Project description:To investigate the effects of organic fertilizer replacing chemical fertilizer on the growth and development of barley (Kunlun-14), a pot experiment was conducted. The study examined the impacts of different ratios of organic fertilizer replacing chemical fertilizer nitrogen (0%, 40%, 100%, denoted as OFR0, OFR40, OFR100, respectively) on the growth characteristics, leaf carbon-nitrogen balance, and nitrogen metabolism enzyme activities of barley.

Project description:Anaerobic digestion is a popular and effective microbial process for waste treatment. The performance of anaerobic digestion processes is contingent on the balance of the microbial food web in utilizing various substrates. Recently, co-digestion, i.e., supplementing the primary substrate with an organic-rich co-substrate has been exploited to improve waste treatment efficiency. Yet the potential effects of elevated organic loading on microbial functional gene community remains elusive. In this study, functional gene array (GeoChip 5.0) was used to assess the response of microbial community to the addition of poultry waste in anaerobic digesters treating dairy manure. Consistent with 16S rRNA gene sequences data, GeoChip data showed that microbial community compositions were significantly shifted in favor of copiotrophic populations by co-digestion, as taxa with higher rRNA gene copy number such as Bacilli were enriched. The acetoclastic methanogen Methanosarcina was also enriched, while Methanosaeta was unaltered but more abundant than Methanosarcina throughout the study period. The microbial functional diversity involved in anaerobic digestion were also increased under co-digestion.

Project description:Background and aims The endophytic diazotrophic strain CBAmC of Nitrospirillum amazonense has been reported as a plant growth promoter of sugarcane variety RB867515 when grown under field conditions. The present work aimed to assess the influence of apoplast fluid from RB867515 on the transcriptomic and proteomic profiles of CBAmC cultured in vitro. Methods RNA-Seq in Ion Proton™ and ESI-LC-MS/MS peptide analysis were used to evaluate the transcriptomic and proteomic profiles, respectively, of CBAmC exposed for 2 h to the sugarcane apoplast fluid. Results The bacterial transcriptomic and proteomic profiles were well correlated. The overall response of CBAmC to the apoplast fluid included overexpression of defense systems against reactive oxygen species (ROS) and osmotic stress, RND efflux pumps for toxic compounds, Sec and Tat secretory systems, and assimilative metabolism of iron. In contrast, active transporters of organic compounds, chemotaxis system and flagellum structure were underexpressed. Conclusions The bacterial metabolic pathways / functions activated in response to the sugarcane apoplast fluid are most likely related to its adaptation to the peculiar characteristics of the fluid. The activation of some of those functions could be determinant for its adaptation to the sugarcane apoplastic niche, and perhaps be involved in the previously observed effect of promoting plant growth.

Project description:Aquatic microorganisms are typically identified as either oligotrophic or copiotrophic, representing trophic strategies adapted to low or high nutrient concentrations, respectively. Here, we sought to take steps towards identifying these and additional adaptations to nutrient availability with a quantitative analysis of microbial resource use in mixed communities. We incubated an estuarine microbial community with stable isotope labeled amino acids (AAs) at concentrations spanning three orders of magnitude, followed by taxon-specific quantitation of isotopic incorporation using NanoSIMS analysis of high-density microarrays. The resulting data revealed that trophic response to AA availability falls along a continuum between copiotrophy and oligotrophy, and high and low activity. To illustrate strategies along this continuum more simply, we statistically categorized microbial taxa among three trophic types, based on their incorporation responses to increasing resource concentration. The data indicated that taxa with copiotrophic-like resource use were not necessarily the most active, and taxa with oligotrophic-like resource use were not always the least active. Two of the trophic strategies were not randomly distributed throughout a 16S rDNA phylogeny, suggesting they are under selective pressure in this ecosystem and that a link exists between evolutionary relatedness and substrate affinity. The diversity of strategies to adapt to differences in resource availability highlights the need to expand our understanding of microbial interactions with organic matter in order to better predict microbial responses to a changing environment. manuscript accepted by PLoS ONE 4 datasets: 1) fluorescence data for 3 treatments combined, 2) isotopic data for treatment = LOW, 3) isotopic data for treatment = MEDIUM, 4) isotopic data for treatment = HIGH
