Research ArticleOpen accessIn the abstractIsolation and Physical Characterization of Hydrophobin-Like Proteins (HLP) from Aerial Conidia of Metarhizium Anisopliae Var. AnisopliaeD. S.B. Kiong, Choon Fah J. Bong, P. J.H. KingThe aim of this study was to isolate and physically characterized Hyrophobin-Like Proteins (HLP) from the aerial conidia of two local isolates of Metarhizium anisopliae var. anisopliae, namely, TA and LR2. The protein samples were isolated based on their insolubility in hot Sodium Dodecyl Sulfate (SDS). The SDS-insoluble proteins were then purified in cold 98% formic acid and performic acid. … …American Journal of Biochemistry and Biotechnology, Vol. 11, Issue 2 · 29 Jan 2015 · 7,776 accessesView PDFCite
Research ArticleOpen accessIn the abstractMOLECULAR CHARACTERIZATION AND IMMUNOPROTECTIVE ACTIVITY OF CAPSULAR POLYSACCHARIDE OF KLEBSIELLA PNEUMONIAE ISOLATED FROM FARM ANIMALS AT TAIF GOVERNORATEAhmed M.A. Mansour, Hoda M. Zaki, Nibal A. Hassan, Abdulrahman A. Al-HumianyKlebsiella pneumoniae is a Gram-negative enterobacterium that has historically been and currently remains, a significant cause of human disease and several kinds of infections in animals. In the present work, trials for the isolation of Klebsiella pneumoniae from diseased and apparently healthy farm animals (cows, sheep, goats and camels) were done for recognition of Klebsiella pneumoniae subspecies. It was noticed … …American Journal of Infectious Diseases, Vol. 10, Issue 1 · 6 Jan 2014 · 7,937 accessesView PDFCite
Research ArticleOpen accessIn the abstractElectrophoretic Analysis of Protein Patterns in Date Palm &#34Khalas&#34 Cultivar Leaflets Among Different Locations of Al-AhsaAl-Issa Adil MohammadProteins extracted from different date palm (Phoenix dactylifera L.) trees &#34Khalas&#34 Cultivar leaflets, which were collected from 10 different locations of Al-Ahsa oasis in the eastern province of Saudi Arabia, have been analyzed by SDS-PAGE electrophoresis. The present study showed different protein patterns, which revealed by NJ and UPGMA clustering methods into three major clusters 1, 2 and 3. Cluster … …American Journal of Agricultural and Biological Sciences, Vol. 8, Issue 4 · 7 Nov 2013 · 7,280 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdsorption Study of Rhodamin B Dye on Iraqi Bentonite and Modified Bentonite by Nanocompounds TIO2, ZNO, AL2O3 and Sodium Dodecyl SulfateIqbal Salman AL-Jobouri, Saadiyah Ahmed Dhahir, Khulood Abed AL-SaadeThe adsorption of Rhodamin B on Iraqi bentonite at the concentration range from 50 to 250 µg mL-1 was studied, Nano compounds; ZnO, TiO2, Al2O3 m and SDS in different amounts 0.01-0.1 g 10-1 g of Bentonite were used to modified the adsorption capacity of bentonite to remove the Rhodamin B from aqueous solutions. The study indicated that using 0.05 … …American Journal of Environmental Sciences, Vol. 9, Issue 3 · 19 Jul 2013 · 7,966 accessesView PDFCite
Research ArticleOpen accessIn the abstractAntigenic and Immunogenic Components of Haemonchus longistipes Identified by Western ImmunoblotingE. M. El Hassan, Sabry M. El-BahrThe present study aimed to examine the ways that the Haemonchus longistipes components interact with the host by investigating the components of the parasite which acted as antigens during infection and those who are capable of inducing immune response when administered as immunogens. Adult H. longistipes worms (300 females and 200 males) were obtained from the abomasums of naturally infected … …American Journal of Biochemistry and Biotechnology, Vol. 8, Issue 3 · 20 Sep 2012 · 7,498 accessesView PDFCite
Research ArticleOpen accessIn the abstractBioautography Guided Identification of Anticandidal Compounds from A. terreus st. 1B. K. Nagaraja, R. Sripathy, C. N. Ramchand, M. SundararamanProblem statement: Saprophytic and soil inhabiting microorganisms are prolific producers of secondary metabolites with wide range of structural and functional diversity. The objective of the current study was to screen and evaluate the anti-candidal properties of soil inhabiting fungi. Approach: Preliminary dual culture assay and bioautography was used to screen the fungi with potential anti-fungal activity and direct detection of … …American Journal of Infectious Diseases, Vol. 7, Issue 4 · 1 Dec 2011 · 7,629 accessesView PDFCite
Research ArticleOpen accessIn the abstractIdentification a Novel Raw-Starch-Degrading-α-Amylase from a Tropical Marine BacteriumZeily Nurachman, Alfredo Kono, Ocky Karna Radjasa, Dessy NataliaProblem statement: Bacteria from the surface of the tropical marine hard coral Acropora sp. were screened for producing raw-starch-degrading-α-amylase. Approach: Based on its 16s rDNA sequence, a bacterium that produced the highest amylolitic activity was identified as Bacillus amyloliquifaciens ABBD. The bacterial isolate secreted a α-amylase extracellularly and then the enzyme was partially purified by ammonium sulfate precipitation followed by … …American Journal of Biochemistry and Biotechnology, Vol. 6, Issue 4 · 31 Dec 2010 · 9,329 accessesView PDFCite
