BACKGROUND Non-conventional yeasts present a huge, yet barely exploited, resource of yeast biodiversity for industrial applications. This presents a great opportunity to explore alternative ethanol-fermenting yeasts that are more adapted to some of the stress factors present in the harsh environmental conditions in second-generation (2G) bioethanol fermentation. Extremely tolerant yeast species...

Four new species of Anomala Samouelle and two new species of Callistethus Blanchard (Coleoptera: Scarabaeidae: Rutelinae: Anomalini) from Costa Rica are described: A. aglaos new species, A. estrella new species, A. inbio new species, A. pincelada new species, C. ruteloides new species, and C. yalizo new species. A distribution map of each species is given and the male genitalia (aedeagus and en...

A marked enhancement in the production of cell-bound phytase in Pichia anomala was achieved in cyclic fed batch fermentation (47333 UL -1 ) in comparison with that in batch (11569 UL -1 ) and fixed volume fed batch (36911 UL -1 ) fermentations in cane molasses medium. Phytase productivity was sustainable in cyclic fed batch fermentation over seven days, and therefore, this mode of fed batch fer...

Anomala eucoma Bates, 1888 is redescribed and a lectotype from Guatemala is designated. Three new species from Costa Rica, A. flavacoma new species, A. megaparamera new species, and A. pseudoeucoma new species, are described, and a distribution map is given. The internal sac (endophallus) of the species covered is illustrated, and its use in separating closely related species in this region is ...
