Falade, Goodness I. Omolaiye, Kayode E. Adewole et al.Neurological disorders remain a global health challenge, with Alzheimer’s Disease (AD) as the most famous cause of dementia in old people. Nevertheless, culinary spices and herbs have shown promising potentials in the management of neurological diseases. This study aimed at investigating the neuroprotective property of aqueous extracts of bay leaf (Laurus nobilis) and rosemary (Rosmarinus officinalis) by assessing the antioxidant … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 1 · 25 Jan 2022 · 7,955 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleEnhanced Fatty Acid Production in Escherichia coli by Over-Expression of NADPH Generating EnzymesYuanda Song, Yong Q. Chen, Haiqin Chen et al.NADPH is an essential factor for Fatty Acid (FA) biosynthesis. The effect of NADPH generating enzymes [NADP+-dependent malic enzyme (NADP-ME), NADP+-dependent isocitrate dehydrogenase (NADP-IDH), Glucose 6-Phosphate Dehydrogenase (GPD) and 6-Phosphogluconate Dehydrogenase (PGD)] on FA biosynthesis was investigated in an engineered Escherichia coli BL21 △fadE/pTE. Among NADPH-generating enzymes, GPD and ICD increased total FA production by 60 and 16% respectively. Especially … …American Journal of Biochemistry and Biotechnology, Vol. 13, Issue 4 · 23 Oct 2017 · 8,578 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleVARIABILITY IN THE LIGNINOLYTIC ENZYMES ACTIVITY BY LENTINULA EDODES IN SUBMERGED CULTURE WITH LIGNIN AND GLUCOSECitlalli Harris-Valle, Elisa Valenzuela-Soto, Alfonso Sánchez et al.The white-rot basidiomycete Lentinula edodes is the second most edible mushroom cultivated on the world. This fungus decomposes cell-wall associated macromolecules, is a natural degrader of lignin polymers. The differences in enzyme activities between strains of L. edodes provided useful information about the participation of enzymes in different development stages of the fungus. The effect of lignin on the fungal … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 3 · 28 Apr 2014 · 7,845 accessesView PDF Cite

It can present clinically in two major forms: Acute Otitis Media (AOM) and Otitis Media with Effusion (OME) and it is one of the leading cause of hospital visits and antibiotic prescriptions amongst children and even adults. Antibiotic resistance is a global public … …American Journal of Infectious Diseases, Vol. 9, Issue 1 · 21 Mar 2013 · 7,970 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleStudies on the Seasonal Changes in Antioxidant Enzymes Activity on Differently, Polluted Areas along the Bay of Bengal Employing Perna viridis as an Animal ModelC. Amutha, P. SubramanianAntioxidants are the innate or acquired molecules capable of slowing down or preventing the oxidative damage (damage due to reactive oxygen species) that caused by free radicals. The antioxidant enzyme activity in response to season as well as hydrocarbon pollution was attempted. Rayapuram fishing harbor of Chennai (Station-1) is highly oil contaminated with oil sleeks on the surface.

Research ArticleOpen accessEvery word in the titleUse 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
