The microbes that give cheddar cheese its distinct flavour

Cheddar cheese's distinct but often subtle flavour comes down to interactions between different bacteria, which cheese-makers could utilise to create a specific taste

Features
T-bacteriophages on E.coli. Coloured Transmission Electron Micrograph (TEM) of T-bacteriophage viruses attacking a bacterial cell of Escherichia coli. Seven virus particles are seen (blue), each with a head and a tail. Four of these are "sitting" on the brown bacterial cell and small blue "tails" of genetic material (DNA) are seen being injected into the bacterium. T-bacterio- phages are parasites of bacterial cells. The virus attaches itself to the cell's wall and, using it's tail as a syringe, injects it's own DNA into the bacterium. The virus DNA then takes over the bacterial cell, forcing it to produce more viruses. Magnification: x63,000 at 5x7cm size.

Trichodesmium thiebautii (light micrograph) Trichodesmium thiebautii is a cyanobacterium, or blue-green alga, that forms colonies of cells. In high concentrations, they create golden-brown surface mats, often referred to ?sea sawdust,? in the Gulf of Mexico. These large concentrations, called blooms, are sometimes associated with fish kills and can cause dermatitis or ?swimmer?s itch? when handled or contacted. When blooms die and decay, they can discolor the water pink to red. Toxin production by this species is being investigated. https://www.flickr.com/photos/myfwc/8678780050
