PRODUCTION AND OPTIMIZATION OF EXTRACELLULAR XYLANASE ACTIVITY FROM A THERMOPHILIC ACTINOMYCETE ISOLATED FROM POULTRY COMPOST (EAST- ALGERIA)
Journal ID : ALS-19-09-2022-5644; Total View : 227; Author : Habbeche Amina, Haberra Soumaya, Kerouaz Bilal, Saoudi Boudjema, Ladjama Ali,
Abstract : From 32 isolates of actinomycetes isolated from poultry compost in Annaba (East Area Algeria), three autochthones strains Cpt20, Cpt8, Cpt29 screened for their ability of producing thermostable xylanase activities based on the diameter of the clear zone formation in birchwood xylan agar plates. One of them, as Actinomadura keratinilytica Cpt20 produced high amount of extracellular xylanases, this strain was selected and optimized for xylanase enzyme produced in liquid state fermentation. Consequently, for commercial applications, it is advisable to develop processes production starting from inexpensive substrates. The presence of wheat bran as a carbon source in the medium induced the highest production of xylanase (30.64IU/ml). This result is particulary valuable because the other substrates are more expensive. Among all the organic and inorganic sources of nitrogen tested in the study, peptone was found to be the best in stimulating xylanase produced by Actinomadura keratinilytica Cpt20. Optimum pH and temperature for xylanase activity were found to be 8.5 and 45°C after 72h of incubation. After optimization of various production parameters, an increase of nearly 2-fold in xylanase production was achieved. The enzyme has an optimal temperature at 70°C and the half-life of the xylanase at 75°C was 30min.

Studying gut microbiome in type-2-diabetes patients: A mini review
Journal ID : ALS-16-09-2022-5643; Total View : 121; Author : Varsha Singh,
Abstract : Type 2 diabetes mellitus (T2D) is a metabolic condition finding disparity in blood glucose levels, change in lipid profile, along with hypertension. An individual’s genetic profile also plays an important role towards developing a high risk of T2D including diet rich in high fat, and a sedentary lifestyle. Over the decade there has been rise in studies showing fast evolution of the gut microbiome which changes the intestinal barrier function, associated metabolism and signal transduction pathways and further influence insulin resistance mechanisms in the gut and the pancreas. Microbes in the gut regulate the host mechanism by interacting with various intestinal receptors which leads to influence on the heart, lungs and liver. Other environmental induced components also cause a shift in the host metabolism of the T2D individuals such as diet, antibiotics, diabetes specific medication, steroids which alter the gut microbiota of the host. However, the microbiome hence influences majority of the processes in food assimilation, but the exact mechanism of action remains unknown. Hence, special attention should remain in knowing the relationship between the gut microbiome and T2D metabolism regulation to open new avenues for research, discussion and clinically manifesting the maintenance of the same.
