The effect of abscisic acid on cotton (Gossypium hirsutum L. cv. Acala 4-42) and bean (Phaseolus vulgaris L. cv. Red Kidney) explants was 2-fold. It increased ethylene production from the explants, which was found to account for some of its ability to accelerate abscission. Absci is acid also increased the activity of cellulase. Increased synthesis of cellulase was not du to an increase in agin...

In this study, cellulase was modified by immobilization technique using MIL-88B(Fe) as the carrier, and temperature, time, concentration pH of 30°C, 6 h, 1.2 mg/mL 5.0, respectively, were investigated optimal preparation conditions. Characterization analysis FT-IR, XRD TGA revealed that successful on did not disrupt integrity carrier lattice structure. Compared with free enzyme, Cellulase@MIL-8...

denim is a casual garment normally used by young people and extremely influential in shaping the fashion industry. among various garments, these garments are subjected to innovations. this work is an attempt to compare the different methods of stone washing using pumice stones, acid cellulases and neutral cellulases or in combination of these methods. the effects of different processing conditi...

Cellulase hyperproducing mutants derived from the fungus Trichoderma reesei QM9414 were analyzed. They exhibited higher filter-paper degrading activity and a lower growth rate than the wild-type QM9414 strain. Transcription of the cellobiohydrolase I and endoglucanase I genes in the mutants was also greater than that of QM9414, suggesting that cellulase hyperproduction by these mutants was regu...

Gusakov critiques our methodology for comparing the cellulolytic activity of the bacterial cellulase CelA with the fungal cellulase Cel7A. We address his concerns by clarifying some misconceptions, carefully referencing the literature, and justifying our approach to point out that the results from our study still stand.

BACKGROUND The model cellulolytic fungus Trichoderma reesei (teleomorph Hypocrea jecorina) is capable of responding to environmental cues to compete for nutrients in its natural saprophytic habitat despite its genome encodes fewer degradative enzymes. Efficient signalling pathways in perception and interpretation of environmental signals are indispensable in this process. Ras GTPases represent ...

Pseudomonas putida KT2442 is a bacterium with potential for use in bioremediation of chlorinated hydrocarbons in soils, and its behavior in the subsurface is believed to be controlled by surface polymers. The role of surface macromolecules on the retention and adhesion behavior of this bacterium was examined by bacterial treatment with cellulase, an enzyme that breaks down the (1 4) linkages of...

BACKGROUND Over a 10 year period a decline in the rate of sensitizations to α-amylase (Aspergillus oryzae) was observed in bakers investigated for allergic obstructive airway disease. At the same time, glucoamylase (Aspergillus niger) was identified as the currently the most relevant allergen in sensitizations to enzymes in the baking industry. The aim of the present study was to investigate wh...

The prokaryotic residents of the Tis solar saltern in the southeast of Iran on the shore of Oman Sea were investigated by the culture-dependent methods. Sequencing of the PCR-amplified fragments of 16S rRNA genes revealed that bacterial populations were related to Actinobacteria, Bacteroidetes, Balneolaeota, Firmicutes, and Proteobacteria. T...
