No. 1, and then spread more widely.
  • Test after test never found the bug on hospital workers' hands.
  • "There's better technology becoming available for your hospital to prevent these bacteria from spreading, and this is what you should expect from your hospital," he said.
  • Katelyn Madigan on 29 Jan 13
     
    I agree that it is wise to broaden the scope of infection control to custodial workers, since they would often be in contact with several of the inanimate objects in the room. This is really shown when they were unable to find the superbug on the "hospital workers' hands." Did they test everyone?
