bacillus sp. sbs25, a gram positive bacteria isolated from soil was found to be effectivein the biodegradation of natural rubber latex. the products of latex biodegradation were separated from the ether extract by thin layer chromatography. gas chromatography and mass spectrometry showed the biodegradation of the major compound into three simpler fractions with low molecular weights. this was f...

BACKGROUND Natural rubber produced by plants, known as polyisoprene, is the most widely used isoprenoid polymer. Plant polyisoprenes can be classified into two types; cis-polyisoprene and trans-polyisoprene, depending on the type of polymerization of the isoprene unit. More than 2000 species of higher plants produce latex consisting of cis-polyisoprene. Hevea brasiliensis (rubber tree) produces...

Natural polyisoprene is a biopolymer consisting of isoprene units (C(5)H(8)) that is used commercially in household, medical, and industrial materials. For the management of natural polyisoprene production, the selection of high-yield polyisoprene-producing trees, and an understanding of polyisoprene biosynthesis, a high-throughput and highly sensitive screening method for the quantification of...

The cytosolic mevalonate (MVA) pathway in Hevea brasiliensis latex is the conventionally accepted pathway which provides isopentenyl diphosphate (IPP) for cis-polyisoprene (rubber) biosynthesis. However, the plastidic 2-C-methyl-D-erythritol 4-phosphate (MEP) pathway may be an alternative source of IPP since its more recent discovery in plants. Quantitative RT-PCR (qRT-PCR) expression profiles ...
