Abstract
For the simple expediency of accommodating the interests of every member of this group, we define a microbial aggregate as a collection of microbial cells in intimate contact. This definition, agreed upon by the majority, avoids any connotation of mechanism as to origin and genesis of the collection. It is not in agreement with the more restrictive definition put forward by some of us: a gathering followed by a binding together. An aggregate, as treated here, is a structure — the product of a process. Aggregation is one of the processes that may lead to an aggregate. Thus, a microcolony on a solid surface falls into this category; likewise, a biofilm, as used by the other groups. However, a biofilm needs a substratum to which cells attach, whereas a floc most often does not. Moreover, flocs are transportable entities, whereas biofilms are more or less stationary.
