The sulfate removal from acid mine drainage (AMD) water (initial concentration: 5301 mg/L) was investigated by precipitation and/or adsorption using calcium hydroxide (Ca(OH)2) and synthetic layered double hydroxide (LDH) of the Mg/Al type. The exclusive use of LDH efficiently removed sulfates (64.2% reduction); however, alteration of its structure was observed due to low pH. The use of Ca(OH)2 in different doses calculated in relation to gypsum stoichiometry allowed to achieve an 86% removal of sulfates. Depending on the equilibrium pH, gypsum or ettringite were the main identified phases. The two-step removal, involving the use of Ca(OH)2 followed by LDH, was less efficient than the use of the Ca(OH)2/LDH mixture when the stoichiometric amount of Ca(OH)2 in relation to gypsum was applied. The application of mixture resulted in a fast pH increase, which prevented destruction of the LDH structure. Most importantly, the use of mixture significantly reduced the sludge volume and enhanced its settling velocity.

Peroxiredoxin (Prx) is an important peroxidase that can protect organisms against various oxidative stresses. In this study, a member of Prx family, designated LvPrx, was cloned fromLitopenaeus vannamei. Sequence and phylogenetic analyses indicated that LvPrx belongs to the 2-Cys Prx (Prx IV) isoform. The recombinant LvPrx protein was constructed and expressed inEscherichia coli, and the purified LvPrx proteins were shown to reduce H2O2in vitro in the presence of dithiothreitol, indicating that LvPrx is a functional peroxiredoxin. Using qRT-PCR, the mRNA expression levels of LvPrx were determined in the haemocytes ofL. vannameiat different stages after being challenged with WSSV and TSV at different doses. The results showed that the expression levels of LvPrx were significantly up-regulated () during 4-24 h after both WSSV and TSV challenge, suggesting that LvPrx may participate in the shrimp’s immune response to viral infection.
