There are few surveys about morphological adaptation on cyanobacteria to monochromatic light. Also very limited studies were done on the evaluation of their behavior. In this research, the effect of monochromatic red light rays at treatment of liquid and solid of mixotrophe including 0.05 percent of soluble sugars (glucose, fructose and sucrose) on morphological responses, communities, structural changes, biometry and situation of trichome of Leptolyngbya sp. were studied. This investigation was carried out in weekly and daily periods of time. Also, molecular identification of partial sequence of 16S rRNA was determined. Morphological and biometrical study indicates that change in nutritional conditions and the quality of light could be the causes of this type of cellular changes. Due to the morphological variability of cyanobacteria in different conditions, molecular and genetics studies should be performed for identify, taxonomy and systematic of them.
