Genetic modification of carbon catabolite repression

The cellulase and hemicellulase genes of the filamentous fungus trichoderma reesei have been shown to be under carbon catabolite repression mediated by the regulatory gene cre1 . in this study, strains were constructed in which the cre1 gene was either completely removed or replaced by a truncated mutant variant, cre1 - 1 , found previously in the rut-c30 mutant strain with enhanced enzyme ...

Production of dissolving

Hemicellulose degrading enzymes mainly xylanases have been used for selective removal of pentosans in preparing dissolving-grade pulp. these enzymes are produced by many bacteria and fungi viikari et al. 1993, 1994.in the earlier studies viikari et al. 1986, 1987, crude culture filtrates of hemicellulases produced by different microorganisms were used and most of the reports published are ...

Global and regional fluxes of carbon from land use

1 introduction. the annual flux of carbon to the atmosphere from land use and land cover change lulcc helps define the global carbon budget le qur et al., 2015b and provides insights into the potential for land management to remove carbon from the atmosphere houghton et al., 2015.although the net flux is only about 10 of anthropogenic carbon emissions currently van der werf et al ...

Lignin recovery from spent alkaline pulping liquors

2 however, as reported by wallmo 2008, the addition of sulfuric acid disrupts the mills na and s balance in the recovery cycle. hence, even though sulfuric acid is cheaper than carbon dioxide on a mass or molar basis, in reality, it can lead to significantly higher chemical costs for a lignin plant if used in black liquor acidification.

Perturbations in the carbon budget of the tropics

Ecosystems store carbon as macromolecules lignin, cellulose, starch, proteins in plants and soil for a variable period of time galbraith et al., 2013, subsequently releasing co 2 through plant, animal and microbial respiration, and fire. the combined efflux to the atmosphere is somewhat less than the uptake by gross photosynthesis.

A modular esterase from penicillium funiculosum

An esterase was isolated from cultures of the filamentous fungus penicillium funiculosum grown on sugar beet pulp as the sole carbon source. the enzyme ferulic acid esterase b, faeb was shown to be a cinnamoyl esterase ce, efficiently releasing hydroxycinnamic acids from synthetic ester substrates and plant cell walls, and bound strongly to microcrystalline cellulose.

Decolorization and detoxification of extraction

Rhizopus oryzae , a zygomycete, was found to decolorize, dechlorinate, and detoxify bleach plant effluent at lower cosubstrate concentrations than the basidiomycetes previously investigated. with glucose at 1 gliter, this fungus removed 92 to 95 of the color, 50 of the chemical oxygen demand, 72 of the adsorbable organic halide, and 37 of the extractable organic halide in 24 h at ...

Transcriptomic analysis reveals key factors in fruit ...

2ethylene promotes fruit ripening whereas 1-methylcyclopropene 1-mcp, a non-toxic antagonist of ethylene, delays fruit ripening via the inhibition of ethylene receptor. however, unsuitable 1-mcp treatment can cause fruit ripening disorders. in this study, we show that short-term 1-mcp treatment 400 nll 1, 2 h significantly delays papaya fruit ripening with normal ripening characteristics.
