TL;DR: Green microalgae evaluated for their ability to support carbon, nitrogen and phosphorous removal in symbiosis with activated sludge bacteria during the biodegradation of four and eight times diluted piggery wastewater in batch tests showed that microalgal tolerance towards NH(3) was hypothesized as the key selection criterion.

TL;DR: Two conventional chemical coagulants and five commercial polymeric flocculants were comparatively evaluated for their ability to remove algal-bacterial biomass from the effluent of a photosynthetically oxygenated piggery wastewater biodegradation process.

TL;DR: The 16S rDNA gene sequence analysis showed 99% similarity between strain LV01 and Bacillus pumilus (embAJ494727) and its display maximum activity values at pH 9, 30°C y 1.7M NaCl , thus exhibiting remarkably haloalkalitolerant properties.

TL;DR: During a biological survey carried out in five shallow, high-altitude saline lakes of the Bolivian Altiplano in 2009, six unknown diatom taxa were found in various lake populations, allowing the description of the following new taxa.

TL;DR: Enzyme production in liquid medium identified strain LB-4 as the best enzyme producer with 10 U/ml xylanolytic activity and showed 99% similarity between strainLB-4 and Bacillus pumilus (embAJ494727).
