During a gram stain some bacteria retains the stain because they are gram positive with thicker walls . If the bacteria does not stain either it is an endospore bacteria or gram negative with thinner walls, so colorless or red color.
Biologist group most species of bacteria into two categories based on structures of their cell walls. Gram-negative bacteria have cells walls that are complex and and have small amount of peptidoglycan. Gram-negative bacteria take up the second, red dye of the Gram stain process which makes the cells appear reddish pink. Gram-positive bacteria are simpler and have much more peptidoglycan which retains the purple in their cell walls and appear purple.
Some bacteria test Gram positive because they have a thick cell wall made up of peptidoglycan that traps the crystal violet in the cytoplasm. Others test Gram negative because they have a thinner layer of peptidoglycan and crystal violet is easily rinsed from the cytoplasm.
Gram-positive bacteria have a cell wall consisting of a plasma membrane, periplasmic space, and a peptidoglycan layer.
Gram-negative bacteria have the same cell wall structures as gram-positive bacteria. However, they have an additional periplasmic space and outer membrane made of lipopolysaccharide and protein.
Ecoile and Natural Bacteria (Which form some natural springs)
It really depends on the bacteria. Some multiply best at room temperature, some at 60 deg celcius. Bacteria has 4 phases in life. The lag, log/exponential, stationary or the death phase. Bacteria multiply best at its log phase. The log phase depends on the bacteria species.
Bacteria are tiny living things. Some bacteria are good and some are not good. The difference between bacteria and a microbe, is a word used to describe tiny living things, which means that bacteria is a microbe, however, not all microbes are bacteria. A microbe can also be fungi, and protists, as well as bacteria.
Some examples of good bacteria is yeast for the bread most of us eat, but bacteria can also be bad. Some bad bacteria is E.Coli. which tears our insides apart, or makes us veryyyyy sick. Some examples of good bacteria is yeast for the bread most of us eat, but bacteria can also be bad. Some bad bacteria is E.Coli. which tears our insides apart, or makes us veryyyyy sick. Good bacteria is freindlly and benefical microorganism that lives in the body to keep the body healty.
Plenty. They are known as pathogenic bacteria. Visit the bacteria museum online,
B. Subtilus is a rod or bacilus shaped, gram positive bacteria
to eliminate gram positive bacteria from a mixture of grampositive and gram negative bacteria which procedure would be best first treatment with mild detergent or lysoyme
negative!
Amoxicillin is for penicillin class of antibiotics. By inhibiting the synthesis of bacterial cell walls, it makes the bacteria expanding and cracking to take sterilization effects. It has good antibacterial activity for the hemolytic streptococcus, pneumonia streptococcus, penicillin enzyme aureus, dung enterococcus, singular proteus and other aerobic gramnegative bacteria and so on. Amoxicillin sodium for injection is suitable for a variety of infections caused by sensitive bacteria for the heavy patients requiring hospitalization or not being able to take by mouth.

some genes are skinny some are boot cut but bacteria are bacteria
Some bacteria are beneficial to humans, and some bacteria are harmful to humans.
no, some bacteria are heterotrophic and some are autotrophic. Most bacteria are heterotrophic though.
Bacteria do like fruit - at least, some bacteria will do very well on some fruit.
Yes, Some bacteria are red.
There are no bacteria on other bacteria. Some bacteria do attack other bacteria by piercing their cell wall and injecting proteins.Viruses can attack bacteria. They are called bacteriophages.
Yes. Most bacteria is not harmful to us such as bacteria in a yogurt, but some bacteria is harmful.
yes some bacteria are good and some are bad for exsample one bacteria helps you digess food
