Sustainable supply of food and energy without posing any threat to environment is the current demand our society in view continuous increase global human population depletion natural resources energy. Cyanobacteria have recently emerged as potential candidates who can fulfil abovementioned needs due their ability efficiently harvest solar convert it into biomass by simple utilization CO2, water nutrients. During conversion radiant chemical energy, these biological systems produce oxygen a...
In the present study we have made an attempt to develop eco-friendly, cheap and convenient biological (green) method for synthesis of silver nanoparticles (AgNPs) using cell extract cyanobacterium Nostoc sp.strain HKAR-2.Their anticancerous, antifungal antibacterial properties were also studied against MCF-7 cells, two fungal strains (Aspergillus niger Trichoderma harzianum) plant bacterial (Ralstonia solanacearum Xanthomonas campestris), respectively.The structural, morphological optical...
Reactive oxygen species (ROS) are cell signaling molecules synthesized inside the cells as a response to routine metabolic processes.In stress conditions such ultraviolet radiation (UVR), ROS concentration increases several folds in that become toxic for survival.Here we present method vivo detection of by using an oxidant-sensing probe 2',7'-dichlorodihydrofluorescein diacetate (DCFH-DA) cyanobacteria.This provides reliable, simple, rapid and cost effective means cyanobacteria.
Population of the Earth has been projected to reach ~9.7 billion by 2050 and Asia Africa would be major contributors this enhanced population. This increased population is directly related with higher demand food security in very near future. Modern agricultural management heavily dependent on fertilizers for crop production, but increasing use chemical-based inorganic may a serious threat environment human health. Microalgae have biostimulant biofertilizer properties which are attracting...
In the present investigation, biological crusts from surface of eight historical monuments Varanasi, India, were examined for presence scytonemin (a cyanobacterial photoprotective pigment) containing species. Lyngbya sp. and Scytonema dominant cyanobacteria in all crust samples. The absorption spectroscopic data chlorophyll, carotenoids showed that was more abundant than carotene chlorophyll crusts. Identification these compounds done using UV-Vis spectroscopy High Performance Liquid...
Macroalgae have evolved different strategies to mitigate the damaging effects of solar ultraviolet radiation (UVR), including accumulation photoprotective compounds such as mycosporine-like amino acids (MAAs). MAAs are secondary metabolites, synthesized by a large variety organisms macroalgae, phytoplanktons, cyanobacteria, lichen, fungi and some marine animals. act photoprotectants antioxidants. In present investigation, profile methanolic extracts two red algae Gelidium sp. Ceramium sp.,...
In the present study silver nanoparticles (AgNPs) have been synthesized through cell-free extracts of rooftop dwelling cyanobacterium Scytonema geitleri HKAR-12. UV-VIS spectroscopy, FTIR, X-ray diffraction, SEM and TEM were used for determination morphological, structural optical properties AgNPs. Extracts HKAR-12 ability to reduce AgNO3 Ag0. Sharp peak at 422 nm indicated rapid synthesis FTIR results showed presence different groups responsible reduction XRD pattern confirmed crystalline...
Background: Cyanobacteria are the predominant atmospheric nitrogen fixers of aquatic as well terrestrial ecosystems. Harvesting solar energy for photosynthesis exposes cyanobacteria simultaneously to lethal doses ultraviolet radiation (UVR) in their natural brightly light habitats. To counteract damaging effect UVR, synthesize novel secondary metabolites such mycosporine-like amino acids (MAAs) and scytonemin. By application “omics” techniques cyanobacterial molecular biology is benefitted...
