Increased removal of Reactive Blue 72 and 13 acidic textile dyes by Penicillium ochrochloron fungus isolated from acidic mine drainage

Talaromyces aculeatus from acidic environment as a new fungal biosorbent for removal of some reactive textile dyes

“…Thus the top removal yield reached at 150 rpm so this optimum parameter was studied for the further experiments ( Figure 3). In general, the enhancement of biosorption yield with increasing agitation rates up to 150 rpm was attributed to an enhanced mass transfer rate [19].…”

“…For all textile dyes in this study, the biosorption percentages of fungal biosorbent decreased with enhancing pH (after pH 2), indicating the important forces between dye anion molecules and the dye binding regions of the positively charged bioadsorbent surface. In other words, the negative charge density on the biosorbent surface enhanced when the pH was increased; therefore biosorption was decreased [17][18][19].…”

“…This result indicates that biosorptions of dyes are an endothermic except RB 72, which is further demonstrated in section 3.9. According to the study of Aytar and co-workers, the biosorption capacity of the biosorbent of P. ochrochloron AMDB-12 isolated from another metal mine drainage was similarly increased with an enhancement in temperature from 20 to 40˚C [19].…”

“…could produce a number of commercial enzymes including cellulases, amylases and chitinases [15,16] and it represents a fungal biomass potential source for use in biosorptive technology. These organisms exhibiting tolerance to strong acidic conditions have important potential for use in applications of biotechnology, including acidic textile dye wastewater decolorization [3,[17][18][19].…”

Culture‐dependent diversity of boron‐tolerant bacteria from boron mine tailings pond and solid wastes

“…The microorganisms both need these harsh conditions to grow and have tolerance these extreme environments (Satyanarayana et al , ). Studies on extremophile microorganisms are important because of identification of microbial diversity and biotechnology applications (Satyanarayana et al , ; Aytar et al , ; ). The microbial diversity analyses can be performed using culture‐dependent and/or ‐independent methods.…”
