The morphology and bioactivity of the rice field cyanobacterium Leptolyngbya.
The genus Leptolyngbya comprises filamentous cyanobacteria that are important in rice fields. In the rhizosphere, cyanobacteria produce a variety of secondary metabolites such as auxins that are important in agriculture soil performance. To assess this, Leptolyngbya strain MMG-1, was isolated from the rhizosphere of rice plants and described. For this, the morphology of this strain was studied ...
متن کاملPhotokinesis of Cyanobacterium Synechocystis sp. PCC 6803
Motile cyanobacterium Synechocystis sp. PCC 6803 cells show photomovement with respect to the light stimulus. Under lateral irradiation, Synechocystis displays a phototactic gliding movement toward the light source by a twodimensional random biased walk. Under vertical irradiation, Synechocystis decreased the frequency of mean vectorial gliding speed dependent on the applied fluence rate, where...
متن کاملTasiamide, a cytotoxic peptide from the marine cyanobacterium Symploca sp.
The acyclic peptide tasiamide (1) has been isolated from the marine cyanobacterium Symploca sp. The planar structure and absolute stereochemistry of the peptide were deduced by 2D NMR techniques and chiral HPLC. Tasiamide (1) was cytotoxic against KB and LoVo cells with IC(50) values of 0.48 and 3.47 microg/mL, respectively.
متن کاملLyngbya Sp.: a Suitable Cyanobacterium for Harvesting Antimicrobial Compounds
Lyngbya spp. is one of the most efficient groups of secondary metabolite producers and is very important from pharmaceutical point of view. Among its various species, majuscula is the major producers of commercially important biomolecules. Several species have been isolated and screened from the marine in the past decades. Although the chance of isolating a novel Lyngbya strain from a marine ha...
متن کاملImpact of Azospirillum sp. B510 Inoculation on Rice-Associated Bacterial Communities in a Paddy Field
Rice seedlings were inoculated with Azospirillum sp. B510 and transplanted into a paddy field. Growth in terms of tiller numbers and shoot length was significantly increased by inoculation. Principal-coordinates analysis of rice bacterial communities using the 16S rRNA gene showed no overall change from B510 inoculation. However, the abundance of Veillonellaceae and Aurantimonas significantly i...
