Bacterial diversity in traditional Jiaozi and sourdough revealed by high-throughput sequencing of 16S rRNA amplicons

Abstract: The bacterial communities of 4 dough fermentation starter samples, including Jiaozi A and D and sourdough B4 and B5 selected from Henan, Jiangsu, and Liaoning province of China were compared by high-throughput sequencing of 16S rRNA genes. The highest number of operational taxonomic units (OTUs) was found for the genus Acetobacter in Jiaozi A, but only OTUs adapted to dough conditions after 8 h (A8) and 24 h (A24) of fermentation using Jiaozi A as dough starter. Members belonging to the genus Pediococcus appeared to dominate in Jiaozi D, especially in the dough (D24) fermented for 24 h started by Jiaozi D. The genus Lactobacillus dominated in sourdough B5, A8, and A24. Weissella was the predominant genus in sourdough B4, and members of the genera Leuconostoc and Lactococcus were also identified.

Conferring supramolecular guanosine gel nanofiber with ZIF-67 for high-performance oxygen reduction catalysis in rechargeable zinc–air batteries

Abstract: Nanostructured gels have emerged as a unique material platform for energy-related applications and have been mainly focused on polymer gels in recent years. We developed a coordination-driven hierarchical assembly strategy for the general exploration of robustness supramolecular gel (SMG) materials as metal-organic framework (MOF) supports for further development of high efficiency oxygen reduction reaction electrocatalysts for rechargeable Zn–air batteries. As the first example of SMG/MOF composites, guanosine SMG (GSMG) fibres were modified by terpyridine ligands, cross-linked by Zn (II), and then anchored in-situwith ZIF-67 polyhedra to produce a special ZIF-67/Zn-GSMG heterostructure enriched in heteroatoms (B, N, C, Co, and Zn) and with a continuous rigid skeleton. Pyrolysis yielded cobalt-embedded porous carbon polyhedra/B,N dual-doped carbon nanofibers with superior oxygen reduction reaction activity, showing an exceptional potential for applications in rechargeable Zn–air batteries. The present work provides a new material platform for promising future design of functional multicomponent composites.
