Due to the steadily rising number of students and simultaneous reduction in practical lessons study programs, need for alternative learning resources is increasing. In this work, a method described which allows real laboratory equipment be represented as web-based models, using stirred bioreactor an example. The model that was developed explore design operation bioreactors independently time, l...

Optimization of a fixed-bed bioreactor used in wastewater treatment is addressed. The objective of optimization is to maximize the treatment efficiency of the biofilter by manipulating the feed flow rate while satisfying operational constraints. Numerical results indicate that the optimal input is characterized as being on the boundary of the admissible region. Thus, the characterized optimal s...

In this study, a low-cost RGB sensor is developed to measure online the microalgae concentration within a photo-bioreactor. Two commercially available devices, i.e., a spectrophotometer for offline measurements and an immersed probe for online measurements, are used for calibration and comparison purposes. Furthermore, the potential of such a sensor for estimating other variables is illustrated...

This review attempts to provide an updated compilation of studies reported in the literature pertaining to reactors containing lipases in immobilized forms, in a way that helps the reader direct a bibliographic search and develop an integrated perspective of the subject. Highlights are given to industrial applications of lipases (including control and economic considerations), as well as to met...

Various strategies have been developed to exploit plants as bioreactors for the production of pharmaceutical antibodies, to engineer antibody-mediated pathogen resistance or to alter the plant phenotype by immunomodulation. Recent research developments focus on the fine-tuning of expression systems and the detailed characterisation of recombinant products, including the implications of plant-sp...

BACKGROUND Phthalic acid esters, including diethyl phthalate (DEP), which are considered as top-priority and hazardous pollutants, have received significant attention over the last decades. It is vital for industries to select the best treatment technology, especially when the DEP concentration in wastewater is high. Meanwhile, anaerobic biofilm-based reactors are considered as a promising opti...

Tile drainage is the major source of nitrate in the upper Midwest, and end-of-tile removal techniques such as wood chip bioreactors have been installed that allow current farming practices to continue, with nitrate removed through denitrification. There have been few multiyear studies of bioreactors examining controls on nitrate removal rates. We evaluated the nitrate removal performance of two...

Abstract Organic waste from agricultural production, bedding manure of cattle, pigs, sheep, horses, chickens and poultry litter when kept in cages are the main components for production organic fertilizers biogas production. Waste grain, cereal crops sugar beets should be used as reducing moisture during aeration piles, houses bioreactors. Fresh stored on sites where, before being processed bio...
