Automated filter paper assay determination cellulase activity

This study focused on determining the biochemical function of one of these putative cellulase-encoding genes, sco To our knowledge, this is the first report of a cellulolytic enzyme in S. Streptomyces coelicolor A3 2S. All other chemicals were purchased from Sigma Chemical Co.

Automated filter paper assay determination cellulase activity

Full citation Abstract Eight isolates of cellulose-degrading bacteria CDB were isolated from four different invertebrates termite, snail, caterpillar, and bookworm by enriching the basal culture medium with filter paper as substrate for cellulose degradation.

To indicate the cellulase activity of the organisms, diameter of clear zone around the colony and hydrolytic value on cellulose Congo Red agar media were measured. CDB 8 and CDB 10 exhibited the maximum zone of clearance around the colony with diameter of 45 and 50 mm and with the hydrolytic value of 9 and 9.

The extracellular cellulase activities ranged from 0. All the cultures were also further tested for their capacity to degrade filter paper by gravimetric method. The maximum filter paper degradation percentage was estimated to be Selected bacterial isolates CDB 2, 7, 8, and 10 were co-cultured with Saccharomyces cerevisiae for simultaneous saccharification and fermentation.

Ethanol production was positively tested after five days of incubation with acidified potassium dichromate Topics:Determination of Cellulase enzyme assay: substrate was done using the Miller’s modified method of DNSA.

1 unit of cellulase activity was defined as the filter paper in grams Wet weight in grams Dry weight in grams Wt.

In this review article, total cellulase activity by application of filter paper (filter paper assay, FPA) will be explained and then individual cellulase activities including EGs, exoglucanases, and β-glucosidases will be discussed.

This procedure is only appropriate for the determination of FPU activity in a cellulase preparation as defined by the IUPAC procedure as outlined above. 3.

Briefly, the methods are similar to the CMCase assay method, but the substrate used was Whatman No.

The. Use of DNS reagent for the determination of reducing sugars is not only a widely practised method,,, but, it is also an assay recommended by the International Union of Pure and Applied Chemistry (IUPAC); It is also an integral part of the filter paper assay which is another recommended assay by the IUPAC for the measurement of cellulase.

The final cellulase activity measured by the filter paper activity assay was around – filter paper units (FPU) mL −1 for all cultures, the culture with glycerol reaching slightly higher values (Fig.
