“…Several reports showed that pH optima of GOD varied from 3.5 to 7 [12,20]. Thus, GOD from most fungi generally had pH optima in the acidic to neutral range such as A. niger [46], P. amagasakiense [44] and P. notatum [20]. In contrast, the GOD obtained from P. funiculosum 433 and P. canescens slightly showed alkaline pH optima of 6-8.6 [47].…”

This study was carried out to evaluate the in vitro and in vivo antifungal efficiency of Aspergillus tubingensis CTM 507 glucose oxidase (GOD) against plant pathogenic fungi. GOD displayed a wide inhibitory spectrum toward different fungi at a concentration of 20 AU. The GOD had a strong inhibitor effect on mycelia growth and spore germination of Pythium ultimum. Interestingly, the GOD exhibited a potent in vivo antifungal effect against P. ultimum responsible for potato plants disease. The antifungal GOD was purified 13-fold with 27 % yield and a specific activity of 3435 U/mg. The relative molecular mass of the GOD was 180 kDa by sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE). The GOD activity was optimum at pH 4.5 and 60 °C. It was found to be stable over a large pH range (3-9). It also displayed a marked thermostability with a 50-min half-life at 65 °C. The 10 residues of the N-terminal sequence of the purified GOD (S-K-G-S-A-V-T-T-P-D) showed no homology to the other reported GOD, identifying a novel GOD. FTIR spectroscopic analysis revealed the presence of C-O and C=O groups corresponding to a D-glucono-lactone. The findings indicated that GOD is the first A. tubingensis-produced fungicide ever reported to exhibit such promising biological properties. It could become a natural alternative to synthetic fungicides to control certain important plant microbial diseases.

“…A total of 100 fractions were collected after application of 1.5 mL of desalted enzyme. Sephadex G-200 was used to elute the desired enzyme having highest specific activity (Sukhacheva et al 2007). All the fractions collected were subjected to enzyme analysis and protein determination (Worthington 1988).…”
