Abstract:
Listeria monocytogenes was able to grow in multispecies biofilms formed on stainless steel at 10°C in the presence of bacteria isolated from dairy and meat plant environments. Biofilm L. monocytogenes increased more slowly in the presence of competing microflora than in monoculture, but none of the eight competing isolates studied were able to completely exclude L. monocytogenes from the biofilm within 25 days of incubation. Once a population of L. monocytogenes was established on the surface, it invariably increased in numbers. In biofilms containing a mixture of 4 competitive cultures, L. monocytogenes maintained itself at about 1% of the total population.

Cyclic Processes And Isolated Systems
In the case of a non-isolated system, the change in the internal energy is zero only if the process is cyclic. A thermodynamic process is considered cyclic if the system undergoes a series of changes and returns to its initial state.
Consider a cyclic process that returns to its initial state, undergoing a four-step process. The heat transfer along each...
