Are Key Acetate Assimilators During Complete Denitrification in Acidic Cryoturbated Peat Circles of the Arctic Tundra.

Front Microbiol 2021 5;12:628269. Epub 2021 Feb 5.

Institute of Microbiology, Leibniz University Hannover, Hannover, Germany.

Cryoturbated peat circles (pH 4) in the Eastern European Tundra harbor up to 2 mM pore water nitrate and emit the greenhouse gas NO like heavily fertilized agricultural soils in temperate regions. The main process yielding NO under oxygen limited conditions is denitrification, which is the sequential reduction of nitrate/nitrite to NO and/or N. NO reduction to N is impaired by pH < 6 in classical model denitrifiers and many environments. Read More

Characterization of Thiomonas delicata arsenite oxidase expressed in Escherichia coli.

3 Biotech 2017 Jun 30;7(2):97. Epub 2017 May 30.

Department of Biosciences and Health Sciences, Faculty of Biosciences and Medical Engineering, Universiti Teknologi Malaysia, 81310, Skudai, Johor, Malaysia.

Microbial arsenite oxidation is an essential biogeochemical process whereby more toxic arsenite is oxidized to the less toxic arsenate. Thiomonas strains represent an important arsenite oxidizer found ubiquitous in acid mine drainage. In the present study, the arsenite oxidase gene (aioBA) was cloned from Thiomonas delicata DSM 16361, expressed heterologously in E. Read More

Phylogenetic composition and properties of bacteria coexisting with the fungus Hypholoma fasciculare in decaying wood.

ISME J 2009 Oct 11;3(10):1218-21. Epub 2009 Jun 11.

Laboratory of Environmental Microbiology, Institute of Microbiology of the ASCR, v.v.i., Prague 4 14220, Czech Republic.

White-rot fungi are major degraders of woody materials in terrestrial environments because of their ability to decompose lignin. However, little is known on the possible associations of white-rot fungi with other microorganisms during wood decay. We investigated the numbers, community composition and functional traits of bacteria present in natural wood samples under advanced decay by the white-rot basidiomycete Hypholoma fasciculare.

Characterization of a photosynthetic Euglena strain isolated from an acidic hot mud pool of a volcanic area of Costa Rica.

FEMS Microbiol Ecol 2002 Oct;42(1):151-61

Centro de Investigación en Biología Celular y Molecular (CIBCM), Universidad de Costa Rica, Ciudad Universitaria Rodrigo Facio, San José, Costa Rica.

Abstract Conspicuous green patches on the surface of an acidic hot mud pool located near the Rincón de la Vieja volcano (northwestern Costa Rica) consisted of apparently unialgal populations of a chloroplast-bearing euglenoid. Morphological and physiological studies showed that it is a non-flagellated photosynthetic Euglena strain able to grow in defined mineral media at temperatures up to 40 degrees C and exhibiting higher thermotolerance than Euglena gracilis SAG 5/15 in photosynthetic activity analyses. Molecular phylogeny studies using 18S rDNA and GapC genes indicated that this strain is closely related to Euglena mutabilis, another acid-tolerant photosynthetic euglenoid, forming a clade deeply rooted in the Euglenales lineage.

Clostridium akagii sp. nov. and Clostridium acidisoli sp. nov.: acid-tolerant, N2-fixing clostridia isolated from acidic forest soil and litter.

Int J Syst Evol Microbiol 2000 Mar;50 Pt 2:873-881

Two anaerobic acid-tolerant bacteria, CK58T and CK74T, were isolated from acidic beech litter and acidic peat-bog soil, respectively. Both bacteria were spore-forming, motile rods with peritrichous flagella. The capacity to sporulate decreased with prolonged cultivation. Read More

Biodiversity of lactic acid bacteria from food-related ecosystems.

Microbios 1995 ;83(334):13-22

Department of Microbiology, University of the Witwatersrand, Johannesburg, South Africa.

The diversity of lactic acid bacteria within a variety of food-related ecosystems was assessed and the strain as well as environment specific characteristics were investigated. The strains (108 in toto) were isolated from plant material, traditional fermented foods, dried marine algae, sea food, fungi as well as spoiled foods and beverages, and all were characterized to genus level. Lactobacillus strains dominated all ecosystems and contributed to 65% of the isolates while a further 13% consisted of Lactococcus strains, 12% of Leuconostoc strains, 5% of Pediococcus strains, and 5% of unidentified strains.

Hydrophobic Membrane Filtration Method for the Selective Recovery and Differentiation of Zygosaccharomyces bailii in Acidified Ingredients.

John P Erickson

J Food Prot 1993 Mar;56(3):234-238

Best Foods Research and Engineering Center, CPC International, Inc., P.O. Box 1534, 1120 Commerce Avenue, Union, New Jersey 07083-5088.

A single-step enumeration and identification pour plate medium was developed for Zygosaccharomyces bailii that totally inhibited environmental nonspoilage yeast and mold growth and supported high (93.9-97%) Z. bailii recovery rates. Read More
