“…The filter media surface consisted of biofilms of a pure culture Pseudomonas citronellolis YAIP521 purified from a wastewater treatment system at Hsinchu Science‐based Industrial Park (HSIP) in Taiwan and were inoculated before use. GenBank BLAST analysis of 16S rRNA gene (http://www.ncbi.nlm.nih.gov) of YAIP521, based on the sequence of a ∼1400‐bp fragment revealed that the accession number, percentage of similarity and E values for the matching score (indicated in parentheses) is Pseudomonas citronellolis strain TERIDB26 (AF530073.1, 99%, 0.0) , …”

BACKGROUND: A bench-scale biotrickling filter coupled with Pseudomonas citronellolis YAIP521-immobilized polyvinyl alcohol (PVA)/alginate beads was developed for kinetic analysis of microbial removal of isopropyl alcohol (IPA), an organic solvent widely used for fabricating wafers and printed circuit boards. RESULTS:Response surface methodology (RSM) showed that the optimal ratio of PVA to alginate was 7.5 g to 0.8 g. More than 95% of IPA removal could be achieved at an inlet concentration of 220 ± 34 ppm (w/w) under short residency time. System stability decreased under high IPA concentration and intermittent shock-loading conditions but increased when using cell-immobilized beads because the buffer effect limited the adverse impacts of high IPA concentrations on microorganisms, and the system gradually stabilized with IPA removal efficiency as high as 95%. Nevertheless, qPCR indicated that intermittent shock-loading decreased the biomass in the beads. CONCLUSION:The experimental results showed that the biotrickling filter system developed effectively diminishes the inhibitory effects of elevated IPA concentration on microbial growth, thereby solving the problem of high IPA loading often encountered in the electronic high-tech industries. The design of the system along with the population dynamics and reaction kinetics provide superior information to ensure the success of the biotrickling filter system.

Biotechnology uses substances, materials or extracts derived from living cells, employing 22 million Europeans in a € 1.5 Tn endeavour, being the premier global economic growth opportunity this century. Significant advances have been made in red biotechnology using pharmaceutically and medically relevant applications, green biotechnology developing agricultural and environmental tools and white biotechnology serving industrial scale uses, frequently as process feedstocks. Red biotechnology has delivered dramatic improvements in controlling human disease, from antibiotics to overcome bacterial infections to anti-HIV/AIDS pharmaceuticals such as azidothymidine (AZT), anti-malarial compounds and novel vaccines saving millions of lives. Green biotechnology has dramatically increased food production through Agrobacterium and biolistic genetic modifications for the development of 'Golden Rice', pathogen resistant crops expressing crystal toxin genes, drought resistance and cold tolerance to extend growth range. The burgeoning area of white biotechnology has delivered bio-plastics, low temperature enzyme detergents and a host of feedstock materials for industrial processes such as modified starches, without which our everyday lives would be much more complex. Biotechnological applications can bridge these categories, by modifying energy crops properties, or analysing circulating nucleic acid elements, bringing benefits for all, through increased food production, supporting climate change adaptation and the low carbon economy, or novel diagnostics impacting on personalized medicine and genetic disease. Cross-cutting technologies such as PCR, novel sequencing tools, bioinformatics, transcriptomics and epigenetics are in the vanguard of biotechnological progress leading to an ever-increasing breadth of applications. Biotechnology will deliver solutions to unimagined problems, providing food security, health and well-being to mankind for centuries to come.
