Bleached cells of Scenedesmus sp. were re-incubated in polyethylene tubes containing 2000 mL of culture volume with different nutrient supplementations. Dry weight (g L-1) and total chlorophyll (mg L-1) were daily measured. Death and growth-rate of out door grown cells were calculated before the indoor re-cultivation, where other growth parameters including growth rate, doubling time, degree of multiplication and percentage increase were daily determined during the recovery period. Growth as dry weight and total chlorophyll was decomposed and cultures reached their minimum biomass at nearly to 12th day. Recovery period represented variable increases own to the rate of nutrient supplementation and incubation mode, where diluted and semi-diluted cultures represented the maximum. Higher growth rate of the dense cultures could be attributed to the initial biomass at zero time. Consequently, failure of growth during the sunny season could be ascribed to the effect of high light intensity as well as the generated temperature. |
