Question

OVEC whole or ULTS Record your ob the information throughout the QUESTIONS 1) What is the difference between a pure culture and a pure colony? Is a streaking for isolation plate a pure culture when your original inoculum came from a mixed culture with two or more bacteria? of a tative field of cells 2) Compare and contrast the purpose and method of the streaking for isolation and the pour plate techniques. After stion e field

Answer 1

1.both pure colony and pure culture are referred to be growth obtained from a single bacterial cell, the major difference is we can count number of cells in a colony.

streaking method is used to obtain pure cultures because by streaking a dilution gradient is established across the petri plate and bacterial cells are deposited on agar surface.

2.both the technique are used to obtain pure cultures based on principle dilution gradient across agar surface in petri plate.
