• Red yeast from deep-sea sediment shows anticancer and antibacterial properties
  

  Numerous natural products are awaiting discovery in all kinds of natural habitats. Especially microorganisms such as bacteria or fungi are able to produce diverse natural products with high biomedical application potential in particular as antibiotics and anticancer agents. This includes the so-call more

• New membranes for cellular recycling
  

  There is a constant spring-cleaning in our cells: The cell’s own recycling system, so-called autophagy, fills garbage bags with cellular waste, transports them to the recycling yard and makes the decomposed material available again. Researchers from the Max Planck Institute for Biology of Ageing hav more

• Investigating cell stress for better health - and better beer
  

  Human beings are not the only ones who suffer from stress - even microorganisms can be affected. Now, researchers from Chalmers University of Technology, Sweden, have devised a new method to study how single biological cells react to stressful situations. Understanding these responses could help dev more

• Assessing Microbial Metabolism Using A Simple ‘Mix & Measure’ Oxygen Consumption Assay
  

  MitoXpress® from Luxcel Biosciences is a water-soluble oxygen-sensitive phosphorescent probe that facilitates microplate based analysis of microbial oxygen consumption. The microbial metabolism implications of treatments such as drug exposure, geneti more

The Chemistry of Cider

Having looked at the chemistry behind beer previously, it seemed only fair to also take a look at cider for all the cider drinkers out there. On a hot summer’s day, the cool, refreshing taste of cider is hard to beat. But what are the chemicals behind this flavour? Before we look at the chemistry, l more

The Chemistry of Rum

For the latest in the alcohol chemistry series, we’re looking at a pirate’s favourite spirit: rum. It’s actually hard to describe what constitutes a rum, because there’s not really a fixed definition; different countries have different standards that rums have to meet. Still, despite the differences more

What Gives Beer its Bitterness & Flavour?

There are few things better than an ice cold beer on a hot day. Chances are, when you crack open a beer this summer, you probably won’t be thinking much about chemistry – but it’s the particular chemicals in beer, produced in the brewing process, that give beer both its bitterness and flavour. It’s more

• TPP riboswitch-dependent regulation of an ancient thiamin transporter in Candida

  by Paul D. Donovan, Linda M. Holland, Lisa Lombardi, Aisling Y. Coughlan, Desmond G. Higgins, Kenneth H. Wolfe, Geraldine Butler Riboswitches are non-coding RNA molecules that regulate gene expression by binding to specific ligands. They are primarily found in bacteria. However, one riboswitch ty more

• Microbial and Chemical Shelf‐Life of Vacuum Steam‐Pasteurized Whole Flaxseed and Milled Flaxseed

  Abstract Flaxseed is an oilseed with many health benefits. Flaxseed may be consumed raw or in processed form. In the raw form, there is a potential for microbial contamination. Several pasteurization methods have been used to reduce microbial contamination. However, such treatments may affect ch more

• Selection of Yeast Strains for Tequila Fermentation Based on Growth Dynamics in Combined Fructose and Ethanol Media

  Abstract The high concentration of fructose in agave juice has been associated with reduced ethanol tolerance of commercial yeasts used for tequila production and low fermentation yields. The selection of autochthonous strains, which are better adapted to agave juice, could improve the process. more
