Morphological variability survey of cyanobacterium Anabaena sp. ISC55 in liquid mixotrophe treatment
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2014, Vol 5, Issue 2
Abstract
The variety of phenotypes of cyanobacteria is accompanied by morphological plasticity changing accordingly to different environmental or culture conditions. In this research, the effect of different treatments of liquid mixotrophe on morphological responses, structural changes and biometrical of Anabaena sp. ISC55 were studied. This investigation was performed in time periods of weekly and daily. Due to the morphological variability of cyanobacteria in different conditions, molecular and genetics studies should be performed for identify of this cyanobacterium. In this study identification of Anabaena sp. ISC55 was performed based on diacritical morphological such as cell shape, cell size, presence or absence of sheath and 16S rRNA gene sequencing. The results indicated that shape and size of vegetative cells and heterocytes in this species have changed in different treatments of liquid mixotrophe compared with control treatment; also this species in glucose treatment has produced more biomass.
