O consumo, especialmente em sociedades capitalistas, não está ligado apenas ao valor funcional dos produtos, mas também aos símbolos que eles representam. (MCCRACKEN 1986; 2003; FEATHERSTONE 1995). Nessas sociedades, as posses tem influência na construção da identidade do indivíduo, que busca produtos para se associar a grupos ou a sub ¿ grupos no s

2. Reductive dechlorination of Tri- and tetrachloroethylenes depends on transition from aerobic to anaerobic conditions.
Aerobic enrichment cultures from contaminated groundwaters dechlorinated trichloroethylene (TCE) (14.6 mg/liter; 111 mumol/liter) and tetrachloroethylene (PCE) (16.2 mg/liter; 98 mumol/liter) reductively within 4 days after the transition from aerobic to anaerobic conditions. The transformation products were equimolar amounts of cis-1,2-dichloroethylene and

3. Anaerobic oxidation of ferrous iron by purple bacteria, a new type of phototrophic metabolism.
Anoxic iron-rich sediment samples that had been stored in the light showed development of brown, rusty patches. Subcultures in defined mineral media with ferrous iron (10 mmol/liter, mostly precipitated as FeCO3) yielded enrichments of anoxygenic phototrophic bacteria which used ferrous iron as the sole electron donor for photosynthesis. Two different types
