Progressive depletion of oil and conventional fossil fuels, an increased energy demand and an increased struggle for national energy security has led to the development of alternative biobased fuels, bioethanol being one of them. Bioethanol can be made from many different raw materials, and based on this are classified as 1 generation and 2 generation. This research work dealt with 2 generation...

To the Editor : Molybdenum cofactor deficiency (MoCoD, MIM 252150) is an autosomal recessive and rare metabolic disease (1). Absence of the cofactor inactivates sulphite oxidase activity thereby resulting via elevated sulphite levels in severe and progressive neurological damage. Affected patients are found worldwide and usually come to clinical attention by intractable seizures with a prominen...

Microbial flora of portuguese chouriço (Alentejano (A) and Ribatejano (R)) with abnormal sensorial characteristics along shelf life was studied. Mesophilic anaerobic bacteria, enterococci, mesophilic sporeformers, coliforms, coagulase-positive staphylococci, sulphite reducing clostridia, Clostridium perfringens, moulds and yeasts were the most representative in both types of chouriço.

The colloid silver sols with defined average particle size were prepared by means of chemical reduction of silver compound [Ag(SO3)2] 3– by several organic redox systems used as development agents in photography. The average size of the particles varied from 700 to 150 nm in dependence on sulphite concentration in reaction system and reduction compound type.

Sulphate assimilation provides reduced sulphur for the synthesis of cysteine, methionine, and numerous other essential metabolites and secondary compounds. The key step in the pathway is the reduction of activated sulphate, adenosine 5'-phosphosulphate (APS), to sulphite catalysed by APS reductase (APR). In the present study, [(35)S]sulphur flux from external sulphate into glutathione (GSH) and...
