Research ArticleOpen accessIn the keywordsProduction of (E) 10-Hydroxy-8-octadecenoic Acid with Lyophilized Microbial CellsA. Bódalo, J. Bastida, M.F. Máximo et al.Lyophilized non-proliferating microbial cells of Pseudomonas sp. 42A2 showed their ability to catalyze the bioconversion of oleic acid into (E)-10-hydroxy-8-octadecenoic acid (MHOD) and (E)- 7,10-dihydroxy-8-octadecenoic acid (DHOD). The reaction conditions were optimized in order to produce the maximum amount of MHOD. At 30°C and using phosphate buffer (0.1 M and pH=8), an initial substrate concentration of 10 mg mL-1 and … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 1 · 31 Mar 2005 · 7,162 accessesView PDFCite
Research ArticleOpen accessIn the abstractA NAPIN PROMOTER ACTIVATES GENE EXPRESSION IN DEVELOPING SEEDS OF LESQUERELLA FENDLERIGrace Q. Chen, Jiann-Tsyh LinLesquerella fendleri produces industrial useful Hydroxy Fatty Acids (HFA) in seed oil. To improve oil and HFA of L. fendleri, it is desirable to use of seed-specific promoters to control the expression of target genes by genetic engineering. A seed-specific promoter fragment, -397 to -1 of a napin gene (PnapA) from Brassic napus was isolated by PCR and constructed to … …OnLine Journal of Biological Sciences, Vol. 12, Issue 3 · 18 Sep 2012 · 7,890 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Crude Aqueous Extract of Piper betle L. and its Antibacterial Effect Towards Streptococcus mutansT. Nalina, Z.H.A. RahimIn this study, the antimicrobial influence of crude aqueous extract of Piper betle L. on Streptococcus mutans (S. mutans) was investigated. The focus of the antimicrobial effects includes the ultrastructure and acid producing properties of S. mutans. Transmission electron microscopy (TEM) was used to determine the effect of the extract on the ultrastructure of S. mutans. Analysis of the effect … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 1 · 31 Mar 2007 · 13,459 accessesView PDFCite
