Leptolyngbya
Leptolyngbya
Genus of cyanobacteria
Leptolyngbya is a genus of cyanobacteria belonging to the family Leptolyngbyaceae.[1]
The genus has cosmopolitan distribution.[1]
Due to the high carbon storage capacity and poly(3-hydroxybutyrate) (PHB) formation, Leptolyngbya sp. NIVA-CYA 255 is a promising candidate for PHB production. Further work will focus on upscaling to a technical scale and monitoring the formation by LipidGreen2-based fluorometry.[2]
Little is known about the storage lipid composition in the filamentous genus Leptolyngbya, which belongs to the order Synechococcales. Leptolyngbya sp. are present in a wide range of habitats, including freshwater, marine, and terrestrial locations, and extreme places, such as thermal springs. Recently, PHB was isolated from Leptolyngbya valderiana and characterized by FTIR. Rueda et al. described PHB formation in microbial consortia containing Leptolyngbya sp. with 5 wt% PHB . Further studies have demonstrated that Leptolyngbya possesses a balanced ratio of intracellular composition and high lipid content, and is therefore a suitable host for potential large-scale applications .[3]
A 2022 study first investigated PHB formation in Leptolyngbya sp. NIVA-CYA 255, isolated from egyptian soil. For this purpose, a three-stage cultivation process was carried out, consisting of an initial biomass growth phase and a two-stage product formation phase.[3]
