Mucin pre-cultivated Lactobacillus reuteri E shows enhanced adhesion and increases mucin expression in HT-29 cells.

Antonie Van Leeuwenhoek 2020 Aug 14;113(8):1191-1200. Epub 2020 May 14.

Department of Cell and Molecular Biology of Drugs, Faculty of Pharmacy, Comenius University in Bratislava, Odbojárov 10, Bratislava, Slovak Republic.

Adhesion of probiotic bacteria to the mucus layer lining the gastrointestinal tract is necessary for its effective colonisation and specific therapeutic effects. Enrichment of growth medium with mucin might stimulate bacterial adhesion, probably by increasing the expression of surface structures responsible for bacteria-gut epithelia and/or mucus interactions. The aim of this study was to determine if pre-cultivation of potentially probiotic strain Lactobacillus reuteri E (LRE) with mucin stimulates its adherence to colon cell line HT-29 and if the increased adhesion modulates mucin expression in these cells.

Symbiotic yeasts from the mycangium, larval gut and woody substrate of an African stag beetle Xiphodontus antilope (Coleoptera: Lucanidae).

Antonie Van Leeuwenhoek 2020 Aug 21;113(8):1123-1134. Epub 2020 Apr 21.

H. G. W. J. Schweickerdt Herbarium, Department of Plant and Soil Sciences, Plant Sciences Complex, University of Pretoria, Private Bag X20, Hatfield, 0028, South Africa.

Female stag beetles (Lucanidae) possess internal mycangia to maintain microbial cultures. Yeasts from these mycangia may help with larval nutrition in nutrient poor woody substrates, but only a few Lucanidae taxa have been studied and all reports originate from Europe and Asia. We identify the first mycangial yeasts of a South African endemic Lucanidae beetle, Xiphodontus antilope, using nuclear ribosomal RNA and ITS DNA sequence data. Read More

Screening bacterial phosphate solubilization with bulk-tricalcium phosphate and hydroxyapatite nanoparticles.

Antonie Van Leeuwenhoek 2020 Jul 21;113(7):1033-1047. Epub 2020 Apr 21.

Environmental Microbiology Laboratory, Colegio de Postgraduados, Campus Montecillo, km. 36.5 Carretera Mexico-Texcoco, 56230, Texcoco Estado de Mexico, Mexico, Mexico.

Phosphate-solubilizing bacteria can release phosphorus (P) from insoluble minerals and benefit either soil fitness or plant growth. Bulk sized P compounds have been suggested but little is known about solubilization of nanosized materials such as hydroxyapatite nanoparticles (HANP). A screening of the initial 43 strains from vanilla rhizospheres for phosphate solubilization with bulk Ca(PO) was carried out. Read More

Genomic sequencing of Gracilibacillus dipsosauri reveals key properties of a salt-tolerant α-amylase.

Antonie Van Leeuwenhoek 2020 Jul 21;113(7):1049-1059. Epub 2020 Apr 21.

Bioinformatics Core Facility, Knowledge Enterprise, Arizona State University, Tempe, AZ, 85281, USA.

Gracilibacillus dipsosauri is a moderately-halophilic Gram-positive bacterium which forms an extracellular α-amylase that is induced by starch, repressed by D-glucose, and active in 2.0 M KCl. Previous studies showed that while enzyme activity could be measured with the synthetic substrate 2-chloro-4-nitrophenyl-α-D-maltotrioside (CNPG3), other assays were inconsistent and the protein showed aberrant mobility during nondenaturing gel electrophoresis.

Anaplasmataceae closely related to Ehrlichia chaffeensis and Neorickettsia helminthoeca from birds in Central Europe, Hungary.

Antonie Van Leeuwenhoek 2020 Jul 21;113(7):1067-1073. Epub 2020 Apr 21.

Department of Parasitology and Zoology, University of Veterinary Medicine, Budapest, 1078, Hungary.

Increasing amount of data attest that (in the context of vector-borne infections) birds are not only important as hosts of blood-sucking arthropod vectors, but also as reservoirs of vector-borne pathogens. From 2015 to 2019 cadavers of 100 birds (from 45 species, nine orders) were collected in Hungary, and their organs were screened for DNA from a broad range of vector-borne bacteria with PCR and sequencing. Molecular analyses revealed the presence of Anaplasmataceae, and sequencing identified bacteria closely related to Neorickettsia helminthoeca and Ehrlichia chaffeensis in a Eurasian teal (Anas crecca) and a song thrush (Turdus philomelos), respectively.

Improving the yields of thurincin H in a native producer strain.

Antonie Van Leeuwenhoek 2020 Jul 20;113(7):1061-1066. Epub 2020 Apr 20.

Life Science Division, Graduate Program in Biosciences, University of Guanajuato Campus Irapuato-Salamanca, 36500, Irapuato, Guanajuato, Mexico.

Thurincin H is a bacteriocin produced by Bacillus thuringiensis with activity against a wide range of bacteria, including Gram positive and Gram negative. Disadvantages of producing thurincin H in B. thuringiensis is the low production level in the native strain probably due to the highly regulated mechanism of biosynthesis. Read More
