Question

What is the min,max, and optimal, osmotic pressure of extremel halophiles and osmotolernt microbes?

Answer 1

Osmotolerant microbes are those microbes that could tolerate very high amount of osmolarity. This may be in the form of both sugar and salt. But the term osmophiles is generally used for the bacteria that could tolerate high amount of sugar concentration. Halophiles are bacteria that require salt for their growth. Most of the extreme halophiles belong eto the group archae. Depending on the amount of salt tolerance, halophiles could be classified as

- slight halophiles:

minimum value: 0.34M

Maximum value: 0.85M

Optimal value: 0.34-0.85M

- moderate halophiles:

Minimum value: 0.85M

Maximum value: 3.4M

Optimal range: 0.85 - 3.4M

- extreme halophiles:

Maximum value: 5.1M

Minimum value: 3.4M

Optimal range: 3.4 - 5.1M
