Mural paintings in Carmona (Spain), Herberstein (Austria) and Greene (Germany), showing visible deterioration by microorganisms, were sampled to investigate the biodiversity of the heterotrophic bacteria present. Four hundred twenty-eight bacterial strains were isolated from which 385 were characterized by fatty acid methyl ester analysis (FAME). The isolates were grouped into 41 clusters on th...

Some marine microorganisms can degrade oil pollutants by using them as their sole carbon and energy sources. Members of this heterogenic group are called hydrocarbonoclastic bacteria. However, an unestimated number of hydrocarbonoclastic marine bacteria have not yet been characterized. In this context, a microcosm study was carried out, simulating a marine environment contaminated with oil in U...

Marine oil spill pollution was one of the factors affecting marine ecology northeastern South China Sea (nSCS). The submarine produced after had a long-term impact on microbial community in sediment. In this study, 16S rRNA genes high-throughput sequencing and quantitative PCR were used to study composition distribution bacterial communities deep-sea sediments; meanwhile, petroleum hydrocarbon ...

Transaminases have arisen as one of the main biocatalysts for amine production but despite their many advantages, stability is still a concern widespread application. One reasons instability need to use an excess amino donor when trying synthesise amines with unfavourable equilibria. To circumvent this, recycling systems donor, such acid dehydrogenases or aldolases, proved useful push equilibri...

Biosurfactants are structurally diverse surface-active agents mostly produced by various genera of bacteria, yeast and filamentous fungi that have a wide range applications properties. They surface interfacial activity, temperature pH tolerance, biodegradability, low toxicity anti-adhesive property. Their production was reported to be affected temperature, PH, aeration agitation, salt concentra...

Bilge wastewater is a high strength, typically saline wastewater, originating from operation of ships. In this study, the treatment real bilge was tested using pure isolated aerobic strains and mixed cultures (aerobic anaerobic). The Chemical Oxygen Demand (COD) ecotoxicity decrease were monitored over time, while microbial dynamics alterations in also recorded. Pseudodonghicola xiamenensis, Ha...
