Taxis are an important transportation mode in many cities due to their convenience and accessibility. In the taxi-dispatching problem, sometimes it is more beneficial for the supplier if taxis cruise in the network after serving the first request to pick up the next passenger, while sometimes it is better that they wait in stations for new trip req...

Grain-batch variation in xylanase-inhibitor levels may account for variations in the efficacy of feed xylanase supplementation. This would make inhibition an important quality parameter in the routine analysis of feedstuffs. Two analytical procedures for testing feedstuffs against specific xylanases were researched: the high-throughput viscosity-pr...

At the end of 1990s two structurally different proteinaceous inhibitors of xylanases were discovered in the grain of wheat (Triticum aestivum). They were named TAXI (T. aestivum xylanase inhibitor) and XIP (xylanase-inhibiting protein). Later it was shown that TAXI and XIP in wheat are present in several isoforms encoded by different genes. TAXI- a...
The functionality of the proteinaceous wheat xylanase inhibitor XIP-I in Aspergillus niger endoxylanase-aided breadmaking was investigated using small-scale breadmaking and in vitro experiments. At an optimal dosage for an increase in bread volume, the endoxylanase provoked a ∼15% increase of loaf volume in standard flour experiments, but the dough...
A xylanase from Aspergillus aculeatus (glycoside hydrolase family 10), uninhibited by TAXI, and a xylanase from Bacillus subtilis (family 11), uninhibited by XIP-I, were selected to quantify the respective apparent levels of XIP-I and TAXI inhibitors, in flours and grains of 20 wheat varieties. The apparent TAXI amount ranged from 0.05 to 0.19 mg/g...

The phytopathogen fungus Botrytis cinerea produces various glycosidases which are secreted during plant infection. In this study, the XynBc1 cDNA that encodes a xylanase from family 11 glycoside hydrolase from B. cinerea was identified by homology-based analysis, cloned by reverse transcription RT-PCR, fully sequenced, and heterologously expressed ...
