Contamination of heavy metals has been a serious environmental problem due to increasing anthropogenic activities such as mining, smelting, livestock, landfills, waste dumps, and agriculture. Bioleaching experiments were conducted using native Bacillus cereus MAMPE19 BCG, isolated characterized from previous research, test removal arsenic (As) actual mining waste. Mineralogical characterization...

A comparison was studied for non-treated and pretreated corn stover with dilute alkaline peroxide and dilute acid treatment respectively for bioethanol production by simultaneous saccharification and fermentation (SSF) process in a continuous stirred batch bioreactor using fungi Aspergillus oryzae. The optimum parameters for bioethanol fermentation were: time, 48 h; pH, 6.0; temperature, 50oC; ...

: Endogenous dermal stem cells (DSCs) reside in the adult hair follicle mesenchyme and can be isolated and grown in vitro as self-renewing colonies called skin-derived precursors (SKPs). Following transplantation into skin, SKPs can generate new dermis and reconstitute the dermal papilla and connective tissue sheath, suggesting they could have important therapeutic value for the treatment of sk...

This work presents the development of an array of bioreactors where finely controlled stirring is provided at the microliter scale (100-300 mul). The microliter-bioreactor array is useful for performing protocol optimization in up to 96 parallel experiments of hematopoietic stem cell (HSC) cultures. Exploring a wide range of experimental conditions at the microliter scale minimizes cost and lab...

Viral vectors facilitate the delivery of genetic material to living cells for potential treatment multiple diseases. With recent regulatory approvals, rapid growth in demand viral vector-based products highlights need proven, scalable manufacturing solutions that can fully meet this and ultimately increase availability treatments. Pall’s AllegroTM STR stirred-tank bioreactor addresses scalabili...
