The results indicate that polyborazine precursor prepared at 150℃ for 10 h and propylamine/isopropylamine molar ratio 2:1, could possess nearly linear molecule skeleton and he prone to melt spinnability. When melt at 90℃, the precursor fibers are prepared with average diameter 10-20μm and BC1.27 N1.52 H structure. After curing process and sintered in NH3 at 1200℃, the near-stoichiometric BN fibers was obtained, which proved this precursor is apt for preparation of BN fibers.

D limonene was distributed among the culture flasks (200 mg/L). The flasks were incubated at 28oC on a rotary shaker (r/min=120) for 5 days. On completion, the culture broth were successively extracted with EtOAc. The extract was quantitatively measured by gas chromatography mass spectrometry analysis, The results showed that biocatalytic reactions were comprised of oxidation, including hydroxylation and ketonization which occurred at different positions of the D limonene, as well as hydrogenation, hydrolyzation, esterification and cyclic cleavage. These bacteria strains possess the distinctive biocatalytic capacities towards the D limonene. A series of terpenoids, including sesqui , di and tri terpernoids were also observed,which was accounted for D limonene had influence on the metabolites of marine bacteria.
