Melt spinnabilities of thermoplastic paramylon mixed esters

open access: yesHeliyon, 2019
The low thermoplasticities of polysaccharide esters make them unsuitable for melt spinning. In this study, we aimed to overcome this problem by mixed esterification of paramylon, a euglenoid β-1,3-glucan with short- and medium-chain acyl groups, as melt ...

Diastereoselective Cyclization of a Glycyl-alanine Azomethine to an Imidazolidinone: Determination of the Product Configuration by X-Ray Analysis

open access: yesCHIMIA, 1989
Glycyl-(5')-alanine-esters 1 and 2 can be condensed to the corresponding 4-oxo-imidazolidin-3-yl-propionates 3 and 4, respectively. The diastereomers 3a and 4a are formed preferentially and the configuration was found to be u by single crystal X-ray ...

INFLEUNCE OF MICROBIAL INTERACTIONS ON IN VITRO CELLULOLYING ACTIVITY OF RUMEN FUNGI. [PDF]

open access: yesVeterinary Medical Journal - Giza, 2007
As ruminants in Egypt are mainly fed on lignocellulosic agricultural by-products, so the present study aimed to investigate the fungal cellulolytic activity in absence of cither rumen bacterial or protozoal populations after 12 and 24 hours of in vitro ...
