ABSTRACT In the current study, 18 halotolerant and halophilic bacteria have been investigated for their plant growth promoting abilities in vitro and in a hydroponic culture. The bacterial strains have been investigated for ammonia, indole-3-acetic acid and 1-aminocyclopropane-1-carboxylate-deaminase pro...

Background: Industrial wastewaters with a high content of nitrogen are a relevant environmental problem. Currently, treatments to remove nitrogen are not efficient, so is necessary to develop alternative methods. The objective of this study is to investigate a consortium of microalgae - nitrifying, that ...
Introdução - A amônia (NH3) é um poluente atmosférico cuja emissão é em parte provocada por atividades antrópicas. A geração de energia através da queima de combustíveis é uma dessas atividades, dentro da qual, o setor de transporte e principalmente os veículos automotores rodoviários são...
Ammonia (NH3) is an irritant and corrosive gas whose inhalation at high concentrations mainly occurs during agricultural and industrial activities, as occupational accidents. The extent and severity of the damage depends on the concentration and time of exposure to the toxic, which can cause skin, eye, r...
This study determined whether high levels of total ammonia nitrogen (TAN) as NH4+ are harmful to the growth performance of Nile tilapia juveniles. Fingerlings (0.31 ± 0.04 g) were assigned to 30 polyethylene 100-L tanks in a roofed room for 12 rearing weeks. There were increasing levels of TAN by increa...
Background: Constructed wetlands are a promising, cheap and effective wastewater treatment in small communities. The studies on these systems have been reported mainly from cold, tropical or subtropical climate regions. In this work we constructed a pilot plant with six horizontal subsurface flow constru...

A encefalopatia hepática (EH) é um distúrbio funcional do sistema nervoso central (SNC) associado à insufi ciência hepática, de fisiopatologia multifatorial e complexa. Devido aos avanços no conhecimento sobre o manejo da EH na cirrose e na insuficiência hepática aguda (IHA), a diretoria da Soci...
The effects of various levels of oxygen saturation and ammonia concentration on NTPDase (ecto-nucleoside triphosphate diphosphohydrolase, E.C. 3.6.1.5) and acetylcholinesterase (AChE, E.C. 3.1.1.7) activities in whole brain of teleost fish (Rhamdia quelen) were investigated. The fish were exposed to one ...
Através de exames físico-químicos e organolépticos, avaliou-se o estado de conservação de carne bovina moída, preparada industrialmente e embalada a vácuo, quando mantida a temperatura de 8°C, após a abertura da embalagem. As análises foram realizadas nos 1°, 3°, 5° e 7° dias de armazenage...
