The research presented here is aimed at exploring the effect of DTT on the in vitro fibril formation of hen egg-white lysozymes with four disulfide bonds. In this work, we specifically addressed the effect of DTT concentration under different incubation temperatures on the hen lysozyme structure and fibril formation, the effect of addition of DTT at later time points on the amyloid fibrillization of hen lysozymes, and the effect of concentration ratio between reduced and oxidized forms of DTT on the fibril formation of lysozymes.

The influences of environmental factors on the abiotic methylation were studied. The biggest production of methylmercury was found after 2 days of incubation in presence of FA. The rate of production of methylmercury depends upon temperature. In presence of FA from sediment, the biggest production of methylmercury was found under 40℃. In presence of FA from soil, production rate increases with temperature. The biggest production of methylmercury was found when solution pH was 2 and 4 in presence of FA from sediment and soil, respectively. Increase in concentrations of inorganic mercury and FA solution causes an increase in the production of methylmercury. Under irradiation with ultraviolet ray, blacklight lamp as well as natural light, methylation is stimulated, especial for irradiation of ultraviolet light.
