a study was carried out on totally chlorine-free (tcf) bleachability of dimethyl formamide (dmf) treated bagasse pulps exposed to cz-3 and fp 90031-sp strains of white-rot fungus ceriporiopsis subvermispora. this process involved an oxygen and peroxide stage bleaching sequence. the effect of enzymatic stage on bleachability properties was studied and compared with control pulps, processed witho...
Nocardia cultures, isolated from soil by use of n-paraffins as the sole carbon source, have been shown to bring about significant oxidation of several methyl-substituted mono- and dicyclic aromatic hydrocarbons. Oxygen uptake by washed cell suspensions was not a reliable indicator of oxidation. Under co-oxidation conditions in shaken flasks, o- and p-xylenes were oxidized to their respective mo...
Comparative in vitro study of the inhibition of human and hen esterases by methamidophos enantiomers
The essential oils from two Chinese endemic Meconopsis species, i. e., M. punicea and M. delavayi, were analyzed by using GC-MS for the first time. The major constituents were hexadecanoic acid (16.8%), 1,2-dimethyl naphthalene (11.4%), 1,4-dimethyl naphthalene (6.6%), 1,3-dimethyl-5-ethyl naphthalene (5.9%), and 3-methyl biphenyl (5.6%) for M. punicea, and hexadecanoic acid (9.9%), 1,2-dimethy...
This paper presents the results of studies anti-seize properties (2,2-dimethyl-4-methylene1,3-dioxolane-allyl and benzyl)disulfides synthesized on basis 2,2-dimethyl-4-chloromethyl-1,3- dioxolane, sodium disulfide allyl benzyl chlorides, respectively, in composition transmission oils. The compounds are new not previously described literature, structure which has been proven by studying their ph...
