526 IU/g), FPase (3.268 IU/g), and B-glucosidase (50.696 IU/g). Among the nitrogen sources, urea caused maximum production of CMCase (81.832 IU/g), where as casein and soyabean meal gave the highest FPase (4.682 IU/g) and beta-glucosidase (69.083 IU/g) production, respectively. LY3039478 Among amino acids tested glutamic acid gave the highest production for CMCase (84.127 IU/g); however 4-hydroxy-L-proline stimulated maximum FPase production (6.762 IU/g). Saccharification of pretreated rice straw and wheat straw by crude enzyme extract from Fomitopsis sp. RCK2010 resulted in release of 157.160
and 214.044 mg/g of reducing sugar, respectively. (C) 2011 Elsevier Ltd. All rights reserved.”
“Microencapsulation with beta-cyclodextrin (beta-CD) as a delivery platform offers a promising application for natural antimicrobial delivery for food safety. Hence, this study aimed to characterize inclusion complexes of thymol and thyme essential oil with beta-CD and their resulting antimicrobial activities. Inclusion complexes were prepared by kneading (KN) and freeze-drying (FD) methods. The entrapment efficiencies ranged from 71 to 83 g/100 g with higher (P smaller than 0.05) values for thymol and FD particles. All particles showed irregular shapes and sharp edges with significant differences in size distribution
and strong tendency to agglomerate. FD produced higher (P smaller than 0.05) particle sizes than KN method. Differential Scanning Calorimetry (DSC) analysis confirmed inclusion complexes formation between beta-CD and both compounds. Phase solubility tests indicated B-s-type complexes formation between thymol QNZ and beta-CD. All compounds effectively inhibited bacterial growth within the concentration range tested. Free thyme oil showed higher (P smaller than
Selleckchem ABT-263 0.05) antimicrobial activity than thymol, and FD beta-CD inclusion complexes were able to inhibit Escherichia coli K12 at lower (P smaller than 0.05) active compound concentrations than corresponding free oils. Antimicrobial activities of beta-CD inclusion complexes against total viable counts in pork meat system throughout storage were observed. The FD method showed to be the best encapsulation method with enhanced antimicrobial activity for both compounds. Published by Elsevier Ltd.”
“This study investigates whether the diagnosis-related group (DRG)-based payment method motivates hospitals to adjust output mix in order to maximise profits. The hypothesis is that when there is an increase in profitability of a DRG, hospitals will increase the proportion of that DRG (own-price effects) and decrease those of other DRGs (cross-price effects), except in cases where there are scope economies in producing two different DRGs. This conjecture is tested in the context of the case payment scheme (CPS) under Taiwan’s National Health Insurance programme over the period of July 1999 to December 2004.
