A new series of salicylic spiroborate complexes (SSBs) based on N,O-bidentate 2-(tert-cycloalkylamino)-5-(3-(arylamino)acryloyl)thiophene-3-carbonitriles (NO-SSBs) was obtained and characterized. The optical properties of these compounds were studied and compared with those of analogous BF2-based complexes. The geometries and electronic structures of the NO-SSBs in the ground and excited states, especially their key N–B–O link, were revealed using quantum chemical calculations and compared with the experimental data and photophysical characteristics. Hydrolytic dissociation and photodissociation were considered, and the effects of the NO-SSB structure and nature of the solvent on these reactions were established. Biological investigations elucidated the NO-SSBs ability to penetrate living and fixed cells and selectively accumulate in the endoplasmic reticulum (ER) and Golgi complex. Comparison of the NO-SSBs’ characteristics with those of a commercial dye demonstrated the superiority of their properties and prospects for application in the bio-visualization of the ER and Golgi complex.

Bioaugmentation is an effective approach to remediate soils contaminated by polycyclic aromatic hydrocarbons (PAHs), but suffers from unsatisfactory performance in engineering practices, which is hypothetically explained by the complicated interactions between indigenous microbes and introduced degraders. This study isolated a cultivable pyrene degrader (Sphingomonas sp. YT1005) and an active pyrene degrading consortium (Gp16, Streptomyces, Pseudonocardia, Panacagrimonas, Methylotenera and Nitrospira) by magnetic-nanoparticle mediated isolation (MMI) from soils. Pyrene biodegradation was postponed in bioaugmentation with Sphingomonas sp. YT1005, whilst increased by 30.17% by the active pyrene degrading consortium. Pyrene dioxygenase encoding genes (nidA, nidA3 and PAH-RHDα-GP) were enriched in MMI isolates and positively correlated with pyrene degradation efficiency. Pyrene degradation by Sphingomonas sp. YT1005 only followed the phthalate pathway, whereas both phthalate and salicylate pathways were observed in the active pyrene degrading consortium. The results indicated that the uncultivable pyrene degraders were suitable for bioaugmentation, rather than cultivable Sphingomonas sp. YT1005. The negative correlations between Sphingomonas sp. YT1005 and the active-yet-uncultivable pyrene degraders were the underlying mechanisms of bioaugmentation postpone in engineering practices.
