Bacteria from cold environments may prove useful in making green, energy-saving detergents

September 25, 2018 -

The idea for using them as such is based mainly on the fact that they possess certain abilities. Biosurfactants are best described as surface-active molecules which are made up of both hydrophobic (water-repelling) and hydrophilic (water-loving) parts. Combined, these components are known to work together to reduce surface tension as well as interfacial tension between aqueous solutions and hydrocarbon mixtures.

Due to the fact that biosurfactants are relatively non-toxic ...

Bacteria in your small intestines may explain why you gain weight

May 16, 2018 -

In the animal study, a team of researchers from the University of Chicago found that germ-free mice lacking in gut bacteria failed to digest or absorb fatty foods when fed with a diet high in fat. In addition, these mice were also unable to gain weight and produce fatty stools. On the contrary, specific pathogen free (SPF) mice – which had a healthy gut microbiota but lack certain disease-causing species – were found to rapidly gain weight when fed with a high-fat diet....

Bacteria-eating viruses may be effective at eliminating foodborne pathogens; could be used to prevent food poisoning

March 13, 2018 - bacterial infections are multi-drug resistant – with some bacteria even found in meat products.

The mechanisms of SILVER against deadly bacteria and why it should be in your prepper bag

March 15, 2024 -

A May 2015 piece in Science magazine stated that silver interferes with the cell walls of bacteria and deprives them of the normal metabolic processes they need to survive. Silver ions punch holes in bacterial membranes and, once inside, bind to essential components like DNA. This, in turn, prevent bacteria from performing even their most basic functions.

The magazine also referenced an April 2015 study published in Scientific Reports about this ...
