philips eco-friendly microbial home methane bio-digester the 'bio-digester' is a kitchen island that includes a chopping surface with waste grinder and gas cooking range. in the device, 'bio-gas' is produced by developing gas-generating bacteria cultures that live off of organic waste. the bacterias' gas is collected and burnt, for use in the built-in cooking range and lights or sent through to heat water pipes and be used in other components of the 'microbial home'.

High-Tech meets eco

The Swiss designer Beat Karrer researches new processing methods of bio-degradable plastics... organic plastics are so-called biopolymers – molecule chains of greater or lesser length which are formed from living organisms, in other words of vegetable (starch, cellulose, pectin), bacterial (polylactic acid) or animal origin (gelatine, wool, silk etc.). They can be supplemented by reinforcing materials such as natural fibre or filling matter.

The bio-light uses different biological technologies to create ambient light effects. The concept explores the use of bioluminescent bacteria, which are fed with methane and composted material (drawn from the methane digester in the Microbial Home system). Alternatively the cellular light array can be filled with fluorescent proteins that emit different frequencies of light.

Suzanne Lee, director of Biocouture, in her London studio, where she's using cellulose-producing microbes to grow garments in a vat of fermenting liquid... she developed a process of growing microbial material in a mixture of green tea, sugar and yeast to create a completely natural, 100% compostable product. The material can be dried, cut and sewn together to make clothes. Extract from The Next Black. Full film at -

Although the bacterial component of a kombucha culture comprises several species, it almost always includes Gluconacetobacter xylinus (formerly Acetobacter xylinum), which ferments the alcohols produced by the yeast(s) into acetic acid. This increases the acidity while limiting the alcoholic content of kombucha. G. xylinum is responsible for most or all of the physical structure of a kombucha mother, and has been shown to produce microbial cellulose.
