Chitinases have the ability of chitin digestion that constitutes a main compound of the cell wall in many of the phytopathogens such as fungi. In the following investigation, a novel chitinase with antifungal activity was characterized from a native Serratia marcescens B4A. Partially purified enzyme had an apparent molecular mass of 54 kDa. It indicated an optimum activity in pH 5 at 45°C. Enzy...

Generally, the propagules survive depending upon environmental conditions, such as humidity, temperature cleanness. aim of this research work was to detect outdoor at city Morelia, Mich, México. So far similar study is not reported city. For purpose, sam...

Benzoylpyridine and nitro benzoic acid hydrazides were used to examine novel Schiff base Co(II), Mn(II), Fe(II), Cu(II) complexes. Elemental analysis, molar conductance, magnetic measurements other methods that like FT-IR, UV–Vis 1H NMR studies have been deduce the nature of bonding structure these These revealed Fe(II) coordinated by four donor atoms in all Free radical scavenging activity was...
