What is the bacteria mophology for bacillus subtilis by simple stain?

B. subtilis is indeed a Gram positive rod.
However, there is confusion as to whether it is an obligate aerobe or a facultative anaerobe. Although classed as an obligate aerobe, it has been shown to grow under strict anaerobic conditions.

∙ 13y agoIn an acid-fast stain, positive acid-fast bacterium will appear red because they possess a lipid mycolic acid on their membrane and will retain heated carbolfuchsin. Negative acid-fast bacterium will appear blue (stained by methylene blue). Myobacterium and nocardia are negative acid-fast bacterium. All the rest of bacterium (i.e. bacillus) are acid-fast positve.

Whoever gave that answer above should not be posting anything again. That answer is completely wrong (except for the explanation). Mycobacterium and Nocardia are acid-fast positive. I don't know what all the bacteria are that give off a negative, but Bacillus subtilis and Corynebacterium are acid-fast negative.

∙ 11y agoBacillus subtilis retains crystal violate dye in both the simple stain and the gram stain. Thus, the morphology of the organism is the same after both procedures. Regardless of simple stain or gram stain, if you know you're dealing with B. subtilis, you'll see purple rods that are sort of clustered together. Remember that the simple stain is only really used to increase contrast between the organism at hand and the field of view in the microscope.

Are bacteria metabolically complex or simple?
Prokaryotic cells (Bacteria) are structurally simplebut! Metabolically complex
What is the difference between viral and a bacteria infection?
As simple as that a viral infection is caused by a virus and a bacterial infection is caused by a bacteria.
What will bacteria do with products for starch hydrolysis?
Let me guess, this question is for a lab write up in your microbiology class? When your bacteria, probably Bacillus cereus, act on starch they produce glucose. You have probably already done this lab but the bacteria will ferment the glucose. E.coli does not hydrolyze the starch because it does not produce amylase (which break down the starch into simple sugars).
Why is the gram stain technique more valuable than the simple stain technique in the diagnostic laboratory Under what circumstances might the simple stain be preferable to the gram stain technique?
There are two types of stains, the simple stain and the differential stain. A simple stain colors all objects the same while a differential stain is used to spot differences in microorganisms. A gram stain is a differential stain, which is used to tell the difference in gram negative and gram positive bacteria. A simple stain would stain all the organisms the same and this difference would not be noted. You would be able to determine their shape, whether it is a cocci or bacillus (rod), but not the type. I'm not sure why the simple stain would be preferable unless you just wanted a quick answer as to the shape of the bacteria. In some cases, a wet prep can be made of a presumptive gram positive cocci to tell the difference between bacteria or yeast. Otherwise, I would say that the gram stain is the only way to go.
Microscopic single-celled simple plants?
Bacteria or bacterium are the microscopic single-celled simple plants some are harmful and some are helpful. Bacteria constitute a large domain of prokaryotic microorganisms.
Why is bacillus subtilis able to grow after exposure to even 80 degrees Fahrenheit?
The simple answer is that Bacillus is capable of producing endospores. Endospores can withstand a wider variety of extreme conditions that would be harmful to other cells - such as radiation, abrasion, extremes of heat and cold, and lack of nutrients and water.
Do bacillus live in extreme environments?
Most extremophiles are simple, single-celled life forms, yet many are not. Extremophiles occur in all three domains of life: bacteria, archaea, and eukaryotes. ... However, archaea aren't restricted to extreme environments; they live in most of the same places as bacteria
What does a simple stain of bacillus megaterium look like under a microscope?
Simple or gram? Simple uses methylene blue, gram uses crystal violet
What is a simple bacteria?
a simple organism is divided into 5 groupes;viruses,bacteria,protozoa,algea and fungi..
What color is simple staining on a bacillus and coccus using methylene blue stain?
Methylene blue stains everything blue.
Are bacteria considered simple organisms why or why not?
Bacteria are considered simple organisms because they are single celled, they do not have a nucleus with a membrane and no membrane-bound organelles.
What are bacteria cells?
Bacteria are unicellular organisms that have a cell wall but do not have a nucleus. They have DNA material that are of two types - plasmids and chromosomal. Chromosomal DNA have genetic information and the plasmids have extra information that gives the bacteria genetic advantage such as antibiotic resistance. Some bacteria have a whip like flagellum that helps the bacteria to move along.
Are bacteria metabolically complex or simple?
Prokaryotic cells (Bacteria) are structurally simplebut! Metabolically complex
Why are protist and bacteria called simple organisms?
unicellular
Is mold a simple animal?
no, mold is a bacteria or fungus
Is bacteria growth is mostly a simple increase in size?
no.
Do bacteria decompose other bacteria?
Some bacteria will consume other bacteria, but in general, individual bacterium are simple enough organisms that they break down entirely on their own.
