The results indicate that ultrasound alone could initiate lipid peroxidation and lecithoid configuration degradation resulting in membrane fluidity decline.
Both enzymatic pathway (degradation by keratinase) and non-enzymatic pathway that is sulfitolysis occurred in the degradation process by streptomycete sp.B221.
As a new technology of organic pollutant degradation, the photocalalytic method, which effectively decomposes nondegradable pollutants, is becoming increasingly important in wastewater treatment.
On the basis of mechanism analysis and compare of CODCr degradation rate, parachlorophenol and aniline were found to be easier degraded by ferrate than nitrobenzene.
This paper briefs the industrial usages i and harmfulness of cyclopentanone and cyclohexanone, and reviews the research progresses in microbial degradation of cyclopentanone and cyclohexanone.
Bio - degradation role of aerobiotic organic substance and relationships between biological degradation and dissolved oxygen were stated, which provided theoretical basis for waste water reatment.
In the present study, observations were made to determine if the yolk protein, vitellin, was released from the ovaries into the hemolymph without degradation during oosorption.
Moreover, it was shown that degradation of lignin was promoted by veratryl alcohol added, no effect of veratryl alco-hol on degradation of cellulose and hemicellulose was detected.
The result indicates that the main metabolic product of petroleum hydrocarbon degradation is acetic acid and surface active agent of glycolipid composed of fatty acid and rhamnose.
The application of surfactant in microbial degradation of petroleum pollution in recent years is introduced in this paper and the factors of choosing the eptitude surfactant are also disc.
The process of change for thermo-oxidative degradation of latex film at different vulcanization time during the prevulcanization of latex by peroxide was studied by using of TG-DTG and DTA.
