HOW TO DO GROWTH CURVE OF A BACTERIA GROWN IN COLOURED SOLUTION SAY COPPER OR NICKLE?
Growth curve procedure is common for all Bacteria, whether they are growing in colour or colourless solutions.(if i am not wrong). Bacteria are all around us. Given good growing conditions, a bacterium grows slightly in size or length, a new cell wall grows through the center forming two daughter cells, each with the same genetic material as the parent cell. If the environment is optimum, the two daughter cells may divide into four in 20 minutes. Oh my! 1, 2, 4, 8, 16, 32, 64… Then why isn’t the earth covered with bacteria. The primary reason may be that conditions are rarely optimum. Scientists who study bacteria try to create the optimum environment in the lab: culture medium with the necessary energy source, nutrients, pH, and temperature, in which bacteria grow predictably. LAG PHASE: Growth is slow at first, while the “bugs” acclimate to the food and nutrients in their new habitat. LOG PHASE: Once the metabolic machinery is running, they start multiplying exponentially, doubling
