TL;DR: In this article, the authors synthesize, in a simple and green way, via the Tollens method, silver nanoparticles (AgNPs), using as a stabilizer the biosurfactant produced by Bacillus cereus UCP 1615 cultivated in a low-cost medium, with waste frying oil as a substrate.

TL;DR: For saturation of the treated water with atmospheric air in a dissolved air flotation (DAF) system and production of microbubbles, the air was introduced through the suction pipe of a centrifugal pump as discussed by the authors.

TL;DR: In this article, the authors evaluated the surfactant properties of the Artocarpus heterophyllus plant extract and its application in oil removal of solid surface and showed that this surfactants of vegetable origin obtained from fruit extract exhibited a low toxicity (germination index with values of 100 at 98 %) of biosurfactant and the efficient oil removal on a solid surface between 82.6 ± 0.5 a 78.872 cm2 the motor oil.

TL;DR: Biosurfactant Application as Alternative Collectors in Dissolved Air Flotation System and its Applications in Pernambuco and Recife and the Northeast Biotechnology Network.

TL;DR: In this paper, the authors used sugar cane molasses as an alternative substrate for bacterial cellulose (BC) production on an industrial scale, and found that the best cost and yield was reached by the alternative medium formulated with 15 g/L of rawhide molasses (sample B), 5 g/ l glucose, 1.5 g/l acid citric and 2.7 g/ L Na2HPO4, without any nitrogen source addition (medium 3), which demonstrated 52, 59 and 65% in dry, hydrated mass and yield, respectively, when compared
