Abstract There is significant potential for employing algae in tertiary wastewater treatment, however, little known about the contribution of algae-bacteria synergy toward treatment performance. This study demonstrates three winery samples. Two strains green algae, Auxenochlorella protothecoides and Chlorella sorokiniana were tested each removed > 90% nitrogen, 50% phosphate, 100% acetic acid wastewater. Both grew significantly faster on wastewaters compared to growth minimal media....
Chlorella minutissima was co-cultured with Escherichia coli in airlift reactors under mixotrophic conditions (glucose, glycerol, and acetate substrates) to determine possible effects of bacterial contamination on algal biofuel production. It hypothesized that E. would compete C. for nutrients, displacing biomass. However, grew more rapidly higher densities the presence coli, suggesting a symbiotic relationship between organisms. At an initial 1% substrate concentration, co-culture produced...
Abstract Wastewater treatment is an energy‐intensive process and a net emitter of greenhouse gas emissions. A large fraction these emissions due to intensive aeration aerobic bacteria facilitate break‐down organic compounds. Algae can generate dissolved oxygen at levels in excess saturation, therefore hold the potential partially displace or complement mechanical wastewater processes. The objective this study was develop internally consistent experimental modeling approach test hypothesis...
Algae are a diverse group of aquatic organisms and have potential to produce renewable biofuel via hydrothermal liquefaction (HTL). This study investigated the effects reaction environments on biocrude production from “Tetraselmis sp.” algae strain by HTL process using red mud (RM) based catalyst. The inert (N2), ethylene (C2H4), reducing (10% H2/90% N2), oxidizing O2/90% N2) were applied non-catalytic as well catalytic treatments with two forms RM catalysts: reduced at 500 °C (RRM)...
ABSTRACT Lipid productivity and fatty acid composition are important metrics for the production of high quality biodiesel from algae. Our previous results showed that co‐culturing green alga Chlorella minutissima with Escherichia coli under high‐substrate mixotrophic conditions enhanced both culture growth crude lipid content. To investigate further, we analyzed neutral content axenic cultures co‐cultures produced autotrophic conditions. We found C. E. substrate (10 g/L) increased 1.9‐ to...
Rendered meat byproducts are important feedstocks for pet food formulas, esterified biodiesels and other bioproducts. However, with high water contents currently not attractive rendering due to the need evaporate resulting protein "stick" water. Consequently, many wet byproducts, like poultry dissolved air flotation (DAF) solids, land applied, wasting a potential resource, causing malodor nearby communities. Herein, we present process where stick produced from hydrolyzers is sold as...
Bacillus velezensis FZB42 is a prominent plant growth-promoting rhizobacterium and biocontrol agent known for producing wide array of antimicrobial compounds. The capability to genetically manipulate this strain would facilitate understanding its metabolism enhancing sustainable agriculture applications. In study, we report the first successful implementation high-efficiency CRISPR-Cas9 genome editing in B. FZB42, enabling targeted genetic modifications gain insights into growth-promotion...
