The phrase "aggregations of bacteria" is correct and usable in written English.
It can be used in scientific or medical contexts to describe clusters or groups of bacteria that come together.
Example: "The study focused on the aggregations of bacteria found in the human gut microbiome."
Alternatives: "clusters of bacteria" or "groups of bacteria."
"One of the ways staph works is by creating aggregations of bacteria that block blood vessels and airways," Schlievert says.
As a first step to test our findings, spectral comparisons were made with two bacterial biofilms (i.e., 3-dimensional aggregations of bacteria within a cohesive exopolysaccharide matrix [25]) and with a bacterial collagen-like protein [13] to assess the possibility of protein contamination from modern microbial sources.
Keller and Segel proposed it as a model of aggregation of bacteria, which is mathematically translated as finite-time blowup.
In cell biology, bands have been used to describe the aggregation of bacteria via chemotaxis [33 37].
Investigation of the cost and benefits of co-growth for bacteria and algae with an emphasis on chemotactic aggregation of bacteria around phytoplankton cells.
At this bactericidal concentration of Ag NPs, the black aggregates of E. coli were clearly visible floating in the growth media showing the aggregation of bacteria.
Protruding topographical features on the other hand have been shown to decrease the biofilm growth kinetics and enhance the aggregation of bacteria.
The aggregation of bacteria at bactericidal concentration of many antimicrobial agents is already known and is usually attributed to the charge neutralization of bacterial cell's surface in case of PHMB [24].
A biofilm is a layer-like aggregation of bacteria and their extra cellular polymers (Rittmann and McCarty 1980; Hinson and Kocher 1996) that is attached to a solid surface and thus a common form of microbial ecosystem associated with surfaces.
The improvement in biogas yield could be due to aggregation of bacteria and methanogens around the particles, leading to a lower washout and higher culture densities; it is also possible that metal particles release electrons to the surrounding medium, which can be used for methane formation, but the exact mechanism remains unclear (Yadvika et al. 2004; Carpenter et al. 2015).
Epidemiological and pathological findings, including sporadic incidents of severe invasive GAS infections [9], high frequency of severe invasive infections in immunocompromised host [9], and aggregation of bacteria and a paucity of polymorphnuclear neutrophils (PMN) in foci of invasive GAS infection [10] suggest that host defense factors play an important role in the onset of invasive infections.
