“…Trichosporonales consists of a diverse group of members involved in fermentation processes and biotransformation of biarylic compounds (Takashima et al 2019 ; Martínez-Herrera et al 2021 ). Saccharomycetales, a common group in maize, were only present in the MRI sample (Sun et al 2019 ). Members of Saccharomycetales such as Schwanniomyces occidentalis , Saccharomyces cerevisiae , and Candida are responsible for the fermentation of sugars (Johnson and Echavarri-Erasun 2011 ).…”

There is a need to profile microorganisms which exist pre-and-post-production of umqombothi, to understand its microbial diversity and the interactions which subsequently influence the final product. Thus, this study sought to determine the relative microbial abundance in umqombothi and predict the functional pathways of bacterial and fungal microbiota present. Full-length bacterial 16S rRNA and internal transcribed spacer (ITS) gene sequencing using PacBio single-molecule, real-time (SMRT) technology was used to assess the microbial compositions. PICRUSt2 was adopted to infer microbial functional differences. A mixture of harmful and beneficial microorganisms was observed in all samples. The microbial diversity differed significantly between the mixed raw ingredients (MRI), customary beer brew (CB), and optimised beer brew (OPB). The highest bacterial species diversity was observed in the MRI, while the highest fungal species diversity was observed in the OPB. The dominant bacterial species in the MRI, CB, and OPB were Kosakonia cowanii, Apilactobacillus pseudoficulneus, and Vibrio alginolyticus, respectively, while the dominant fungal species was Apiotrichum laibachii. The predicted functional annotations revealed significant (p < 0.05) differences in the microbial pathways of the fermented and unfermented samples. The most abundant pathways in the MRI were the branched-chain amino acid biosynthesis super pathway and the pentose phosphate pathway. The CB sample was characterised by folate (vitamin B9) transformations III, and mixed acid fermentation. Biotin (vitamin B7) biosynthesis I and l-valine biosynthesis characterised the OPB sample. These findings can assist in identifying potential starter cultures for the commercial production of umqombothi. Specifically, A. pseudoficulneus can be used for controlled fermentation during the production of umqombothi. Likewise, the use of A. laibachii can allow for better control over the fermentation kinetics such as carbohydrate conversion and end-product characteristics, especially esters and aroma compounds.

This study compares, for the first time, the diversity and community structure of the endophytic archaea and fungi inhabiting the roots of maize plant cultivated using two different fertilizer regimes and the control field via shotgun metagenomics. This was used to verify our hypothesis that organic farming positively influences the diversity, beneficial effects, and abundance of plant endophytic communities as compared with conventional farming. Total DNA extraction was carried out using the roots of maize plants cultivated with organic fertilizer (FK), inorganic fertilizer (NK), and without any fertilizer (CK) at different farming sites in an experimental field and sequenced using shotgun metagenomics. In all, 3 archaea phyla, namely, Crenarchaeota, Euryarchaeota, and Thaumarchaeota, and 2 fungi phyla, namely, Ascomycota and Basidiomycota, were identified in the samples with higher abundance in samples from the FK site. Our diversity results revealed that the abundance of endophytic archaea and fungi species across the farming sites are in the order NK < CK < FK. The results indicate that organic farming enhances the abundance of endophytic archaea and fungi which might be a boost to sustainable agricultural practices. Furthermore, some new genera of endophytic archaea and fungi were identified from the maize roots. Future studies into how these novel endophytes can be cultured are important in a bid to explore their functions in sustainable agriculture as well as identify their biotechnological importance.

Rotational strip intercropping (RSI) of cereals and legumes has been developed and widely carried out to alleviate continuous cropping obstacles, to control erosion and to improve field use efficiency. In this study, a four-year fixed-field experiment was carried out in northeast China with three treatments: continuous cropping of maize, continuous cropping of peanuts and rotational strip intercropping of maize and peanut. The results show that crop rotation improved the main-stem height, branch number, lateral branch length, and yield and quality of peanuts; the yield was the highest in 2018, when it was increased by 39.5%. RSI improved the contents of total N, available N, total P, available P, total K and available K; the content of available N was the highest in 2018, with an increase of 70%. Rhizosphere soil urease and catalase activities were significantly increased and were the highest in 2017, reaching 183.13% and 91.21%, respectively. According to a high-throughput sequencing analysis, the rhizosphere soil bacterial richness and specific OTUs decreased in peanut rhizosphere soil, while the fungal increased. There were differences in the bacterial and fungal community structures; specifically, the abundance of Acidobacteria and Planctomycetes increased among bacteria and the abundance of beneficial microorganisms such as Ascomycota increased among fungi. In conclusion, rotational strip intercropping of maize and peanut increased the yield and quality of peanuts and conducive to alleviating the obstacles facing the continuous cropping of peanuts. Among then, soil physicochemical properties, enzyme activity and microbial diversity were significantly affected the yield of peanut.
