Analysis of autocatalytic reactions with michaelis-menten kinetics in an isothermal continuous stirred tank reactor
(1997)A systematic analysis of the behavior of autocatalytic reactions obeying Michaelis-Menten kinetics and taking place in an isothermal continuous stirred tank reactor is presented. The mathematical model is solved for general ... -
Aquatic toxicity from pulp and paper mill effluents:a review
(2001)Effluents from pulp and paper mills are highly toxic and are a major source of aquatic pollution. More than 250 chemicals have been identified in effluents which are produced at different stages of papermaking. Their toxic ... -
Artificial in vivo antigen presentation by the APCs and subsequent T-cell activation: a feasibility analysis
(2002)Inappropriate antigen presentation by the antigenpresenting cells (APCs) is a cause of various diseases. One of the ways to combat these diseases is to immobilize the APCs near the infected tissue or a tissue which is ... -
Biodesulphurization of coal: effect of pulse feeding and leachate recycle
(2001)Biodesulphurization of coal was carried out under four modes of operation namely: conventional batch, constant volume pulse feeding (CVPF), increasing volume pulse feeding (IVPF) and leachate recycle. The effects of different ... -
Biodesulphurization of Indian (Assam) coal using thiobacillus ferrooxidans (ATCC 13984)
(2000)The pyritic sulphur removal from coal and pyrite by Thiobacillus ferrooxidans was studied in a batch reactor. Microbial oxidation of ferrous iron to the ferric form, the central step in the biodesulphurization process was ... -
Biosynthesis of tannase and hydrolysis of tannins to gallic acid by aspergillus awamori — optimisation of process parameters
(2000)Tannin acyl hydrolase (tannase) is an industrially important enzyme produced by a large number of fungi. Tannic acid concentration, agitation speed and pH during the fermentation were identified as important process ... -
Biosynthesis of xylanolytic and xylan-debranching enzymes in Melanocarpus albomyces IIS 68
(1997)Melanocarpus albomyces IIS 68 synthesizes xylanase, ,&xylosidase and xylan debranching enzymes, namely, acetyl esterase, a+arabinofuranosidase and a-o-giucuronidase, when grown on various substrates. All five enzymes were ... -
