Mines, like other subterranean environments, have ecological conditions which allow the thriving of microorganisms. Prokaryotes and fungi are common inhabitants mines, developing a metabolism suitable for growing in such inhospitable environments. The mine Lousal, Portugal, is an interesting site study microorganisms present their galleries. Aerobiological studies resulted isolation Pseudomonas...

Biodegradable aliphatic random copolyesters poly(butylene succinate-co-butylene adipate), PBSA and poly(butylene succinate-co-butylene azelate), PBSAz were synthesized from 1,4 butane diol, succinic acid and adipic acid/azelaic acid through direct melt polycondensation with Titanium Tetra isopropoxide (TTiPO) as a catalyst. These polyesters were characterized by Viscosity measurements, 1H NMR s...

Indoor mold growth has recently become a concern in the legal world in regards to insurance litigation. Hazardous mold exposure to humans has been linked to many acute and chronic adverse health effects including death. As it grows, mold produces several types of primary and secondary metabolites, including microbial volatile organic compounds (MVOCs). Microbial volatile organic compound emissi...

Enzyme cocktails can alter the lignin and hemicellulose content in wood cell walls, improving bleaching process during pulp production offsetting need for toxic chemicals. In this study, brown was biobleached with a mixture of crude fungal extracts rich xylanase laccase, respectively produced from Aspergillus tamarii Kita Trametes versicolor on waste materials. The optimal conditions biobleachi...
