Micro-organisms bacteria

CFXI Viable micro-organisms (bacteria, yeasts mould) capable of growth under the prescribed conditions (medium, atmosphere, time and temperature) develop into visible colonies (colony forming units) which are counted. The term colony forming unit (CPU) is used because a colony may result from a single micro-organism or from a clump / cluster of micro-organisms. 

These equations are based on the assumption that at any given moment the population of micro-organisms (bacteria) in a culture will multiply as long as either there is nutrient available or, the concentration of the inhibitory product is not limiting. The rate of multiplication within the biofilm will vary according to these criteria. Belkhadir et al [1988] described the fundamental growth phases in a biofilm. The growth of active biomass is assumed to have an order of zero in relation to the nutrient and an order of unity in relation to the active bacteria so that ... 

Spectral, photophysical and photochemical properties (particularly the singlet oxygen production) of fluorescein (Figure 17) and derivatives such as Rose Bengal, eosin and erythrosin, have been widely studied. Fluoresceins and particularly Rose Bengal were widely studied for micro-organism (bacteria or yeasts) photoinactivation. 

Polymer emulsions are aqueous fluids which present a medium for the multiplication of micro-organisms (bacteria, fungi, yeasts). As the emulsions are used for the production of high quality products, including those coming in contact with food, they have to be in a clean condition when used, that means in-tank protection to prevent microbes from proliferating is necessary. 

Throughout evolution humans and animals have developed a multitude of ways for communication. Micro-organisms (bacteria, yeasts and moulds) can communicate through a process called quorum sensing. Quorum sensing is the regulation of gene expression in response to fluctuations in ceU-population density.
