Phospholipid Fatty Acid Profiles of Bacteria and Fungi in Peat Exposed to Experimentally Increased N Deposition, 2015
Development of the oil sands has led to increasing atmospheric N deposition, with values as high as 17 kg N ha-1 yr-1; regional background levels <2 kg N ha-1 yr-1. Bogs, being ombrotrophic, may be especially susceptible to increasing N deposition. To examine responses to N deposition, over five years, we experimentally applied N (as NH4NO3) to a bog near Mariana Lakes, Alberta, at rates of 0, 5, 10, 15, 20, and 25 kg N ha-1 yr-1, plus controls (no water or N addition). In July of 2015 we measured PLFA markers in two depths in each plot. For the most part, microbial group abundances were not affected by increasing N input (Fig. 16). However, actinomycete abundance decreased with increasing N deposition at rates that were similar in 0-5 and 5-10 cm peat. Gram-negative bacteria increased slightly with increasing N input and were more abundant in 0-5 cm than in 5-10 cm peat; correspondingly the Gram-positive to Gram-negative bacterial ratio decreased with increasing N input and was lower in 0-5 cm than in 5-10 cm peat. Total microbial abundance and total bacterial abundance were significantly higher in 0-5 cm peat than in 5-10 cm peat. It may be that more sensitive/targeted techniques, such as high-throughput pyrosequencing, 16s RNA clone library analysis and rRNA-targeted fluorescence in situ hybridization (FISH) or whole genome shotgun sequencing may be required to reveal bog microbial community responses to N loading.
Phospholipid Fatty Acid Profiles of Bacteria and Fungi in Poor Fen Peat Exposed to Experimentally Increased N Deposition, 2015
Development of the oil sands has led to increasing atmospheric N deposition, with values as high as 17 kg N ha-1 yr-1; regional background levels <2 kg N ha-1 yr-1. To examine responses to N deposition, over five years, we experimentally applied N (as NH4NO3) to a poor fen near Mariana Lake, Alberta, at rates of 0, 5, 10, 15, 20, and 25 kg N ha-1 yr-1, plus controls (no water or N addition). In July of 2015 we measured PLFA markers in two depths in each plot. Fungal abundance increased at N addition levels above 16.6 kg N ha-1 yr-1 and total bacterial abundance also increased at N addition levels above 17.1 kg N ha-1 yr-1, such that the fungal:bacterial ratio was not significantly affected by N addition. Total microbial, gram-negative bacterial, and actinomycete abundance also showed an apparent threshold responses to N addition at 16-17 kg N ha-1 yr-1 addition levels.It may be that more sensitive/targeted techniques, such as high-throughput pyrosequencing, 16s RNA clone library analysis and rRNA-targeted fluorescence in situ hybridization (FISH) or whole genome shotgun sequencing may be required to reveal detailed fen microbial community responses to N loading.
Phospholipid fatty acids (PFLA) on decomposed litter: An evolutionary perspective on functional diversity in co-occuring willow(salix) species
Thirteen willow (Salix) species occur in southeastern Minnesota and often co-occur within the same wetlands. This high local diversity is challenging to explain since closely related species are often functionally similar and density-dependent interactions such as competition and susceptibility to pests and pathogens should limit their co-occurrence. However, if willow species are partitioning resources, or if they are phylogenetically structured so that closely related species rarely co-occur, then the impact of these density-dependent processes could be reduced. In this study, I examined the role of niche partitioning in maintaining local willow diversity by comparing species physiology in a greenhouse.

Data from: Microbial composition play the leading role in volatile fatty acid production in the fermentation of different scale of corn stover with rumen fluid
<p>Rumen fluid is a natural and green biocatalyst that can efficiently degrade biomass into volatile fatty acid (VFA) used to produce value-added materials. But the essence of high degradation efficiency in the rumen has not been fully analyzed. This study investigated the contribution of substrate structure and microbial composition to volatile fatty acid production in the fermentation of corn stover. The ball milled corn stover were innovatively applied to ferment with the rumen fluid collected at different digestion times. Exogeneous cellulase was also added to the ruminal fermentation to further reveal the inner mechanism. With prolonged digestion time, the microbial community relative abundance levels of Bacteroidetes and Firmicutes increased from 29.98% to 72.74% and decreased from 51.76% to 22.11%, respectively. The highest VFA production of the corn stover was achieved via treatment with the rumen fluid collected at 24 h which was up to 9508 mg/L. The ball milled corn stover achieved high VFA production because of the more accessible substrate structure. The application of exogenous cellulase has no significant influence to the ruminal fermentation. The microbial community abundance contributed more to the VFA production compared with the substrate structures.</p>

Data From: Fit and fatty freshwater fish: Contrasting polyunsaturated fatty acid phenotypes between hybridizing stickleback lineages
<p>Long-chain polyunsaturated fatty acids are biologically important lipids that are unevenly distributed between and throughout environments. This heterogeneity can affect the evolution of metabolic processes, as populations adapt to the resource landscape that they encounter. Here, we compare fatty acid phenotypes of stickleback over two time scales of evolutionary divergence: between two lineages with different metabolic capacities for fatty acid synthesis (i.e. different copy number of the fatty acid desaturase gene; FADS2) that independently colonized European freshwaters during the Pleistocene and Holocene; and between two ecotypes within each lineage that have diverged more recently (~150 years) in different habitats (i.e. lake and stream). We measured fatty acid profiles of wild-caught and lab-reared fish for each lineage and ecotype combination after rearing lab fish on a diet deficient in omega-3 long-chain polyunsaturated fatty acids. Since these lineages hybridize in nature, we also measured profiles of lab-reared hybrids and backcrosses raised on the same deficient diet. Wild fish showed strong compositional differences in fatty acids between habitats, lineages, and sexes. Common garden fish had generally lower polyunsaturated fatty acid levels than wild fish, and females had lower omega-6:omega-3 than males. Fish from the lineage with fewer FADS2 copies also had lower levels of docosahexaenoic acid. Overall, we document divergence in fatty acid phenotypes between stickleback lineages with different histories of freshwater colonization, and between ecotypes in the early stages of adaptive population divergence.</p>

Statin therapy inhibits fatty acid synthase via dynamic protein modifications
<p>Statins are a class of drugs widely prescribed to prevent cardiovascular disease, with pleiotropic cellular effects. Statins inhibit HMG-CoA reductase (HMGCR), which converts the metabolite HMG-CoA into mevalonate. Recent discoveries revealed HMG-CoA is a reactive metabolite that can non-enzymatically modify proteins and impact their activity. Therefore, we predicted that inhibition of HMGCR by statins might increase HMG-CoA levels and protein modifications. We observed a substantial increase in HMG-CoA levels upon statin treatment, and only a single protein was modified. Mass spectrometry revealed fatty acid synthase (FAS) was modified on active site residues, and surprisingly, the modification is located on non-lysine side-chains. The dynamic modifications occur only on a sub-pool of FAS near HMGCR and alter cellular signaling around the ER and Golgi. These results uncover communication between cholesterol and lipid biosynthesis by the substrate of one pathway inhibiting another in a rapid and reversible manner. </p>
Seasonal weight loss effect in the hepatic fatty acid composition in Australian Merino, Damara and Dorper sheep
<p>Seasonal weight loss (SWL) is one of the major limitations in small ruminant production in drought-prone regions. The study of breeds with higher tolerance to the effects of SWL is particularly important to define breed selection strategies. In this work we evaluated the effect of SWL in the hepatic fatty acids profile in three ovine breeds with different levels of tolerance: the Merino (susceptible to SWL), the Dorper (intermediate tolerant to SWL), and Damara (tolerant to SWL). </p>
