Research ArticleOpen accessIn the abstractPalynological Studies of Sediments from North Chioma-3 Well, Niger Delta and its Palaeoenvironmental InterpretationsOlugbenga Ebenezer Ige, Kalyani Datta, Kanak Sahai, Krishna Kumar RawatProblem statement: The Niger Delta Nigeria stands among the world's best-studies delta complexes but its superficial deposits are among the poorest known publicity. In spite of continuous oil prospecting production in the area, there is still a paucity of published information and data on the palynology of the Niger Delta. This study aimed at reconstructing the palaeoenvironments of the Niger … …American Journal of Applied Sciences, Vol. 8, Issue 12 · 10 Oct 2011 · 7,884 accessesView PDF Cite

Research ArticleOpen accessIn the abstractIncorporation of Bentazone with Exserohilum rostratum for Controlling Cyperus iriaFranklin Ragai Kundat, Loo Hong Shen, Osumanu Haruna AhmedProblem statement: Various methods are used to counter the population of Cyperus iria in rice fields and among the most common method are chemical approaches. Chemical control methods are preferred by rice farmers due to their efficacy, speed, ease of storage and affordable cost. The concern of chemical herbicides is on its effects on the environment. Less attention had been … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 2 · 5 Sep 2011 · 9,525 accessesView PDF Cite

Research ArticleOpen accessIn the abstractUse of a Mixture of Thermophilic Enzymes Produced by the Fungus Thermoascus aurantiacus to Enhance the Enzymatic Hydrolysis of the Sugarcane Bagasse CelluloseJ. R. Monte, W. Carvalho, A. M. F. MilagresProblem statement: The production of hydrolytic enzymes by T. aurantiacus has been performed under solid-state fermentations using lignocellulosic materials. The influences of the inoculum size and of the fermentation medium on the production of hemicellulases and cellulases were studied. Filtrates from the cultures were used to hydrolyze a pulp of sugarcane bagasse and the produced enzymes were shown to be … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 4 · 13 Dec 2010 · 9,212 accessesView PDF Cite

Research ArticleOpen accessIn the abstractFungal Culture Systems for Production of Antioxidant Phenolics Using Pecan Nut Shells as Sole Carbon SourceMiguel A. Medina, Ruth E. Belmares, Antonio Aguilera-Carbo et al.Problem statement: Many agro-industrial wastes have little or none utilization, when these materials could be a very rich source of several value-added compounds, such as: the pecan nut shells, which contain Antioxidant Phenolic (AP) molecules like tannins. Approach: In this study, a bioprocess for the liberation of AP from Pecan Nut Shells (PNS) was described. A chemical characterization of raw … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 3 · 30 Sep 2010 · 8,042 accessesView PDF Cite

Research ArticleOpen accessIn the abstractTransgenic Indian Cotton (Gossypium hirsutum) Harboring Rice Chitinase Gene (Chi II) Confers Resistance to Two Fungal PathogensM. Ganesan, P. Bhanumathi, K. Ganesh Kumari et al.Problem statement: The present investigation described a simple and reproducible protocol for transgenic cotton regeneration and characterization of chitinase (Chi II) gene expression against two different fungal pathogens in cotton. Approach: Transgenic cotton (Gossypium hirsutum cv. SVPR2) plants were produced by pCambia-bar-Chi II (13.8 kb) under the control of the CaMV 35S promoter, harbored in the strain LBA 4404 Agrobacterium … …American Journal of Biochemistry and Biotechnology, Vol. 5, Issue 2 · 30 Jun 2009 · 8,531 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPotential Strain to Produce Bioprotein from Cheaper Carbon Source: Hope for MillionsParveen Jamal, Md. Zahangir Alam, Nurul UmiBioprotein production is one of the most promising breakthroughs of biotechnological innovations. Due to its increasing demand, the efficient strains, substrate and method must be used for high yield product. In this study, screening of five different cerivisiea, Mucor hiemalis and Thricoderma harzianum, was done for bioprotein production by liquid state bioconversion of wheat flour as a cheaper carbon source. … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 2 · 30 Jun 2007 · 7,807 accessesView PDF Cite
