A new compound, 4-acetyl-5-hydroxy-3, 6, 7-trimethylbenzofuran-2(3H)-one (1), together with two known compounds, 2-carboxy-3-(2-hydroxypropanyl) phenol (2) and 5-methyl- 6-hydroxy-8-methyoxy-3-methylisochroman (3) were isolated from the fungus Alternaria sp. (HS-3) associated with a sea cucumber from the Yellow Sea in China. Their structures were elucidated by spectral methods.

Isolation And Characterization

Three compouds, (+)-butyrolactone IV (1), butyrolactone I (2) and terrelactone A (3) were isolated from the fungus Aspergillus terreus associated with Apostichopus japonicus from the Yellow Sea in China; their structures were elucidated by spectral methods. Compounds 1 and 2 were shown to have moderate antiangiogenesis activity when tested using the zebrafish assay. This is the first report of butyrolactones with antiangiogenesis activity.

First Time

One cold-adapted strain, named Planococcus sp. XW-1, was isolated from the Yellow Sea. The strain can produce biosurfactant with petroleum as sole source of carbon at low temperature (4 °C). The biosurfactant was identified as glycolipid-type biosurfactant species by thin-layer chromatography (TLC) and Fourier transform infrared spectroscopy (FTIR). It reduced the surface tension of water to 26.8 mN/m with a critical micelle concentration measurement of 60 mg/L. The produced biosurfactant possesses high surface activity at wide ranges of temperature (−18–105 °C), pH values (2–12), and salt concentrations (1–18%). The biosurfactant exhibited higher surface activity and higher growth rate of cells with hexadecane and diesel as carbon source. The strain Planococcus sp. XW-1 was also effective in degrading crude oil, after 21 days of growth at 4 °C in medium with 1% crude oil and 1% (v/v) bacteria broth, 54% of crude oil was degraded. The results suggest that Planococcus sp. XW-1 is a promising candidate for use in the bioremediation of petroleum-contaminated seawater in the Yellow Sea during winter. This study reported for the first time that Planococcus isolated from the Yellow Sea can produce biosurfactant using petroleum as the sole carbon source at low temperature (4 °C), showing its ecological role in the remediation of marine petroleum pollution.

The isolation and characterization of a novel triterpene glycoside from the sea cucumber Cucumariafrondosa, collected from the Gulf of St. Lawrence, are described. Physico-chemical data obtained on the underivatized saponin are presented in support of structure 1 for frondoside A. The structure is characterized by the presence of a branched oligosaccharidic chain composed of five units. The holostane-type aglycone features an endocyclic double bond at position C-7,8 and a β-acetoxy group at C-16. Keywords: triterpene glycoside; Cucumariafrondosa saponins; saponins, triterpene from holothurians; holothurian saponins; echinoderm triterpene saponins.
