Exploration of Trichoderma reesei as an alternative host for erythritol production.

Background: Erythritol, a natural polyol, is a low-calorie sweetener synthesized by a number of microorganisms, such as Moniliella pollinis. Yet, a widespread use of erythritol is limited by high production costs due to the need for cultivation on glucose-rich substrates. This study explores the potential of using Trichoderma reesei as an alternative host for erythritol production, as this saprotrophic fungus can be cultivated on lignocellulosic biomass residues.

Fast and efficient CRISPR-mediated genome editing in Aureobasidium using Cas9 ribonucleoproteins.

Species of the genus Aureobasidium are ubiquitous, polyextremotolerant, "yeast-like" ascomycetes used for the industrial production of pullulan and other products and as biocontrol agents in agriculture. Their application potential and wide-spread occurrence make Aureobasidium spp. interesting study objects.

Air moisture signals in a stable oxygen isotope chronology of dwarf shrubs from the central Tibetan Plateau.

Background And Aims: Annually resolved biological climate proxies beyond the altitudinal and latitudinal distribution limit of trees are rare. In such regions, several studies have demonstrated that annual growth rings of dwarf shrubs are suitable proxies for palaeoclimatic investigations. In High Asia, the pioneer work of Liang et al.
