Exploring the Bio-efficacies of Methanolic Extracts of Nostoc muscorum and Calothrix brevissima with their Characterization Using GC-MS

Biomedical potential of Anabaena variabilis NCCU-441 based Selenium nanoparticles and their comparison with commercial nanoparticles

“…Compounds of other classes like alkane (Heptane, 3,3-dimethyl), alkene (Neophytadiene), cycloalkene derivatives (1,3-cyclohexadiene, 5-(1,5-dimethyl-4-hexenyl and 3-methyl-5-(2,6,6-trimethyl-1-cyclohexen-1-YL)-), phenol (Phenol, 3,5-bis(1,1-dimethylethyl) and ether (1,3-Propanediol, decyl ethyl ether) have been also obtained in the present study using Anabaena variabilis NCCU-441 extract. Previous study have also reported some related compounds like Heptane, 2,5,5-trimethyl-, a derivative of Heptane, 3,3-dimethyl from Nostoc muscorum NCCU-442 45 , Neophytadiene from Plectranthus amboinicus 46 , 1,3-cyclohexadiene, 5-(1,5-dimethyl-4-hexenyl from Zingiber officinal 47 , Phenol, 3,5-bis(1,1-dimethylethyl from Calothrix brevisimma 43 , 2 4 –Dimethylheptane, a derivative of 3,3-Dimethylheptane from Pulicaria undulata 48 , 1,3-Propanediol-2-ethyl-2-hydroxymethyl, a derivative of 1,3-Propanediol, decyl ethyl ether from Lycium chinense Miller fruits 49 were also reported with good reducing ability. Thus, all these compounds from cyanobacterial extract are the probable reducing agents that reduce sodium selenite to B-SeNPs.…”

“…1, 2-Benzenedicarboxylic acid and 2-(3-acetoxy-4, 4, 10, 13, 14-pentamethyl-) were also observed but in lesser amount. Some researchers have also reported the presence of these two carboxylic acids and reducing nature of cyanobacteria- Calothrix brevisima 43 and angiosperm- Punica species 44 .…”

Toxicological assessment of Phormidium sp. derived copper oxide nanoparticles for its biomedical and environmental applications

“…Methacrylic acid (0.13%) and 1, 2-benzenedicarboxylic acid (0.22%) were also identified in extract. Previously, the reducing nature of these two carboxylic acids was reported in Calothrix brevisima 30 and Punica species 31 . Compounds of other classes like alkane (Nonadecane), alkene (Neophytadiene, 1, 3, 12-Nonadecatriene), cycloalkene derivatives (cyclododecyne, tricycle [20.8.0.0(7,16)] triacontan and 1,1':3',1"-tercyclopentane, 2'-dodecyl), derivative of acetanilide (acetamide, N-(3,5-diaminophenyl) and phenol (Phytol) have been also obtained in the present study using Phormidium sp.…”

“…cell extract. During previous studies some related compounds were also reported with good reducing ability like, Neophytadiene from Plectranthus amboinicus 32 , 5-(1,5-dimethyl-4-hexenyl from Zingiber officinal 33 , Phenol, 3,5-bis(1,1-dimethylethyl from Calothrix brevisimma 30 . The phyto-chemicals present in cyanobacterial extract such as chlorophyll, carotenoids, phycobilliproteins, flavonoids, phenols and proteins act as both reducing as well as stabilizing (capping) agents for NPs synthesis 34 .…”
