An algorithm for analysing probed partial digestion experiments

A partial digestion of DNA (e.g. cosmid. Lambda, YAC, chromosome) is performed and the lengths of thoses fragments which hybridize to a labeled probe are measured using gel electrophoresis. We give an efficient algorithm that takes as input this experimental data and proposes one or more candidate solutions. Each solution designates the location of each restriction site and specifies the endpoi...

Investigation on anaerobic co-digestion of vegetable tannery sludge and fleshing in laboratory scale experiments

In this work, the efficiency and the technical feasibility of the anaerobic digestion of vegetable tannery industry primary sludge (VTPS) was investigated. Tests were conducted under mesophilic conditions in three laboratory scale (150 L) reactors. The investigation included two different solids retention time (15 and 25 d) and the codigestion of VTPS plus fleshing. Results showed that an incre...

Modeling of Anaerobic Digestion of Complex Substrates

A structured mathematical model of anaerobic conversion of complex organic materials in non-ideally cyclic-batch reactors for biogas production has been developed. The  model is based on multiple-reaction stoichiometry (enzymatic hydrolysis, acidogenesis, acetogenesis and methanogenesis), microbial growth kinetics, conventional material balances in the liquid and gas phases for a cyclic-bat...
