B means the are of the base while b means the base line.
There is no difference between improper subset and equal sets. If A is an improper subset of B then A = B. For this reason, the term "improper subset" is rarely used.
This function will accept two parameters and return the difference between the first and second parameter. function diffBetween ( a, b ) { return a-b; } //end diffBetween
streptomycin ihibits growth of b. subtilis
Staph gives both MR and VP positive. MR is used to detect acid production and VP for alkaline or neutral products. Staph first converts into acidic products and has ability to convert those acidic products into some neutral/basic products side by side. Hence it gives both positive results.
Bacillus megaterium is a facultative anaerobe, meaning it can grow in both the presence and absence of oxygen. This bacterium has the ability to switch between aerobic and anaerobic metabolism depending on the availability of oxygen in its environment.
Selective media for Bacillus subtilis typically contain antibiotics such as neomycin or polymyxin to inhibit the growth of other bacteria while promoting the growth of B. subtilis. Other components may include specific carbon sources or pH indicators to aid in differentiating B. subtilis colonies from others.
gamma/alpha hemolysis
Yes, Bacillus subtilis has the capability to hydrolyze starch due to the production of amylase enzymes. Amylases secreted by B. subtilis break down starch into simpler sugars such as maltose and glucose that can be utilized by the bacterium for growth and metabolism.
gram positive Exactly. When doing a gram stain on B. subtilis, this bacterium resists decolorization (keping the first stain and NOT taking on the color of the secondary stain). Therefore, this bacterium is gram (+).
Temperature can affect the growth rate and metabolism of Bacillus subtilis. Higher temperatures can promote faster growth and enzyme activity, while extreme temperatures can denature proteins and disrupt cellular processes. Overall, temperature can impact the physiological behavior and survival of B. subtilis.
no answer
Bacillus subtilis typically forms large, dry, irregular colonies with a matte appearance on MYP agar, while Staphylococcus aureus usually forms small, smooth, shiny colonies. Additionally, B. subtilis is often motile and may exhibit rhizoid growth patterns, while S. aureus is non-motile. A Gram stain can also be useful, as B. subtilis is Gram-positive and S. aureus is Gram-positive.
what is the difference between utilization category A and B of MCCB's
Bacillus subtilis is a rod-shaped bacterium. The appearance of holes in some B. subtilis cells may be due to the presence of endospores within the cell. Endospores are resistant, dormant structures formed by some bacterial species under unfavorable conditions, and they can sometimes create the appearance of holes in the cell when observed under a microscope.
