    The present invention relates to polypeptides having cellobiohydrolase II activity and polynucleotides having a nucleotide sequence which encodes for the polypeptides. The invention also relates to nucleic acid constructs, vectors, and host cells comprising the nucleic acid constructs as well as methods for producing and using the : 吴文平, 莱恩兰格, 多米尼克A斯科夫伦德, 刘晔. Examples of such expression results include the following, in order of highest production: Hormoconis resinae glucoamylase P ( g/L), Melanocarpus albomyces laccase ( g/L), Acrophialophora nainiana XynVI ( g/L), and CBH I-Fab fusion antibody ( g/L).

      SUMMARY Thermophilic fungi are a small assemblage in mycota that have a minimum temperature of growth at or above 20°C and a maximum temperature of growth extending up to 60 to 62°C. As the only representatives of eukaryotic organisms that can grow at temperatures above 45°C, the thermophilic fungi are valuable experimental systems for investigations of mechanisms that allow Cited by: Agro-industrial Wastes as Feedstock for Enzyme Production: Apply and Exploit the Emerging and Valuable Use Options of Waste Biomass explores the current state-of-the-art bioprocesses in enzyme production using agro-industrial wastes with respect to their generation, current methods of disposal, the problems faced in terms of waste and regulation, and potential value-added protocols for these.

Characterization and heterologous production of a novel laccase from Melanocarpus albomyces by Laura-Leena Kiiskinen Download PDF EPUB FB2

The production levels reported for the expression of Melanocarpus albomyces laccase in T. reesei are the highest heterologous laccase expression levels reported so far, allowing the obtainment of mg l −1 in shake-flask cultures, mg l −1 in batch fermentations, and mg l −1 in fed-batch fermentation.

Actually, a series of. Characterization and kinetic properties of the purified Trematosphaeria mangrovei laccase laccase of Melanocarpus albomyces has a half-life time of 5 h [43].

Two laccase-encoding genes from the marine-derived fungus Pestalotiopsis sp. have been cloned in Aspergillus niger for heterologous production, and the recombinant enzymes have been characterized to study their physicochemical properties, their ability to decolorize textile dyes for potential biotechnological applications, and their activity in the presence of sea by: 2.

The highest reported yields for heterologous proteins expressed in T. reesei are those of foreign fungal proteins that have reached gram levels, up to g/l for the Melanocarpus albomyces cellulase Cel5A (Table ; Haakana et al., ).The second best yields come from heterologous proteins of bacterial origin nearing and exceeding a gram per liter (Table ; Paloheimo et al., Cited by: 6.

pastoris is a popular host for heterologous laccase production, although laccase yields by P. pastoris typically do not exceed 10 U/mL and often require a long production cycle (e.g., ≥10 day) [8,35,36], which might at least partially be accounted for by difficult expression of laccases in P.

by: 6. Therefore, heterologous production in ascomycete hosts is often the approach of choice, but there are still many challenges in producing these enzymes. Factors hampering heterologous expression of basidiomycete genes in ascomycetes include differences in the gene content such as in codon usage bias, and intron structure and by: 2.

Laccases, multicopper oxidoreductases, are mainly produced in white-rot fungi and are considered as ideal green catalysts in industrial and biotechnological applications.

However, the development of laccases is limited due to the slow growth of natural laccase producing strains and the low expression levels of laccases. In this study, we designed three regulation strategies for laccase gene.

Filamentous fungi are commonly used in the fermentation industry for the large-scale production of proteins – mainly industrial enzymes.

This chapter presents a number of methods that have been successfully applied in the screening for enzymes from extremophilic microorganisms and their communities.

Search Tips. Phrase Searching You can use double quotes to search for a series of words in a particular order. For example, "World war II" (with quotes) will give more precise results than World war II (without quotes).

Wildcard Searching If you want to search for multiple variations of a word, you can substitute a special symbol (called a "wildcard") for one or more letters. Côté, A., Shareck, F.
