Application of the kinetic and isotherm models for better understanding of the mechanism of biomineralization process induced by Purpureocillium lilacinum Y3.

Purpureocillium lilacinum can promote the biomineralization of jarosite by secreting extracellular polymeric substances (EPS), but the detailed mechanism is not clear. In this study, the biosynthesis process of jarosite induced by P. lilacinum Y3 and hypha cell surface characterization were investigated.

Traits of Exogenous Species and Indigenous Community Contribute to the Species Colonization and Community Succession.

Introducing exogenous species into an environment is an effective method to strengthen ecological functions. The traits of the exogenous species and the indigenous communities, as well as the resistance and subsequent succession of the community to exogenous species, are not well-understood. Here, three different functional consortia were introduced into two extremely acidic systems, leaching heap (LH) and leaching solution (LS), derived from the Zijin copper mine in China.

Chalcopyrite bioleaching of an leaching system by introducing different functional oxidizers.

Introducing exogenous species to an indigenous microbial community is an effective way to reveal the connections between metabolic processes, ecological function and microbial community structure. Herein, three different functional consortia (ferrous oxidizers, sulfur oxidizers and ferrous/sulfur oxidizers) were added to a natural leaching solution system derived from Zijin copper mine, China. The leaching experiment showed that the copper extraction rate of the community invaded by a sulfur-oxidizing consortium was 50.
