The inherent control flexibility implied by solid-state lighting – united with the rich details offered by sensor networks – prompts us to rethink lighting control. In this research, we propose several techniques for measuring work surface illuminance and ambient light using a sensor network. The primary goal of this research is to measure work surface illuminance without distraction to the use...

The applications of ‘Diode Pumped Solid State Lasers’ (DPSSL) have experienced a rapid development in a large number of activities from industrial, medical, space and defence. These new activities are made possible by development of new performance in “High Power Laser Diodes” (HPLD). Modulight’s HPLDs are used for pumping DPSSL. The main applications are material processing, medical therapy, m...

Aim: The aims of the present study were to screen different filamentous fungi for extracellular cellulases production and to optimize solid-state fermentation medium and culture conditions to enhance cellulases production. Study Design: Using agro-industrial waste as raw material for the production of cellulases by a hyper cellulase producing fungus and evaluating the influence of various param...

Jatropha cake (JC), a toxic residue derived from the extraction of the oil from Jatropha curcas seeds, can be used as a culture medium for solid-state fermentation (SSF). Through this process, it is possible to detoxify and add value to this solid residue through the production of enzymes of biotechnological interest. However, one of the major technological bottlenecks in SSF is the microbial g...

The aim of this work was to study the possibility of monitoring citric acid production from mussel processing wastes (MPW) by Aspergillus niger in solid-state culture (SSC) on an inert support. This was conducted by measuring CO2 and O2 concentration in exhaust gases, using an automatic sampler connected to a gas chromatograph and a data acquisition system. The procedure permitted information o...

A native isolate of Pleurotus ostreatus HP-1 (Genbank Accession No. EU420068) was found to have an excellent laccase producing ability. The extracellular laccase was purified to electrophoretic homogeneity from copper sulphate induced solid-state fermentation medium by ammonium sulphate precipitation and ion-exchange chromatography. The enzyme was determined to be monomeric protein with an appa...

The aim of this study was to use agro-industrial residues for the production of a halotolerant keratinolyticprotease by Actinobacterium sp. in solid-state fermentation. Among various agro-industrial residues that were evaluated, apple pomace supported maximum protease production (8400 U/g material). The optimum conditions required for enzyme production were a fermentation period of 72 h, 10% (w...

Gallic acid production in a batch bioreactor was evaluated using as catalytic material the mouldy polyurethane solids (MPS) obtained from a solid-state fermentation (SSF) bioprocess carried out for tannase production by Aspergillus niger GH1 on polyurethane foam powder (PUF) with 5 % (v/w) of tannic acid as inducer. Fungal biomass, tannic acid consumption and tannase production were kinetically...

This study is focussed on the possibility of producing a yeast culture with yellow wine lees as a substrate by solid-state fermentation (SSF). Results showed that a yeast count of 1.58 × 109 CFU/g was achieved by signal factor and orthogonal experiments. After fermentation, the starch content in the yeast culture reduced from 32.2% ± 0.5% to 7.5% ± 0.2%, and the contents of crude protein and pe...

Background and objectives: The seeds of Securigera securidaca (L.) Deg. & Dorf. (Fabaceae) are used as anti-diabetic remedy in Iranian folk medicine. The aim of the present study was to establish the callus and suspension culture of S. securidaca seeds for the first time and to determine the major secondary metabolites including cardiac glycosides and total ph...
