Abstract:

Highlights Novel three-bed, cascading-inlet bioreactor treated agricultural drainage from a 249-ha catchment. Nitrate removal rates and load reduction efficiencies were similar to those of traditional single-field bioreactors. Sedimentation problems reduced bed life; a sediment sensing and exclusion system solved them. This scale provides opportunities for centralized management and nutrient reduction verification.

Abstract:

Denitrifying bioreactor technology, where a solid carbon source (woodchips) acts as a reactive medium to intercept agricultural tile drainage water, has been successfully used to convert N (NO3-) to di-nitrogen (N2) gas. Four replicated field-scale (24 m long x 3 m wide x 1 m deep), bioreactors were built and operated at the St. John’s Research and Development Centre and were successful at removing a notable amount of nitrate (N) from agricultural subsurface drainage water. The objective of this study was to investigate the internal flow dynamics of one of these field-scale bioreactors as a pr

Abstract. High-frequency bromide (Br-) sensors could resolve challenges during denitrifying bioreactor tracer tests. Deployment of a Br- sensor during a tracer test resulted in both under- and over-reported concentrations. Collecting high-resolution Br- concentrations generally did not add value to calculated tracer metrics. However, high-frequency Br- sensors were overall considered a convenient tool, in part, due to ease of deployment. Bromide (Br-) tracer tests are an important environmental monitoring method for assessing internal hydraulics in denitrifying woodchip bioreactors. The object

Abstract:

In vitro long-term toxicity testing is becoming an important issue in the field of toxicology, and there is a need to develop new model systems that mimic human chronic exposure and its effects. The aim of this work was to test two long-term in vitro toxicity systems which are available, a flow-cell bioreactor (Tecnomouse) and a static cell bioreactor system (CELLine CL 6-well), and to compare them with the use of conventional cell culture flasks. A human cell line, Int 407, was exposed to cadmium chloride (CdCl2; 10–7–10–8M) for 4 weeks. Cell numbers and cell viabilities were determined by th

Abstract:

The enhancement of the production of lipopeptide biosurfactant by Bacillus pumilus 2IR as an oil field-isolated bacterium was investigated in the fed-batch fermentation using a 5-L bioreactor. The initial study on the culture medium composition used for biosurfactant synthesis revealed that biosurfactant production was greatly affected by glucose, crude oil, potassium nitrate and ammonium sulfate as pivotal carbon and nitrogen sources which were utilized for biosurfactant synthesis in the bioreactor. The results obtained from the batch fermentation process in the bioreactor showed that the qua

Abstract:

Somatic embryogenesis (SE) is an excellent example of mass plant propagation. Due to its genetic variability and low somaclonal variation, coffee SE has become a model for in vitro propagation of woody species, as well as for large-scale production of vigorous plants that are advantageous to modern agriculture. The success of the large-scale propagation of an embryogenic system is dependent on the development, optimization, and transfer of complementary system technologies. In this study, two successful SE systems were combined with a SETIS™ bioreactor immersion system to develop an efficient
