The best condition of extracting pectin from pomelo peel with the method of Al2(SO4)3 salting out was:filtrate∶Al2(SO4)3=1∶1,filtrate pH 5.5,temperature of salting out 45 ℃,time of salting out 1 h and pectin lead to 20.33%.
The optimal fermentation conditions were investigated: initial pH7.0, temperature 33℃, with 2% citrus peel powder and 1% lactose as carbon source, 1% (NH4)2SO4 and 0.3% yeast extract paste as nitrogen source, after fermenting for 32h on a rotary shaker.
Infection of treated Red Globle grape was decreased but not significantly in storage period, the content of resveratrol and piceid in grape peel was 100.28 μg/100 g·FW and 1 712.59 μg/100 g·FW respectly and was enhanced 3 and 7 fold compared with control at 8 days after 1.8 kj/m2UV-C treatment.
The existing accumulation of Mn,Zn,Pb,Cu,Cd,Ni elements in standing corps of the plantation were respectively 34. 047,3.351,1. 226,0. 874,0. 245,0. 084 kg ·hm-2 , the spatial distribution sequence of heavy metal elements pool amounts in different components ranked as trunk>bark>root>leaf>branch.
Published and original data on the organization and ultrastructure of the subsurface (cutaneous) musculature, basal plate, and intercellular matrix of acanthocephalans (spiny-headed worms) were analyzed and reviewed.
Similar to flatworms, the basal plate and the intercellular matrix of acanthocephalans proved to be derived from the cutaneous musculature.
Specific structure of acanthocephalan cutaneous muscles (the lacunar system, "nuclear secretion," specific block arrangement of myofilaments, etc.) allows us to consider it as a special kind of smooth muscle tissue.
The mussel proved to increase the resistance to epitheliomata and cutaneous mycoses.
Cutaneous Afferent Signal as a Modulator of the Heteronymous Influence of Primary Muscle Afferents
Treatment with the composite preparation was followed by an increase in ethylene release from both the whole apples and peel disks.
In model experiments, BHA decreased ethylene release from apple peel disks below control levels as early as on the first day after treatment.
The rheological properties of ethylene-vinyl acetate copolymers of various compositions in blends with pectins of various origins (pectins recovered from apple pulp, watermelon peel, and citrus fruits) were studied.
Bleaching of buckwheat straw and peel with potassium peroxoborate
We found that, for spectrophotometric pigment analysis in the apple peel, the cuticular lipids must be preliminarily extracted from the samples with chloroform and MgO must be added during homogenization to prevent pigment degradation.
Two new C19 quassinoids 1 and 2 were isolated from the stem bark of Ailanthus excelsa along with three known quassinoids excelsin, glaucarubin and polyandrol.
marcopoli Obenberger), is an important bark beetle attacking ash trees (Fraxinus spp.).
Oligosaccharide Specificity of the Fucolectin from the Bark of Laburnum (Laburnum anagyroides)
In the second case, the vigor was evaluated from the size of the necrotic spot on inner bark of the tree after inoculation of 22-25 randomly chosen pines with the extract of fungus Ceratocystis laricicola Redfern and Minter.
The optimal separation of phenolic components of the bark of basket willow Salix viminalis L.
