FEBS Open Bio, EarlyView.Enzymes of the 2‐hydroxyacyl‐CoA lyase group catalyze the condensation of formyl‐CoA with aldehydes or ketones. Thus, by structural adaptation of active sites, practically any pharmaceutically and industrially important 2‐hydroxyacid could be biotechnologically synthesized. Combining crystal structure analysis, active site mutations and kinetic assays,

Influence of physical and biological processes on the seasonal cycle of biogenic flux in the equatorial Indian Ocean [PDF]
Biogeosciences, 2013 Seasonal cycle of biogenic fluxes obtained from sediment trap at two locations 5°24' N, 86°46' E (southern Bay of Bengal trap; SBBT) and 3°34' N, 77°46' E (equatorial Indian Ocean trap; EIOT) within the equatorial Indian Ocean (EIO) were examined to ...

New organic matter degradation proxies: Valid in lake systems? [PDF]
, 2004 We determined concentrations and diagenetic state of organic matter in two cores from Lake Zug, Switzerland. To obtain a general picture of organic matter decay in the lake, we measured bulk parameters such as total organic carbon, total nitrogen, and ...

Sediment traps with guiding channel and hybrid check dams improve controlled sediment retention [PDF]
Natural Hazards and Earth System Sciences, 2018 Sediment traps with partially open check dams are crucial elements for flood protection in alpine regions. The trapping of sediment is necessary when intense sediment transport occurs during floods that may endanger urban areas at downstream river ...

Analisis Aplikasi Kantong Lumpur pada Sungai Sebagai Upaya Pengendalian Sedimentasi Waduk
Media Komunikasi Teknik Sipil, 2021 Sedimentasi waduk dapat diatasi dengan mengurangi jumlah sedimen yang masuk ke waduk, dengan membangun check dam. Akan tetapi check dam lebih banyak mengendapkan muatan sedimen kasar daripada muatan sedimen halus.
