Abstract
Reaction of alkenes [cyclohexene (1), cycloheptene (2), cyclooctene (3), 1-heptene (4), 1-octene (5), styrene (6), 1,7-octadiene (7), indene (8), and 1,2-dihydronaphthalene (9)] with cerium(IV) sulfate (CS) in carboxylic acids [formic acid, acetic acid, and propionic acid] readily yielded the corresponding carboxylic esters. This addition reaction follows the Markovnikov rule. This reaction provides a new simple method for preparing carboxylic esters from alkenes. It was also found that this method is useful for formylation.

Abstract
Biotransformation of bromosesquiterpenes was investigated with two types of fungi, Rhinocladiella atrovirens NRBC 32362 and also Rhinocladiella sp. K-001, isolated from the Okinawan brown alga Stypopodium zonale. R. atrovirens NRBC 32362 converted aplysistatin 1 into three compounds 5alpha-hydroxyaplysistatin 4, 5alpha-hydroxyisoaplysistatin 5 and 9beta-hydroxyaplysistatin 6. Transformation of 1, palisadin A 2 and 12-hydroxypalisadin B 3 by Rhinocladiella sp. K-001 gave two compounds, 3,4-dihydroaplysistatin 7 and 9,10-dehydrobromopalisadin A 8.

Abstract
Some difficulties on a sampling of gaseous glyoxal using DNPH-silica cartridge were discussed, and an alternative sampling procedure was proposed. When glyoxal was sampled using the cartridge, it partially formed mono-hydrazone with various degrees, whereas it was quantitatively converted into its bis-hydrazone when sample gas was directly bubbled into a DNPH acidic solution. Additionally, glyoxal polymerized on the inner wall of the system during trapping to the silica cartridge. We found that the polymerization of glyoxal was effectively suppressed by dissolving glyoxal into methanol under reduced pressure; glyoxal in methanol readily reacted with DNPH in a hydrochloric acid solution and gave bis-hydrazone derivative, without any interference of methanol and any formation of mono-hydrazone derivative. When glyoxal was sampled by the proposed method, 102% of recovery was obtained, whereas it was reduced to 92.7% when the trapped glyoxal was dissolved into methanol under atmosphere.

Abstract
The biologic degradation of 2,2-bis(4-hydroxyphenyl)propane (bisphenol A [BPA]; 1) was studied with 26 fungi. An initial BPA concentration of 40 ppm in an aqueous solution was degraded in the dark for 14 d. Among the 26 strains tested, 11 degraded BPA at 50% or more. Furthermore, four strains (F. sporotrichioides NFRI-1012, F. moniliforme 2-2, A. terreus MT-13, and E. nidulans MT-98) were more effective for degradation of BPA.
