Abstract
1-The results show clearly that the growth parameters of Chlorella at 22'C was more intense than other temperature degrees , which recorded maximum production during the period of 6 days of culture age , while growth ofScenedesmus at 17'C which recorded the best results were increasing until the end of incubation periods . The relative high temperature at 32'C led to a depression in growth of Chlorel/a sorokiniana and Scenedesmus dimorplrus.
2- The results showed that growth parameters of Chlorel/a and Scenedesmus at 12000 Lux was
reached-highest represented .S total cell count , yield and accumulation of pigments which compared
with tlie other treatments, which recorded maximum production during the period 4 - 6 days of experimental periods , also the growth parameters of Scenedesmus at 5000 Lux were increasing until
6 days followed by drop in Chlorophyll accumulation .
3-The results showed that growth parameters of Ch/orella at Continuous light treatment (24L\OD Light-dark cycle) was increasing yield , which recorded maximum production at 4 days of incubation periods compared with the other treatments, as well as there was Scenedesmus at the same treatment
,which recorded maximum production during the period of 4 days of culture age , it is also obvious
that these growth parameters recorded their highest at I 0 L\ 14 D treatment at the end of incubation periods ( 8 days ) represented as total cell count , weight gain and pigments content. this phenomenon could be explained highly at 12LI 120 of 4 days , while that was accumulation of pigments increased intensified at 6 days .
4- The results showed that growth parameters of Clrlorel/a at treatment two T2 : B.B.M medium supplemented with BA at a concentration of 0.25 mg/L medium was increasing yield expressed as total cell count during the period 6 days of incubation periods compared with other treatments , also obvious that pigments accumulated rec0rded their highest values at the end of inculiation periods (8 days), while the growth parameters of examined algae was more intensive at treatment one T 1 :B.B.M medium supplemented with BA at a concentration of 0.5 mg/L which recorded maximum production during the period of 4 days .
5- The results showed that growth parameters of Clr/orella at four Lines was more highest represented as cell numbers , yield gain and Chlorophyll content compared with the other treatments, which recorded maximum production during the period of 6 days of incubation periods , but revealed drop in Carotenoids content , while growth Scenedesmus recorded maximum production at control treatment (one lines )of 6 days of culture age represented as total cell count. but also the yield and pigments accumulation which recorded highest values until the end of incubation periods ( 8 days ) .
