The most common method is spreading microbes across a plate as shown in the first four figures. As the concentration of microbes increases so do the number of phases.
Webstreaking step is followed by a flaming step. As bacteria are streaked from one area of the plate to the next, a dilution occurs. At the last streak, the number of cells on the loop should be small. As these small number of cells are spread across the remaining area of the plate, the cells are physically separated. Each isolated cell will ... WebThe streak plate method of isolation means to spread the microbes on plated agar media so that the individual cells or colony forming units (CFUs) can become isolated and grow into individual, pure colonies. The method …
WebSpreading techniques are characterized by a deliberate temporal or spectral spreading which leads to signals having time-bandwidth-products much larger than unity. Spreading techniques offer a number of advantages in various fields of modern information technology like information transmission, channel identification or time and frequency ...
