Methylation of arsenic by single-species and soil-derived microbial cultures

Karen Elda Viacava Romo

Arsenic (As) is simultaneously a ubiquitous and a toxic element. Arsenic is subject to bio-transformations catalyzed by microorganisms constituting the As biogeochemical cycle. The primordial Earth was devoid of oxygen, exposing life to the highly mobile a ...

Mechanism(s) of electron transfer and metabolic changes during iron reduction by Clostridium acetobutylicum

Cornelia List

Microorganisms catalyze many of the redox transformations driving the iron cycle in the geosphere. For instance, iron cycling includes the reduction of solid-phase and soluble ferric iron (Fe(III)) to ferrous iron (Fe(II)). However, in order to reduce soli ...

Identifying gene function and module connections by the integration of multispecies expression compendia

Johan Auwerx, Kristina Schoonjans, Stephan Morgenthaler, Fabrice David, Hao Li, Maroun Bou Sleiman, Elena Katsyuba, Wen Gao, Daria Rukina, Qingyao Huang, Yang Li, Changmyung Oh, Andrea Komljenovic

The functions of many eukaryotic genes are still poorly understood. Here, we developed and validated a new method, termed GeneBridge, which is based on two linked approaches to impute gene function and bridge genes with biological processes. First, Gene-Mo ...

Diving into the dynamics of product evolution : analyzing technological discontinuities during the era of incremental change and cognitive convergence on a dominant design

Olivier Waeber

Three distinct stages describe the technological evolution of a product over time: ferment, convergence on a dominant design and an era of incremental change. Until recently, the era of incremental change has been characterized as stable and one that invol ...

Comparison of liquid hot water (LHW) and high boiling alcohol/water (HBAW) pretreatments for improving enzymatic saccharification of cellulose in bamboo

Li Chen, Li Shuai, Jing Liu, Meng Li, Yubo Zhao

Liquid hot water (LHW) and high-boiling point alcohol/water (HBAW) pretreatments were compared to improve enzymatic saccharification of cellulose in moso bamboo. When pretreatments were conducted at 200 degrees C for 40 min, HBAW (20% (v/v) 1,4- butanediol ...
