the objective of this research was to study the feasibility of a two stage continuous system employing anaerobic-aerobic microbial film for domestic wastewater treatment and the effect of iron on the behavior of sulfate reducing bacteria in anaerobic metabolism. a bench scale system with an anaerobic filter followed by aerobic fixed units used plastic media and was operated in up flow manner wi...

in recent years, there has been an increasing interest in using food additives from natural sources to improve taste and also extend the shelf-life of semi-preserved foodstuffs. the aim of this study was to examine the chemical and microbiological changes promoted by a local marinating process in rainbow trout fillets during chilled storage. fish fillets were immersed in marinades and stored at...

introduction: p. aeruginosa is an important multi-drug resistant (mdr) opportunistic pathogen in hospital-acquired infections. several methods based on dna analysis have been used for investigating genetic diversity of p. aeruginosa isolates. among them, rep‑pcr typing has been introduced as a rapid, low cost method with high discriminatory power. the aims of this study were to investigate geno...

zero tillage practices have a direct effect on soil microbial communities modifying soil productivity and sustainability. the crop sequences used can change the aforementioned properties, too. in this study, we evaluated the effect of crop sequences under zero tillage management on soil biological and chemical properties including vertical distribution of soil organic carbon, soil basal respira...

concurrent renewable energy production and wastewater treatment are two main reasons for using microbial fuel cells (mfcs). in this study, real wastewater was used for treating and power generation by air cathode microbial desalination cells (acmfc). the total duration of voltage generation by acmfc was about 151.9 ±23.2 h. the maximum voltage produced from municipal wastewater treatment was 27...

background and objectives: bacterial vaginosis (bv) is a common disorder which happens when the balance of bacterial flora in vagina is disrupted by a shift in concentration of lactobacillus and pathogenic bacteria. it has significant sequelae including increased rates of late miscarriage when diagnosed in early pregnancy, premature rupture of the membranes, endometritis, preterm labour and del...

abstract in this study, fresh pistachio of 'ohadi' and 'akbari' cultivars expose to the uv-c radiation with a wavelength of 0, 3, 6 and 12 kj/m2, then located at temperature of 1 ± 3 degrees celsius for 45 days. properties or attributes, including weight loss, stiffness and sensory evaluation of fresh pistachio after 20 and 45 days storage were measured. results showed that pistachio nut weight...

introduction: preventing and starting early treatment of infections in patients whose immunity system is weak due to malignancies like leukemia can reduce mortality. this study aimed to determine microbial and antibiotic resistance patterns in clinical samples of patients with acute leukemia to start early treatment before the results of clinical tests are known. subjects and methods: in this c...

the general objective of this study was to develop a highly efficient, economical andintegrated technology for the removal of nitrogen compounds through denitrification via nitrite. toachieve this, a modified uasb reactor was designed, set-up and operated using chilean zeolite asmicrobial support. the results were compared to a conventional uasb reactor used as control. thevolume of each reacto...

a fundamental shift to a total system approach for crop management in greenhouses is urgently needed to resolve escalating economic and environmental consequences of long-lasting undesired effects of synthetic pesticides used in combating agricultural pests. the aim of this study was to examine a potential new approach i.e. microbial-based production system (mps) for greenhouse-grown peppers. f...
