Remediation of aquaculture water using microorganisms like Bacillus species is a burgeoning trend for the sustainable development of aquaculture industries. In this work, a Bacillus amyloliquefaciens strain (namely B. amyloliquefaciens HN), isolated from activated sludge of a polluted river, was evaluated for its potential in water remediation using simulated aquaculture water. B. amyloliquefac...

background: irradiation of water by uv has been considered as an attractive alternative for disinfection because its low- im pact, pathogen killing capacity shows tremendous promise for meeting today’s drinking water regulatory requirements. this study has been performed with the objective of utilizing medium pressure lamp in the preliminary stage of municipal wa ter treatment, namely prior to ...

nitrite is responsible for some characteristics of cured meat products such as color, flavor and suppressing the outgrowth and production of toxin from clostridium botulinum. despite all of its desired properties, nitrite is responsible for the formation of carcinogenic n-nitrosamine. in this study, nitrite-free and low-nitrite meat curing systems were developed to eliminate or reduce nitrite f...

background and objectives: sodium nitrite and potassium nitrite have been traditionally used for inhibition of clostridium botulinum and also as an agent to stabilize the color of meat products; however, usage of these additives at high levels could lead to toxicity and cancer originating from the formation of nitrosamines. nowadays, application of natural preservatives in order to reduce the n...

background: the assessment of altered nitric oxide (no) availability is of potentially important diagnostic and prognostic significance. the present study is aimed to investigate the effect of l-arginine (as a natural no donor) supplementation on no metabolite in a rabbit model of hypercholesterolemia to find a reliable marker for endothelial no production. methods: white male rabbits (n = 30) ...

conclusions nitrosamine was formed with conventional potato baking methods with the most nitrosamine formation found on the surface fried samples. nitrites amount in baked potatoes decreased. generally, the amount of nitrosamine in baked potato samples was lower than acceptable limits. results fried samples that were measured by the gas chromatography method had the highest average levels of ni...

Ruminal methane production is among the main targets for greenhouse gas (GHG) mitigation for the animal agriculture industry. Many compounds have been evaluated for their efficacy to suppress enteric methane production by ruminal microorganisms. Of these, nitrate as an alternative hydrogen sink has been among the most promising, but it suffers from variability in efficacy for reasons that are n...

AIM Excess levels of free radicals such as nitric oxide (NO) and superoxide anion (O(2)(-)) are associated with the pathogenesis of endothelial cell dysfunction in diabetes mellitus. This study was designed to investigate the underlying causes of oxidative stress in coronary microvascular endothelial cells (CMECs) exposed to hyperglycaemia. METHODS CMECs were cultured under normal (5.5 mmol/l...
