System temperature is 60℃, soya salad oil 28ml, Span80 1.6ml, chitosan hydrolyze time: 3 hour ,chitosan: Levofloxacin=l:1.7, time of polycondensationt is 0.5 hour , oikwater is 3.5:1 .drug-loading rate of chitosan-levofloxacin sustained-release microsphere is 43.88%.
It needs 30ml 2mol / L NaOH solution to hydrolyze 5g polysuccinimide. The temperature of hydrolyzable reaction ranges from 50-60℃ and the reaction time is 1.0 h.
On the basis of total acid hydrolysis, methylation analysis, periodate oxidation and NMR studies (1H and 13C) the structure of the repeating unit of the polysaccharide was assigned and indicated only α-(1→4) linked Glucan.
The structural information of the glucan was achieved by chemical (hydrolysis, methylation, periodate oxidation) and spectroscopic (1H and 13C) analyses, indicated a repeating unit built up of (1→6)-linked D-glucose.
Composting of hydrolytic lignin by a microbial association changed its molecular-weight composition, acid-base properties, and supramolecular structure.
Acid proteinases generated a large amount of low-molecular-weight products, confirming a wide specificity of their action and their ability to hydrolyze the peptide bonds formed by various amino acid residues.
The plants accumulating considerable amounts of pelargonidin in their petals have accordingly higher flavonol-degrading activity and predominantly hydrolyze kaempferol.
These antibodies (Abs), their Fab-fragments, and isolated light chains were shown to possess catalytic activity in DNA hydrolysis, whereas Abs from the sera of control healthy mice did not hydrolyze DNA.
The possibility of using xylanase preparations for hydrolyzing hemicelluloses in a non-bleached kraft pulp in order to facilitate its bleaching was studied.
Enzymes hydrolyzing 4-O-methyl-α-D-glucurono-β-D-xylan and sodium carboxymethyl xylan were also found in the culture liquid after 4 h of fungal growth.
