The present study describes cyanobacterial species composition and their dominance in biological crusts from barks of different trees, roof top of building and soil of agricultural field. An attempt was also made to explore the presence of photoprotective compounds such as mycosporine-like amino acids (MAAs) in the crust samples. Microscopic examin...

Prolonged exposure to harmful ultraviolet radiation (UVR) can induce many chronic or acute skin disorders in humans. To protect themselves, many people have started to apply cosmetic products containing UV-screening chemicals alone or together with physical sunblocks, mainly based on titanium–dioxide (TiO2) or zinc-oxide (ZnO2). However, it has now...

Microalgae are a diverse group of photosynthetic organisms that can be exploited for the production of different compounds, ranging from crude biomass and biofuels to high value-added biochemicals and synthetic proteins. Traditionally, algal biotechnology relies on bioprospecting to identify new highly productive strains and more recently, on forwa...

The present investigation is aimed to understand how a bloom-forming cyanobacterium Microcystis aeruginosa adapts to changing climatic conditions. The cyanobacterium was exposed to stresses of UV-B (2 Wm⁻²) radiation and temperature (45 °C) for desired time intervals. Results showed that both the stresses affect growth and photosynthetic efficiency...

In recent decades, a shift has been seen in the use of light-emitting diodes over incandescent lights and compact fluorescent lamps (CFL), which eventually led to an increase in wastes of electrical equipment (WEE), especially fluorescent lamps (FLs) and CFL light bulbs. These widely used CFL lights, and their wastes are good sources of rare earth...

Red mud is a by-product of the production of alumina from bauxite ore. However, less than 2% of red mud produced is currently utilized. Red mud contains a number of residual scarce metals including rare earth elements, some at a considerable concentration, so synchronous cultures of the red microalga Galdieria sulphuraria were tested for their abil...

High energy demand and water crisis are two major concern nowadays. Various alternative energy sources have been searched and suggested from the researchers around the world to address this apprehension. Microalgae biofuel have been considered as future fuel. However economic feasibility of biofuel production from microalgae is still challenging du...

The extremophilic unicellular red microalga Galdieria sulphuraria (Cyanidiophyceae) is able to grow autotrophically, or mixo-and heterotrophically with 1% glycerol as a carbon source. The alga divides by multiple fission into more than two cells within one cell cycle. The optimal conditions of light, temperature and pH (500 µmol photons m −2 s −1 ,...

Metagenomic approaches have provided a better understanding of microbial diversity and function across the terrestrial biome. Initial studies on soil metagenomics involved construction of libraries and sequencing of cloned genes to know the product encoded, but now a days direct sequence-based information plays an important role in functional profi...
