Preparation of β-d-glucan nanoparticles and its antifungal activity

β-d-Glucan nanoparticle pre-treatment induce resistance against Pythium aphanidermatum infection in turmeric

“…Hence, the selection of nanomaterial for application in the field may be critical as materials which are non-toxic, biocompatible and biodegradable are desirable. Nanoparticles prepared from biopolymers or natural sources possess advantages such as availability from replenishable agricultural resources, biocompatibility, as described earlier [6]. The rhizomes of cultivar Erode local were soaked in GNP (0.1%, w/v in sterile distilled water) solution and kept in a rotary shaker (50 rpm min −1 ) for 1 h, shade dried and used for pathogen inoculation.…”

Exocellular (1→6)-β-D-Glucan (Lasiodiplodan): Carboxymethylation, Thermal Behavior, Antioxidant and Antimicrobial Activity

“…This can be observed from the high intensity of such peaks. Similarly, Anusuya and Sathiyabama (2014) observed three peaks (23.2°, 32.5°, 46° at 2θ) in β-glucan nanoparticle samples, which were attributed to a crystalline nature. The peaks observed at 21.1°, 23.8° (2θ) were more pronounced in the LAS-C sample, which suggests that the introduction of carboxymethyl groups in the native macromolecule may have contributed to some increase in its degree of crystallinity.…”

Foliar application of β-d-glucan nanoparticles to control rhizome rot disease of turmeric

“…Based on our previous studies on in vitro inhibition of mycelial growth of P. aphanidermatum (the causal agent of rhizome rot disease of turmeric) by ␤-glucan nanoparticles [38], they were tested for its efficacy against rhizome rot disease in turmeric plants under glass house condition. Based on the preliminary work, the optimum concentration of GNPs for elicitation of defense was identified as 0.1% (w/v) (data not shown).…”

“…GNPs from ␤-glucan were prepared as described earlier [38]. Rhizomes were thoroughly washed with running tap water thrice followed by glass distilled water; surface sterilized by immersion in sodium hypochlorite 0.001% (v/v) solution for 15 min followed by several rinses of sterile distilled water.…”
