Microalgae culture is a potential source of biodiesel and one of the best alternatives as raw material for biodiesel production. The first objective of this work is the pilot plant design for microalgae culture of high oil content species. The design was inspired by raceway large-scale culture. Although this kind of culture is usually in outdoor ponds, the pilot plant is an indoor raceway pond,...

■ Abstract This paper examines the role of culture as a factor in enhancing the effectiveness of health communication. We describe culture and how it may be applied in audience segmentation and introduce a model of health communication planning— McGuire’s communication/persuasion model—as a framework for considering the ways in which culture may influence health communication effectiveness. For...

Crude glycerol is the major byproduct of the biodiesel industry. There is an abundance of this byproduct and purifying it for use in industries such as food, pharmaceutical, or cosmetic is prohibitively expensive. Developing an alternative use for crude glycerol is needed. Utilizing it as a carbon source in the fermentation of algae is one potential method for using this underutilized byproduct...

This paper presents a pumpless cell culture chip, where a constant-rate medium perfusion is achieved by balanced droplet dispensing. Previous pumpless cell culture chips, where the gravity-driven flow is induced by gradually decreasing the hydraulic-head difference, Δh, between source and drain reservoirs, result in a decreasing perfusion-rate. However, the present pumpless cell culture chip, w...

low grade grape juice concentrate was used as carbon source for xanthan production. significant factors affecting xanthan concentration, productivity and viscosity were investigated using plackett-burman design. based on the obtained results, carbon and nitrogen concentrations, inoculum size and agitation rate, were assumed as significant factors. broth culture viscosity and xanthan concentrati...

stem cells located at the limbus ,  are the ultimate source for regeneration of the corneal epithelium in the normal and traumatized states.  when limbal stem cells are dysfunctional or deficient, limbal stem cell deficiency (lscd) develops. its surgical management depends on laterality and severity of corneal-limbal involvement. conventional methods of stem cell transplantation are conjunctiva...

We have isolated a mixed bacterial culture (BC-1) which is capable of degrading the gasoline oxygenate methyl t-butyl ether (MTBE). BC-1 was developed from seed microorganisms present in a chemical plant biotreater sludge. This enrichment culture has been maintained in continuous culture treating high concentrations of MTBE (120 to 200 mg/liter) as the sole carbon source in a simple feed contai...

MATSUYA, Y. and YAMANE, I. Culture Conditions Necessary to Sustain the Serial Culture of Lung Cells of Newborn Hamster in Albumin Fortified Medium. Tohoku J. exp. Med., 1970, 101(4), 387-396•\Using various albumin fortified medium, many neonatal hamster lung cells were developed into established lines. The optimal culture condition to evolve into cell lines was investigated by varying the sourc...

Subsequent to this, 34 laboratories across England and one from Northern Ireland have reported identification of 77 Paecilomyces variotii isolates from normally sterile sites, nearly all from blood culture, to the HPA. The HPA Mycology Reference Laboratory (MRL) would usually receive only 5 or 6 P. variotii isolates per year. No source for the suspected contamination has yet been identified. Di...
