Many different microbes, including several types of algae, bacteria and archaea, float in the water of Great Salt Lake. This community of free-floating microbes is often referred to as plankton, phytoplankton, or a pelagic community.

Planktonic bacteria are free-living bacteria. They are the populations that grow in the familiar test tube and flask cultures in the microbiology laboratory. The opposite mode of growth is the adherent, or sessile, type of growth. Planktonic bacteria have been recognized for centuries.

Mar 28, 2022 · The tiny size of microorganisms makes them extremely light and susceptible to every gust of wind. The airborne microorganisms floating around you are in constant motion, which is affected by the weather conditions.

Bacterioplankton are the free-floating bacteria that live throughout the water column. They are preyed upon by smaller zooplankton. Some of the bacteria in this group are autotrophic and produce their own food through photosynthesis. Others are heterotrophic and rely on other organisms for food.

Dec 3, 2022 · In a recent study published on November 30 in the journal PLOS One, a team of biologists from Sorbonne Université in France have discovered 195 species of bacteria living on microfibers...

In this study, we focus on comparisons of the quantitative results of particle-attached and free-floating bacteria in the air and the viability of these bacteria under dusty and nondusty conditions.

There was no significant pattern in the distribution of attached versus free-floating bacteria when assessed by epifluorescent microscopy. However the contribution of attached bacteria to the uptake of an amino acids mix was reduced in marine waters.

Mar 4, 2025 · Biofilms appear when previously free-floating bacteria cluster inside a self-produced slime that guards their colony. Infectious bacteria protected by a biofilm are better able to defend against antimicrobials as well as disease-fighting cells. A bacterial biofilm in a wound can impair healing and require more heavy-duty treatment.

Feb 1, 2018 · Generally, bacteria can exhibit two life states in water: free-floating (FL) or particle-attached (PA) (Fletcher, 1991).

Dec 10, 2023 · Planktonic (free-floating) cells are typically assumed to be oblivious to any flow that carries them. Here we discover that planktonic bacteria can sense flow to induce gene expression changes that are beneficial in flow.
