A new bioautographic assay suitable for the localisation of beta-glucosidase inhibitors present in a complex matrix is described. Enzyme activity was detected using esculin as the substrate to produce esculetin, which reacts with ferric ion to form a brown complex.

A metagenomic cosmid library was prepared in Escherichia coli from DNA extracted from the contents of rabbit cecum and screened for cellulase activities. Eleven independent clones expressing cellulase activities (four endo-beta-1,4-glucanases and seven beta-glucosidases) were isolated. Subcloning and sequencing analysis

Four different environmental DNA libraries were prepared from microbial consortium collected from forest soil, dung of elephant, cow rumen and rotted tree. Seven independent clones specifying cellulase activities (five endo-beta-1,4-glucanases and two beta-glucosidases) were isolated and identified. Sequence analysis of

Rutin and esculin have been polymerised by laccase. Five fractions with M(w)¯ between 2127.42 and 8331.85g/mol for oligorutins, and between 688.12 and 6973g/mol for oligoesculins, were obtained. Fourier transformed infrared analysis showed that oligorutins were formed through C-C, C-O and

The aim of this work was to study the microbiological, physico-chemical and proteolytic changes in Valdeón blue-veined cheese during ripening. Eight replicas of cheese were produced and a total of 48 cheeses were analysed. Lactic acid bacteria, mainly lactococci, were
