The release of organic pollutants in nature with different forms are treat to the environment and living organism. Particularly, monitoring of the presence of polyaromatic hydrocarbons (PAH) are of great interest due to the fact that they accumulate in soil, water-resources and living organisms and can contaminate food as well. Sensitive and selective detection of PAHs are critical because of the fact that strict regulations governed by national and/international organizations may require different firm value for minimum-allowed concentrations for each PAHs in addition to the total allowed PAHs concentrations. Therefore, analytical and bioanalytical techniques based on different principles have been developed to reach optimized sensitivity and selectivity. Among these techniques, mass spectroscopy coupled chromatographic methods including liquid chromatography (LC) and gas chromatography (GC), and those coupled with spectroscopy are in use to monitor the level and type of the PAH for about 90 years. In addition to these, in last 50 years, biosensors were introduced in detection of PAHs. Particularly, whole-cell based (e.g. engineered yeast cells) and affinity-based (e.g. ELISA) biosensors are currently hot research topics for their simplicity and versatility. In this review, for PAHs detection, historical perspectives, status and outlook along with suggestions are discussed.

Unannounced to prescribers or patients, Novo Nordisk have changed the manufacturing process of their human insulins from enzymatic modification of pig insulin (emp) to direct biosynthesis of genetically engineered yeast cells (pyr). The preservative for Human Actrapid insulin has also been changed from phenol to meta-cresol. No warning of this change was sent to pharmacists, doctors, diabetes specialists or patients.

In this study, in order to directly and efficiently convert inulin into a single-cell oil (SCO), an <i>INU1</i> gene encoding inulinase from<b><i></i></b> <i>Kluyveromyces marxianus</i> was integrated into the genomic DNA and actively expressed in an SCO producer <i>Aureobasidium</i> <i>melanogenum</i> P10. The transformant API41 obtained produced 28.5 U/mL of inulinase and its wild-type strain P10 yielded only 8.62 U/mL. Most (97.5%) of the inulinase produced by the transformant API41 was secreted into the culture. During a 10-L fermentation, 66.2% (w/w) lipid in the yeast cells of the transformant API41 and 14.38 g/L of cell dry weight were attained from inulin of 80.0 g/L within 120 h, high inulinase activity (23.7 U/mL) was also produced within 72 h, and the added inulin was actively hydrolyzed. This confirmed that the genetically engineered yeast of <i>A. melanogenum</i> P10 is suitable for direct production of lipids from inulin. The lipids produced could be used as feedstocks for biodiesel production.
