Bacterial colonisation of reeds and cottonseed hulls in the rumen of Tarim red deer (Cervus elaphus yarkandensis).

Antonie Van Leeuwenhoek 2019 Apr 2. Epub 2019 Apr 2.

Department of Special Animal Nutrition and Feed Science, Institute of Special Animal and Plant Sciences, Chinese Academy of Agricultural Sciences, 130112, Changchun, China.

The rumen microbiome contributes greatly to the degradation of plant fibres to volatile fatty acids and microbial products, affecting the health and productivity of ruminants. In this study, we investigated the dynamics of colonisation by bacterial communities attached to reeds and cottonseed hulls in the rumen of Tarim red deer, a native species distributed in the desert of the Tarim Basin. The reed and cottonseed hull samples incubated in nylon bags for 1, 6, 12, and 48 h were collected and used to examine the bacterial communities by next-generation sequencing of the bacterial 16S rRNA gene.

Antibiotic susceptibility of marine Planctomycetes.

Antonie Van Leeuwenhoek 2019 Mar 27. Epub 2019 Mar 27.

Departamento de Biologia, Faculdade de Ciências, Universidade do Porto, Rua do Campo Alegre s/n, 4169-007, Porto, Portugal.

Antimicrobials are naturally produced by microbes and therefore have always been present in their environment, as well as accompanying resistance mechanisms. The antibiotic resistance profile of environmental species is particularly relevant since genetic determinants of resistance can spread through horizontal gene transfer and reach clinically important species. The phylum Planctomycetes comprises Gram-negative bacteria characterised by unusual features and appear to be ubiquitously distributed. Read More

Sugarcane must fed-batch fermentation by Saccharomyces cerevisiae: impact of sterilized and non-sterilized sugarcane must.

Antonie Van Leeuwenhoek 2019 Mar 4. Epub 2019 Mar 4.

Department of Genetics, "Luiz de Queiroz" College of Agriculture, University of São Paulo, Av. Pádua Dias 11, Piracicaba, SP, 13400-970, Brazil.

The presence of microbial contaminants is common in the sugarcane ethanol industry and can decrease process yield, reduce yeast cell viability and induce yeast cell flocculation. To evaluate the effect of microbial contamination on the fermentation process, we compared the use of sterilized and non-sterilized sugarcane must in the performance of Saccharomyces cerevisiae with similar fermentation conditions to those used in Brazilian mills. Non-sterilized sugarcane must had values of 10 and 10 CFU mL of wild yeast and bacterial contamination, respectively; decreased total reducing sugar (TRS); and increased lactic and acetic acids, glycerol and ethanol concentrations during storage.

Phylogenomic analysis of the Brevibacillus brevis clade: a proposal for three new Brevibacillus species, Brevibacillus fortis sp. nov., Brevibacillus porteri sp. nov. and Brevibacillus schisleri sp. nov.

Antonie Van Leeuwenhoek 2019 Jan 29. Epub 2019 Jan 29.

Crop Bioprotection Research Unit, USDA ARS, 1815 N. University Street, Peoria, IL, 61604, USA.

During a screen for antifungal activity of Brevibacillus strains in the Northern Regional Research Laboratory collection we identified two strains with strong activity. Subsequent genomic sequencing and phylogenomic analysis revealed that these strains (NRRL NRS-1210 and NRRL B-41110) are likely novel species. To confirm their taxonomic placement, we conducted a 16S rRNA phylogenetic analysis and subsequently sequenced the genomes of 10 Brevibacillus type strains with a 16S homology > 97%. Read More

Production of a novel killer toxin from Saccharomyces eubayanus using agro-industrial waste and its application against wine spoilage yeasts.

Antonie Van Leeuwenhoek 2019 Jan 22. Epub 2019 Jan 22.

Instituto de Investigación y Desarrollo en Ingeniería de Procesos, Biotecnología y Energías Alternativas (PROBIEN, Consejo Nacional de Investigaciones Científicas y Tecnológicas - Universidad Nacional del Comahue), Buenos Aires 1400, 8300, Neuquén, Argentina.

The juicing industry generates large amounts of waste that mostly lack commercial value and, in the absence of waste treatment policies, produces environmental pollution. Also, microbiological spoilage is a major concern in the wine industry and control tools are limited. Taking these challenges into account, agro-industrial waste coming from ultrafiltrated apple and pear juice were used to grow Saccharomyces eubayanus and to produce its killer toxin (SeKT).

Selection of thermotolerant Saccharomyces cerevisiae for high temperature ethanol production from molasses and increasing ethanol production by strain improvement.

Antonie Van Leeuwenhoek 2019 Jan 21. Epub 2019 Jan 21.

Department of Microbiology, Faculty of Science, Kasetsart University, Chatuchak, Bangkok, 10900, Thailand.

A thermotolerant ethanol fermenting yeast strain is a key requirement for effective ethanol production at high temperature. This work aimed to select a thermotolerant yeast producing a high ethanol concentration from molasses and increasing its ethanol production by mutagenesis. Saccharomyces cerevisiae DMKU 3-S087 was selected from 168 ethanol producing strains because it produced the highest ethanol concentration from molasses at 40 °C. Read More

Culturomics has recently allowed the isolation and description of previously uncultured bacteria from the human microbiome at different body sites. As part of a project aiming to describe the human gut microbiota by culturomics, Phoenicibacter congonensis strain Marseille-P3241 was isolated from the gut of a 45 years old Pygmy female. In the present work, we aim to describe this strain via the taxonogenomics approach. Read More
