Research ArticleOpen accessIn the abstractIDENTIFICATION, MOLECULAR CHARACTERIZATION AND EVALUATION OF SOME RUMINAL BACTERIA THAT CATALYZE AND DEGRADE PLANT CELLULOSIC MATERIALSAhmed A. Mansour, T. S. El-Tayeb, N. E. El-BordenyIn the last few years there was a growing economic awareness about plant wastes and use it in compost production or in feeding of farm animals, some of these wastes are useless and cause a lot of problems in Egyptian environment. This study was designed to isolate, identify and evaluate some ruminal bacterial isolates to facilitate the in vitro degradation … …American Journal of Applied Sciences, Vol. 11, Issue 1 · 10 Dec 2013 · 7,137 accessesView PDFCite
Research ArticleOpen accessIn the abstractStrains of Klebsiella Pneumoniae from Intensive Care Unit Producing CTX-M-15 Extended Spectrum Beta LactamasesI.R. Iroha, A.E. Oji, A.E. Nwakaeze et al.Problem statement: Resistance to third generation cephalosporins due to acquisition and expression of Extended Spectrum β-Lactamase (ESBL) among Gram-negative bacteria is on the increase. Infections involving extended spectrum beta lactamase bacteria are associated with significant morbidity and mortality. Therefore, infections due to ESBL isolates continue to pose a serious challenge to infection management worldwide. Since screening for ESBL is not … …Current Research in Microbiology, Vol. 2, Issue 2 · 6 Mar 2012 · 7,828 accessesView PDFCite
Research ArticleOpen accessIn the abstractSynthesis and Characterization of Organotin(IV) Complexes Derived of 2-amino-5-nitrobenzoic Acid: In vitro Antibacterial Screening ActivityYip-Foo Win, Siang-Guan Teoh, M. R. Vikneswaran et al.Problem statement: Tremendous studies have been carried out on organotin(IV) complexes derivatives of carboxylate anions. However, the synthesis and characterization as well as the in vitro antibacterial screening activity of organotin(IV) carboxylate derived of 2-amino-5-nitrobenzoic acid have not been carried out. Approach: Organotin(IV) carboxylate complexes derivative of 2-amino-5-nitrobenzoic acid, 2-NH2-5-NO2-C6H3COOH have been successfully synthesized. The acid and complexes obtained were … …American Journal of Applied Sciences, Vol. 7, Issue 7 · 31 Jul 2010 · 8,801 accessesView PDFCite
Research ArticleOpen accessIn the abstractBheri-A Unique Example of Biological Complex SystemIndranil Mukherjee, Pranami Bhaumik, Madhusmita Mishra et al.Problem statement: This study is a unique attempt to characterize Bheri (shallow flat bottom waste water fed fishery) as a complex biological system. Approach: The characterization was done both at the qualitative and the quantitative levels. The diverse microbial community and the associated emergent behaviors resulting in integrated resource recovery by the Bheris were analyzed under the lens of complexity … …OnLine Journal of Biological Sciences, Vol. 10, Issue 1 · 30 Jun 2010 · 7,775 accessesView PDFCite
Research ArticleOpen accessIn the abstractSynthesis and Characterization of Organotin(IV) Complexes Derived of 3-(Dimethylamino)benzoic Acid: Cytotoxic Assay on Human Liver Carcinoma Cells (HepG2)Yip-Foo Win, Siang-Guan Teoh, Tengku-Sifzizul Tengku-Muhammad et al.Problem statement: Many studies have been carried out on organotin(IV) complexes derivative of carboxylate anions. However, the synthesis and characterization as well as the cytotoxic assay of organotin(IV) carboxylate derived of 3-(dimethylamino)benzoic acid have not been studied. Approach: Organotin(IV) carboxylate complexes derivative of 3-(dimethylamino)benzoic acid, 3-[N(CH3)2]C6H4COOH have been successfully synthesized. Two types of diorganotin(IV) complexes, [{3-[N(CH3)2]C6H4COO(R)2Sn}2O]2 dimer (R = methyl … …American Journal of Applied Sciences, Vol. 7, Issue 3 · 31 Mar 2010 · 8,315 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Morphological, Biochemical and Biological Studies of Halophilic Streptomyces sp. Isolated from Saltpan EnvironmentDeepika T. Lakshmipathy, Krishnan KannabiranProblem statement: Dermatophytes have developed resistance to the existing antifungal antibiotics. As a part of our continuous search we had isolated, identified and characterized actinomycetes from the halophilic environment having antagonistic activity against the dermatophytes namely Trichophyton, Microsporum and Epidermophyton. Approach: Actinomycetes were isolated from the soil sample collected from the Ennore saltpan region, Chennai, India and screened for antidermatophytic … …American Journal of Infectious Diseases, Vol. 5, Issue 3 · 30 Sep 2009 · 7,743 accessesView PDFCite
Research ArticleOpen accessIn the abstractGenetic Diversity of the Beet Distributed in Armenia Using Protein MarkersTatevik Aloyan, Manvel Badalyan, Andreas MelikyanThe genetic resources of plants and animals are the wealth of every country. They are a valuable starting material in the breeding processes of cultivated plants and farm animals. In order to improve the existing varieties of crops and obtain new, valuable varieties, it is very important to document, preserve and enrich their gene pool, while preserving local varieties and … …OnLine Journal of Biological Sciences, Vol. 23, Issue 4 · 11 Sep 2023 · 4,634 accessesView PDFCite
