Which Aerobic Bacteria Are Used In Sewage Treatment? Bacteria belonging to the following genera showed up in sewage and sludge samples: species such as Actinomyces, Bifidobacterium, Clostridium, Propionibacterium, and Staphylococcus, as well as Clostridium.
Which bacterial genera plays an important role in environmental nitrogen cycles?
The primary ecological role of members of the genus Nitrobacter is to oxidize nitrite to nitrate, a primary source on inorganic nitrogen for plants. This role is also essential in aquaponics.
Which of the following bacterial genera plays an important role in environmental nitrogen cycles quizlet?
Which of the following bacterial genera plays an important role in environmental nitrogen cycles? in the phylum Firmicutes and include Clostridia and Mycoplasma.
Which of the following bacterial genera produces endospores?
Endospores are dormant alternate life forms produced by the genus Bacillus, the genus Clostridium, and a number other genera of bacteria, including Desulfotomaculum, Sporosarcina, Sporolactobacillus, Oscillospira, and Thermoactinomyces.Jan 3, 2021
What feature of mycobacteria is responsible?
What feature of mycobacteria is responsible for the unusually slow growth of these bacteria? The mycolic acid in their cell walls requires signification metabolic investment.
Which of the following bacterial genera has an outer membrane?
gram-negative bacteriaOne of the several unique characteristics of gram-negative bacteria is the structure of the bacterial outer membrane. The outer leaflet of this membrane contains lipopolysaccharide (LPS), whose lipid A portion acts as an endotoxin.
What are flexible spiral shaped bacteria called?
Spirilla (sing. spirillum) shapes are curved-shaped bacteria which can range from a gently curved shape to a corkscrew spiral.
Do all bacteria have flagella?
Yes. Flagella are present in both Gram-positive and Gram-negative bacteria. Bacterial flagella are microscopic coiled, hair-like structures, which are involved in the locomotion.
Which of the following characteristics can be used to differentiate between the genera Bacillus and Clostridium?
Microbiologists distinguish Clostridium from Bacillus by the following features: Clostridium grows in anaerobic conditions; Bacillus grows in aerobic conditions. Clostridium forms bottle-shaped endospores; Bacillus forms oblong endospores.
Which of the following genera can be described as a non-motile aerobic Gram-negative rod?
Acinetobacter baumannii is a Gram-negative bacillus that is aerobic, pleomorphic and non-motile.
Is Mycobacterium a fungus or bacteria?
Mycobacteria are characterized by the possession of very thick, waxy, lipid-rich hydrophobic cell walls. Being hydrophobic, they tend to grow as fungus-like pellicles on liquid culture media: hence the name Mycobacterium – 'fungus bacterium.
How mycobacteria SPP is it different from the other bacteria?
Mycobacteria differ so strongly from other bacteria in their cell wall architecture and metabolism that they require specific diagnostic tests, i.e. stains, culture media, identification methods.
What function do bacterial endospores perform?
It allows the bacterium to produce a dormant and highly resistant cell to preserve the cell's genetic material in times of extreme stress. Endospores can survive environmental assaults that would normally kill the bacterium.
What are the diseases caused by Staphylococcus aureus?
7) Some strains of Staphylococcus aureus can invade the body and cause diseases such as pneumonia and bacteremia. A. 8) Mycoplasmas are named for the large quantities of mycolic acid in their cell walls. B.
Why are streptomyces important?
3) Members of the Streptomyces are environmentally important because they can degrade a wide range of compounds including lignin from trees, chitin and keratin from animals, and latex. A. 4) Halophiles grow equally well in the presence or absence of high salt concentrations. B.
