Many bacteria required special nutrient and enviornmetn for their grwoth and reproduction and they can not survive without them. These type of bacteria are more sensitive in culture process. e.g. Nesseria gonorrhoeae needs blood agar to grow rather then normal nutreint agar medium.
What else can I help you with?
Which are more sensitive to penicllin?
Gram-positive bacteria are generally more sensitive to penicillin than Gram-negative bacteria. This is because the cell wall of Gram-positive bacteria is more susceptible to the action of penicillin, while Gram-negative bacteria have an outer membrane that provides some protection against the antibiotic.
Which is more sensitive to penicillin gram posite or gram negative?
Gram-positive bacteria are generally more sensitive to penicillin compared to gram-negative bacteria. This is because gram-positive bacteria have a thinner cell wall that is easier for penicillin to penetrate and disrupt, leading to cell death. Gram-negative bacteria have an outer membrane that provides some protection against penicillin, making them less susceptible.
How would you define pure culture sterile and contamination in the isolation and purification of bacteria?
A pure culture is defined as a population containing only a single species or strain of bacteria. Contamination means that more than one species is present in a culture that is supposed to be pure.
How do bacteria typically reproduce?
Bacteria generally reproduce by splitting in half, a process called Mitosis. They are asexual reproducers. it is more commonly called binary fission.
What is the process called in which cultures become more and more similar to one another?
Cultural convergence

What Positive Adaptations?
Positive adaptation which is also called sensitization is a type of sensory adaptation in which we become more sensitive to stimuli that are low in magnitude. It is the process of becoming for sensitive.
What is the comparative and superlative of the word sensitive?
Comparative: more sensitive Superlative: most sensitive
Why is turbidity not an accuarte measure of viable bacteria in a culture?
Turbidity measures the cloudiness of a culture, which can be influenced by various factors besides viable bacteria, such as debris or particles in the solution. Viable bacteria may also form clusters or biofilms, which can affect turbidity readings. To accurately measure viable bacteria, other methods such as colony counting or molecular techniques are more appropriate.
What is anglicized?
Anglicization is the process of making something, particularly a word within language or culture, more English.
How could you tell the bacteria were growing in the culture?
Bacteria growth can be detected by an increase in turbidity (cloudiness) of the culture, formation of colonies on agar plates, or by changes in pH or color of the medium due to metabolic byproducts. Additionally, observing the presence of a pellicle, sediment, or turbidity in a liquid culture can indicate bacterial growth.
Why does this exercise call for an older 5 day culture of bacillus?
Using an older culture allows the bacteria to reach the stationary phase in growth, where they are more metabolically active and produce spores, making it easier to observe characteristics such as spore formation or motility. It also ensures that the bacteria are in a consistent growth phase for accurate comparisons between samples.
How do bacteria typically reproduce?
Bacteria generally reproduce by splitting in half, a process called Mitosis. They are asexual reproducers. it is more commonly called binary fission.
How do bacteria make more of themselves?
Bacteria reproduce through a process called binary fission, where a bacterial cell splits into two identical daughter cells. During binary fission, the bacterial cell replicates its DNA and then divides the cell into two new cells. This process allows bacteria to rapidly multiply and increase their population.
