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 ... -
Conservation And Cultural Aspect Of Mkilua Fragrans Verdc. At The Kenyan Coastal Lowlands
(INTERNATIONAL JOURNAL OF SCIENTIFIC & TECHNOLOGY RESEARCH, 2014-05)Mkilua fragrans Verdc belongs to the Annonaceae family and is part of the biological diversity of the coastal forests of east African coast region. The Swahili and Digo communities of the kenyan coastal lowlands have engaged ... -
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. ... -
Utility of the Ammonia-Free Birch Reduction of Electron-Deficient Pyrroles: Total Synthesis of the 20S Proteasome Inhibitor, clasto-Lactacystin b-Lactone
(Chem. Eur. J., 2005)A new synthesis of the 20S proteasome inhibitor clasto-lactacystin b-lactone is described. Our route to this important natural product involves the partial reduction of an electron deficient pyrrole as a key step. By ... -
11α-Hydroxy muzigadiolide, a novel drimane sesquiterpene from the stem bark of warburgia ugandensis
(Bulletin of the Chemical Society of Ethiopia, 1999-12-03)The plant was identified by Prof. MS Rajab by comparison with a preserved standard specimen at the National Museum I-lerbarium in Nairobi, Kenya. . -
Degradation of dichlorodiphenyltrichloroethane (DDT) by bacterial isolates from cultivated and uncultivated soil
(Academic Journals, 2010-02-04)The re-introduction of dichlorodiphenyltrichloroethane (DDT) to control mosquitos was recommended by the World Health Organization in 2007. In this study, the potential for biodegradation of DDT by soil microorganisms ... -
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 ... -
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 ... -
Chemiluminescencedetection of aminoacids using an Edman-typereagent, 4-(1′-cyanoisoindolyl)phenylisothiocyanate
(ELSELVIER, 2005-04-11)The 4-(1′-cyanoisoindolyl)phenylisothiocyanate (CIPIC) could be used as a chemiluminescence (CL) Edman-typereagent. Firstly, CL reaction conditions such as pH, buffer types, H2O2 concentration and organic solvents were ... -
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 ... -
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 ... -
