Mixed culture

Under conditions of oxygen limitation in continuous culture, mixed populations of aerobic bacteria and the strictly anaerobic Methanobacterium formicicum and Methanosarcina barkeri could be maintained (Gerritse and Gottschal 1993a).

Sinclair et al. (79) have compared the environmental (primarily carbon) footprint of a monoclonal antibody (mAb) production facility using traditional stainless steel bioreactors with that of a facility utilizing disposable equipment for cell culture, mixing solutions, holding tanks, and liquid transfer. The mAbs are intended for use in therapeutic applications and are produced in a facility containing three 2000-L disposable bioreactors. The authors cradle-to-grave analysis took into account facility... 

Transformations performed with one or more cultures (mixed or sequential) are recorded at the end of the list of substrates for the given species. Only the reaction carried out by the primary culture is cited in the reaction column.

In cases where steady-state conditions are achieved, Donnan dialysis can be effectively integrated with Hg(II) bioreduction to Hg(0) using mixed microbial cultures. While many organisms have been shown to perform Hg(II) bioreduction in pure culture, mixed microbial cultures offer the advantage of not requiring aseptic operational conditions, and can thus be much more readily integrated with the lEMB process, where aseptic conditions would involve additional operational costs and complicate the process unnecessarily. Efficient Hg(II) bioreducing mixed cultures have...
