Synthesis, antibacterial properties and bioinformatics computational analyses of novel 8-hydroxyquinoline derivatives.

New heterocyclic derivatives of were prepared and screened as antimicrobial agents. Chemical structures were elucidated and confirmed using different spectroscopic methods such as elemental analysis data, Infrared, Nuclear Magnetic Resonance Spectroscopy. In order to explore their potential biological activity, the " antibacterial activity was investigated against and .

Optimization of composition of media for the production of extracellular glucoamylase by Candida guilliermendii.

The combined effects of macronutrients of media on glucoamylase production by Candida guilliermendii were studied using Design Of Experiment (DOE). A 2(P-k) factorial design was chosen to explain fifteen medium constituents: pH, Starch, Sucrose, Yeast extract, Peptone, NH4Cl (NH4)2HPO4, NH4NO3, CH4NO2 (NH4)2SO4, CaCl2, MnCl2, FeCl2, ZnCl2 and MgCl2 and analyse the results. This procedure limited the number of actual experiments performed while allowing for possible interactions between components.
