The greatest concern in dairy farming nowadays is bovine mastitis (BM), which results mainly from bacterial colonization of the mammary gland. Antibiotics are the most widely used strategy for its prevention and treatment, but overuse has led to grow

PAH removal by immobilized bacterial cells-support systems using low-cost culture media for biomass production

Autor: Marcela Alejandra Ferrero, María Silvina Juárez Tomás, Mauricio Alessandrello, Paula Isaac, Diana L. Vullo

Publikováno v: International Biodeterioration & Biodegradation. 120:6-14

The use of immobilized biomass for polycyclic aromatic hydrocarbon (PAH) removal from a liquid phase is a very promising technology. For this technology to be economically viable, the biomass production and immobilization should be as cost-effective

The main cause of mastitis, one of the most costly diseases in the dairy industry, is bacterial intramammary infection. Many of these bacteria are biofilm formers. Biofilms have been associated with resistance to antibiotics and to the host immune sy

Chitosan nanoparticles enhance the antibacterial activity of the native polymer against bovine mastitis pathogens

Autor: Paula Isaac, Maria Laura Breser, María Soledad Orellano, Carina Porporatto, Luciana Paola Bohl, Ruben Dario Falcone, Agustín Conesa

Publikováno v: Carbohydrate polymers. 213

Staphylococcus is the most commonly isolated genus from animals with intramammary infections, and mastitis is the most prevalent disease that affects dairy cows in many countries. These pathogens can live in biofilms, a self-produced matrix, which al

Publikováno v: International Biodeterioration & Biodegradation. 105:1-6

A combination of RT-PCR assays and of Northern blots were used to evaluate the ability of naphthalene, phenanthrene and pyrene to induce nahAc from three Pseudomonas isolates obtained from oil-contaminated marine sediments. Naphthalene dioxygenase ac

Pre-exposition to polycyclic aromatic hydrocarbons (PAHs) enhance biofilm formation and hydrocarbon removal by native multi-species consortium

Autor: Alexandre José Macedo, Mauricio Alessandrello, María Cristina Estévez, Marcela Alejandra Ferrero, Paula Isaac

In this work, a biofilm-mediated removal of polyaromatic hydrocarbons (PAHs) was proposed. PAHs are toxic and persistent contaminants from petroleum industry, dispersed on water, soils, air and sediments. The removal capabilities of C15 mixed culture
