Role of chitinase expression in the virulence of Lecanicillium lecanii against citrus black aphid (Toxoptera aurantii).

Chitinase plays a vital role in the virulence of entomopathogenic fungi (EPF) when it infects host insects. We used gene recombination technology to express chitinase of three strains of Lecanicillium lecanii: Vl6063, V3450, and Vp28. The ORF of ChitVl6063, ChitV3450 and ChitVp28 were inserted into the fungal expression vector pBARGPE-1, which contained strong promoter and terminator, respectively, to construct a chitinase overpressing plasmid, then transformed the wild-type strain with blastospore transformation method.

Utilisation of persistent chemical pollutant incorporating with nanoparticles to modify the properties of geopolymer and cement concrete.

The majority of industrial products are identified as persistent organic pollutants after their date of expiry, which is highly harmful to the ecosystem and human health and also going to be banned around the world. Paint latex is one of those pollutants which become a hazardous waste material after stocking for a long time. Approximately 20% of color paints do not get used for their desired purpose after getting sold out and end up in a landfill.
