The primitive form of sex enacted by protists
is called conjugation, and it is entirely separate from the reproductive process.
Matthew Brown, assistant professor of biological sciences at Mississippi State University, recently led a research team that identified the protist
as a new organism and classified its genomics.
The toxicity was evaluated by determining the IC 50, which determines the concentration which, under standard conditions, inhibits 50% of the increase in population , and the percentage of response which assesses response of protists
in respect of the pollutant, according to the equation :
In return, said Bernhard, "the bacterial symbiont benefits because the protist
can migrate to wherever the right geochemical conditions are, and that's keeping the bacteria in a 'happy place.
Jake Bailey from the University of Minnesota and Philip Donoghue from University of Bristol negate the fact that the fossils represent bacteria, strengthening the theory that the fossils are either animals or some type of protist
, possibly other than bacteria.
Rhynchodida-like ciliates, encapsulated copepods, and an unknown protist
According to Diana Lipscomb, a protist
taxonomist at George Washington University in Washington, D.
Schechter commented, "Pyro's pending patents reflect a number of important disease causing bacteria, protist
, yeast, and fungal microorganisms in which an essential pathway is required for viability, including but not limited to the following bacteria causing diseases.
Jiang and his team conducted experiments with 10 common ciliated protist
species in artificial, simplified ecosystems called microcosms.
Some of the critters, including members of two major protist
groups--the whip-tailed flagellates and hairy ciliates--harbor bacteria internally.
Broad spectrum antibiotics treat a variety of gram-positive and gram-negative bacteria, protist
, yeast, and fungal organisms, while mild spectrum antibiotics only cover limited types of bacterial, protist
, yeast, and fungal organisms and are useful for curing infections with known bacterial, protist
, yeast, and fungal strains.
To test this possibility, Edgcomb is examining whether bacteria digest oil differently in the presence and absence of protist
