Primary urban wastewater was processed using the microalga Scenedesmus sp. in an outdoor pilot-scale raceway reactor connected to ultrafiltration membrane. The goal separate cellular retention time from hydraulic time. This strategy led a 129.3% increase daily volume of treated per square meter, and 48.7% biomass productivity final value 22.2 ± 1.9 g·m−2·day−1. Nutrient removal highly influence...

Biofuels from micro-organisms represents a possible response to the carbon dioxide mitigation. One open problem is improve their productivity, in terms of biofuels production. To do so, an improvement present model growth and production required. However, this implies understanding spontaneous conditions bacteria. In paper, thermodynamic approach developed order highlight fundamental role elect...

Lacticin Q, a lactococcal pore-forming bacteriocin, shows activity toward Gram-positive bacteria but not Gram-negative bacteria. Lacticin Q did not induce permeability of the outer membrane of Gram-negative bacteria. Experiments using model membranes containing outer membrane components suggested that lacticin Q binds to the outer membrane of Gram-negative bacteria but is unable to penetrate it...
