Abstract Production of bacterial cellulose hydrogel and its evaluation as a proton exchange membrane (PEM) was evaluated. Initially, the membranes (BCH) produced by fermentation in 600 mL bioreactor with 300 medium volume, 10% v/v inoculum Komagataeibacter hansenii under static conditions, temperature 30 °C. The bacteria were cultivated Hestrin-Schramm (HS) pH adjustment to 6.6 HCl and/or NaOH. Five culture media evaluated obtain uniformity on surface rapid formation BCH membrane: HS (M1),...
The biotransformation of rice husk ash (RHA) by Fusarium oxysporum to generate silica nanoparticles was carried out using two different commercial growth media: malt-glucose (MG) and malt-glucose-yeast-peptone (MGYP). Biomass production, substrate consumption, organic acids solubilized were measured during RHA biotransformation. Extracellular proteins analyzed SD-PAGE. Silica XRD, zeta potential, SEM, TEM. results showed that the production not directly related solubilization silica....
The exponential growth of electronic waste (e-waste) has raised significant environmental concerns, with projections indicating a surge to 74.7 million metric tons e-waste generated by 2030. Waste printed circuit boards (WPCBs), constituting approximately 10% all e-waste, are particularly intriguing due their high content valuable metals and rare earth elements. However, the presence hazardous elements necessitates sustainable recycling strategies. This review explores innovative approaches...
Resumo A drenagem ácida de mina da mineração carvão é um dos mais graves problemas ambientais que existem atualmente e caracterizada, principalmente, por apresentar elevada acidez, baixo pH expressiva concentração metais tóxicos, como ferro, Mn muitos outros, afetando diretamente mananciais rios. Em busca uma alternativa pudesse melhorar, forma eficiente econômica, os níveis acidez ferro água impactada pela mina, foi desenvolvido adsorvente geopolimérico à base materiais residuais indústria...
Fusarium oxysporum.In this work, an experimental design was used to analyze the influence of process parameters on production extracellular enzymes such as β-glucosidase and peroxidase, their possible effect obtention soluble nanostructured silica from rice husk ash by action fungus oxysporum.Specifically, pH, fermentation time glucose concentration in culture medium were varied.Statistical analysis indicated that synthesis aqueous strongly dependent pH time.Although does not exert a direct...

Initially, the (BC) produced by fermentation in 600 mL bioreactor with 300 medium volume, 10% v/v inoculum Komagataeibacter hansenii under static conditions, temperature 30°C. The bacteria were cultivated Hestrin-Schramm (HS) pH adjustment to 6.6 HCl and/or NaOH. Five culture media evaluated: HS (M1), M1 + green tea extract (M3), mixture extra thyme (M4), glycerin (M5). kinetics...
