Chitosanase Activity

The chitinase and chitosanase activities after β-D-glucan nanoparticle (GNP) application turmeric plants (leaves and rhizomes) were measured. Foliar spray of GNP (0.1%, w/v) elicited marked an increase in the activity levels of chitinases and chitosanases. Such a growth of enzyme activities was enhanced by subsequent spraying GNP on turmeric leaves at regular intervals. Application of β-D-glucan nanoparticles enhanced the level of defense related enzymes in leaves and rhizomes, which correlated well with new isoforms of the enzymes. Qualitative differences in isoforms of these defense enzymes were investigated during the hereby time-course study. In general, the expression of chitinase activity was comparatively lower in rhizomes than in leaves. Chitinase and chitosanase activity reached maximum values during the 7th month. Exploiting the nanoparticle (derived from natural polysaccharide) potential may refer to induce defense enzymes that may diminish the use of toxic chemicals for disease control. Thus the use of nanoparticles could be proposed as an alternative, non-conventional and ecologically friendly approach for plant protection and hence for sustainable agriculture.

Time Course Study

Pseudomonas facilis and Pseudomonasspp., isolated on the basis of its ability to grow on polycyclic aromatic hydrocarbon, was assayed for biosurfactant production (BP) potentials by measuring the surface tension (ST) of the culture supernatant at different time intervals. The strains in three levels of initial inoculum size (OD600 nm = 0.5, 1, 1.5) were added to medium to determine if bacterial inoculum size affects solubilization of phenanthrene (PHE).The result showed that although the two strains reduced the mean ST to less than 34.12 mN m−1 at the end of day 6, mean solubilization activity of PHE reached 77.05 mg L−1 on the sixth day. There was a significant increase in BP over time (P = 0.008); reaching its peak, 157.84 mg L−1, at the end of the sixth day. Mean solubilization activity of PHE was not significantly different for the two strains (P = 0.216). The time-course study revealed that the ST reduction and BP potential was enhanced as inoculation size increased, leading to higher PHE solubility during the incubation time. However, the trend of increase in PHE solubility was not totally in the same way to cell growth and BP. It may be suggested that more bacterial density needs to be inoculated for practical application of effective bioremediation.
