A Rapid Plate Screening Technique for Extracellular Ribonuclease Producing Strains
نویسندگان
چکیده
A plate assay is described to detect extracellular RNase producing strains. RNA is used in the Petri dish assay for the determination of RNase activity. After growth of the organisms, the agar plate is flooded with a RNA precipitant and enzyme activity is shown by clear zones (halos) around the colonies. The simultaneous use of specific RNase inhibitor like diethyl pyrocarbonate allow the specificity of enzyme to be determined. Besides the efficiency of this technique has also been tested to select mutants during strain improvement.

A Rapid and Efficient Dye Based Plate Assay Technique for Screening of L-Asparaginase Producing Fungal Strains
L-Asparaginase enzyme has received great attention owing to its potential as anticancer drug and food processing agent. L-Asparaginase producing microbes are conventionally screened on phenol red plates containing L-asparagine as the sole nitrogen source for its growth. However, the contrast of the zone in phenol red plates is not very distinct. To overcome this problem, an alternate methodolog...

متن کاملCellobiose Dehydrogenase Production by the Genus Cladosporium
Cellobiose dehydrogenase (CDH EC.1.1.5.1) is an extracellular enzyme that mainly produced by wood-degrading fungi. It oxidizes cellobiose to cellobionolactone using a wide spectrum of electron acceptors. The key roles of CDH in growth, metabolism, and some other important cellular processes such as cellulose degradation in fungi have been noted. Since the demands for finding new sources of CDH ...
متن کاملDirectional Breeding of High Itaconic Acid Yielding Strain of Aspergillus terreus with a New Plate Technique
Itaconic acid is commercially produced by the cultivation of Aspergillus terreus using starch hydrolysate as carbon source. The degree of hydrolysis had a great influence on itaconic acid production which was suitable when corn starch was saccharified at 35 DE. The α-amylase was sufficient to drive the starch hydrolysis to the degree. The agar plate assay with LiCl treatment provided a rapid, s...
