Fluorescencedetection of aminoacids in the postcleavageconversions for manualsequencing of apeptide
(ELSELVIER, 2008-03-15)A modified Edman degradation method where fluorescent derivatives of aminoacids were generated from the postcleavage products of apeptide is described. In the method, the target peptide was applied onto double glass fiber ... -
Heavy metal tolerance and antibiotic resistance profiles of gram negative bacteria isolated from Lake Victoria, Kenya
(African Journals Online, 2007)Pollution and increased levels of heavy metals in the Lake Victoria Wetlands are suspected to be negatively influencing the biota in one of the world most important freshwater resources. In this study, fecal contamination ... -
Highregioselectivity in electrochemical α-methoxylation of N-protectedcyclicamines
(ELSELVIER, 2008-04)N-Protecting groups of α-substituted cyclicamines strongly affected the regioselectivity in electrochemicalmethoxylation of these compounds. Namely, N-acyl derivatives were transformed into α′-methoxylated compounds, while ... -

NUTRITIONAL AND ANTIOXIDANT ANALYSIS OF PLEUROTUS HK 37 GROWN ON AGAVE SISALANA SALINE SOLID WASTE
(http://www.urpjournals.com, 2014)Mushrooms consumed in recent times have increased both in the amounts as well as the number of species consumed. The main bioactive components in mushroom are phenolic compounds, ascorbic acid, β-carotene and lycopene. ... -
Optimization of Pleurotus Mushroom Cultivation on Saline Sisal Solid Waste
(IDOSI Publications,, 2013)Mushrooms are a primary part of managing solid waste, building organic soil and returning minerals to the soil. Sisal processing in Kenya generates an estimated 611,875 tonnes of solid waste annually, which is discarded ... -
Poly(beta-hydroxybutyrate) production by a moderate halophile, Halomonas boliviensis LC1 using starch hydrolysate as substrate
(Blackwell, 2005)The objective of the present work was to enable the use of starch hydrolysate, generated by the action of a recombinant maltooligosaccharide forming amylase from Bacillus halodurans LBK 34, as the carbon source for the ... -

Reduction of electron-deficient pyrroles using group I and II metals in ammonia
(RSC Publishing, 1998)The preparation and Birch reduction of a series of electron-deficient pyrroles is described. This methodology allows the synthesis of a variety of C-2 substituted 3-pyrrolines ‡ in good to excellent yields. The role of ... -
Reductivealdolreactions on aromatic heterocycles
(Elsevier, 2000-02-12)The Birch reduction of both pyrroles and furans can be quenched with an aldehyde electrophile, thus constituting a reductivealdolreaction. Although the reaction was not stereoselective, the pyrrolines derived from reduction ... -
Ring Contraction of α,β-Unsaturated Cyclic Amines with cis-Dihydroxylation at the α,β-Position
(The Japan Institute of Heterocyclic Chemistry, 2009-01)α,β-Unsaturated cyclic amines are oxidized by OsO4 to afford α,β-cis-dihydroxylated compounds which are thermodynamically transformed into ring-opened keto-alcohols. The keto-alcohols are then cyclized to form synthetically ... -
Starch hydrolysing Bacillus halodurans isolates from a Kenyan soda lake
(2004)Fourteen obligate alkaliphilic and halotolerant bacterial isolates, exhibiting extracellular amylase activity at 55degreesC and pH 10, were isolated from hot springs around Lake Bogoria, Kenya. From 16S rDNA sequence ... -
The stereoselectiveBirchreduction of pyrroles
(ELSELVIER, 1999-01-15)The Birchreduction has been applied to electron-deficient pyrroles substituted with a chiral auxiliary at the C-2 position. Using either 8-phenylmenthol ortrans-2-(α-cumyl)cyclohexanol (TCC) as auxiliaries, high levels of ... -
Surfactants from xylan: Production of n-octyl xylosides using a highly thermostable xylanase from Thermotoga neapolitana
(Elsevier, 2010)A highly thermostable recombinant xylanase from Thermotoga neapolitana was used as a catalyst for single-step synthesis of n-octyl xylobioside and n-octyl xylotrioside from xylan and n-octanol. Effect of xylan concentration, ... -
