Changes in bacterial community structure and humic acid composition in response to enhanced extracellular electron transfer process in coastal sediment.

Arch Microbiol 2019 Apr 16. Epub 2019 Apr 16.

Key Laboratory of Biofuels, Shandong Provincial Key Laboratory of Energy Genetics, Qingdao Institute of Bioenergy and Bioprocess Technology, Chinese Academy of Sciences, Qingdao, 266101, China.

Humic acids are one of the main organic matters in sediments and contribute importantly to the marine biogeochemical cycles. Extracellular electron transfer is a ubiquitous natural process and has potentials to change the macrostructure of humic acids which can act as an electron shuttle. By setting up marine sediment microbial fuel cells, the present study revealed that enhanced extracellular electron transfer process could increase the content of C and H, but decrease the O content in humic acids, which could result in an increased aromaticity and decreased polarity of humic acids, whereas no significant changes occurred to the humification degree of the humic acids.

ACC deaminase plays a major role in Pseudomonas fluorescens YsS6 ability to promote the nodulation of Alpha- and Betaproteobacteria rhizobial strains.

Arch Microbiol 2019 Mar 15. Epub 2019 Mar 15.

Laboratório de Bioprocessos, Departamento de Microbiologia, Universidade Federal de Santa Catarina, Florianópolis, SC, Brazil.

Ethylene acts as a major regulator of the nodulation process of leguminous plants. Several rhizobial strains possess the ability to modulate plant ethylene levels through the expression of the enzyme 1-aminocyclopropane-1-carboxylate (ACC) deaminase; however, rhizobia present low enzymatic activities. One possible alternative to this problem resides on the use of free-living bacteria, such as Pseudomonas, presenting high levels of ACC deaminase activity that may be used as adjuvants in the nodulation process by decreasing inhibitory ethylene levels.

Department of Zoology, University of Delhi, Delhi, India.

Metagenomic surveys across microbial mat (~ 55 °C) samples of high-altitude (1760 m above sea level) Himalayan geothermal springs have revealed specialized community enriched with niche-specific functions. In this study, we have performed metagenomic sequence-based analyses to get insights into taxonomic composition and functional potential of hyperthermophiles in water (~ 95 °C) and sediment samples (78-98 °C). Community analyses revealed predominance of thermophilic bacterial and archeal genera dwelling in water in contrast to microbial mats (55 °C), namely Methylophilus, Methyloversatilis, Emticicia, Caulobacter, Thermus, Enhydrobacter and Pyrobaculum.

Department of Animal Sciences and Veterinary Medicine, Shanxi Agricultural University, Taigu, 030801, Shanxi, China.

Intestinal microbiota has been widely recognized to influence on their hosts with respect to digestion and absorption of nutrients, but little is known about the structure and composition of microbial communities at different growth periods of hosts as yet. In this case, 16S rRNA gene amplicon sequencing was applied to decode the microbiota architecture in four distinct intestinal compartments (duodenum, jejunum, ileum, and cecum) of both Large White pigs and Chinese Shanxi Black pigs at the weaning, nursery, and fast-growth developmental stages. In our study, the intestinal ecosystems were dynamically changing and influenced by host maturity and diets at different development stages. Read More
