If my cultures are suffering severely due to alkaloid production and accumulation in the medium, how can I overcome this problem?
Step by step
Solved in 2 steps
- If my cultures are suffering severely due to alkaloid production and accumulation in the medium. In that case, how can I overcome this problem?If my tissue cultures are suffering severely due to alkaloid production and accumulation in the medium. In that case, how can I overcome this problem?The difference in the colony appearance of bacteria cells growing on mannitol salt agar is detected by a) methyl blue b)methyl red c) phenol d) eosin e) salt .
- During media preparation, you observed that the agar medium did not solidify after sterilization even after incubating it for 1 hour at room temperature. What could be the reason behind this?If lysozyme is added to a microbial culture. Predict what will be observed if the culture is affected by the action of lysozyme. A change in color will be visible in the tube. An increase in absorbance will be observed over time. A decrease in absorbance will be observed over time. An increase in turbidity will be observed over time.Spores and toxin-producing microorganism produce toxins need higher Aw than minimum Aw for microbial growth. How could food industry benefit from this fact?
- Can culture media be sterilized in the hot air sterilizer? Why or why not?while working with mannitol salt agar you notice the growth of staphylococci however other microorganism are growing as well. how would you interpret this?Agar is a solidifying agent used in media preparation. What makes it ideal for cultivation of microbes?
- How is UV radiation a good type of control mechanism against microbial growth? Please explain what happens to the microbe and effects this control causes.Of what practical importance are air borne microorganisms to the laboratory workers? What precautions should be taken to control laboratory contaminants? Of what advantage is the using a solid and a liquid medium?Need help Can a pure culture be prepared from a mixed culture in a broth or plate? Explain.
