Application
Esculin hydrate may be used as an analytical standard for:
- The detection of glucosidase inhibitors by thin-layer chromatography (TLC) bioautographic method.
- Library screening in the characterization of novel cellulase genes from uncultured microorganisms.
- Evaluation of mutagenic and antimutagenic activities of oligorutin and oligoesculin.
- Detecting β-glucosidase activity in the identification of novel cellulase genes from uncultured microorganisms in rabbit cecum.

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

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.

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
