“…Climatic conditions in Mississippi are warm and temperate with short mild winters and hot humid summers (Potter & Xu, 2022). It is established that canola can grow at temperatures ranging from 12 to 30°C and this could fit in Mississippi production systems (Sey et al., 2020) as a winter annual crop. However, persistent high‐temperature conditions in Mississippi (>38°C) during April–July might affect the yield of canola.…”

The production of canola (Brassica napus L.) in the United States is low, whereas the demand is high. Most US canola research is centered in the Midwest, with minimal to no research in Southern states including Mississippi. Therefore, a study was conducted in Mississippi to assess the feasibility of canola as a double crop with soybean (Glycine max L.) rotation and determine its optimum nitrogen (N) requirement. After canola was harvested, soybean was planted within the same experimental plots. In total, six N treatments (0 [control], 34, 67, 101, 135, and 168 kg N ha−1) were applied to canola and replicated four times across all site‐years in a randomized complete block design. The application of N increased seed yield, aboveground biomass, and N content compared to the control in canola. Across all site‐years, the highest seed yield was 1726 kg ha−1 at 168 kg N ha−1. Moreover, N uptake, plant height, and test weight were highest at 135 kg N ha−1, which were 76%, 21%, and 44% greater than control, respectively. Oil content and seed weight were inversely related to N rates indicating dilution with increased N. Overall, 141 kg N ha−1 was found to be the agronomic optimum nitrogen rate, and no further supplementation was deemed necessary to maximize canola yield in Mississippi. Additionally, the following soybean crop benefitted from the N applied to canola and produced greater yields. This study establishes that canola has the potential for double cropping without adversely affecting subsequent soybean yield, provided optimum N rates are applied.

“…Olive oils are naturally protected by their high content of endogenous antioxidants (polyphenols and tocopherols); whereas some other oils (like sunflower, soybean, and peanut oils) must be enriched with exogenous antioxidants during their production due to the refining process they go through (Viana da Silva et al, 2021) to make them more oxidationresistant. Edible oils contain phytochemicals and phenolic compounds that have antiinflammatory, antioxidant, antibacterial, antiviral, antitumor, cardioprotective, antidiabetic, and anti-obesity activities, among other health advantages (Sumara et al, 2023, Xiao et al, 2022, Ali et al, 2022, Goyal et al, 2021, Sey et al, 2020, Chew 2020, Ghazani and Marangoni 2013, and Johnson et al, 2007.…”

In the present article, three samples (canola seed oil; CSO), (unfiltered olive oil; UFOO) and Canoliven (Canola seed oil: unfiltered olive oil, 80:20 w/w, respectively), were examined for phytochemical screening revealing the presence in all samples: steroids, terpenoids, saponins, tannins, anthocyanins alkaloids, phenols, and flavonoids. The results indicated that CSO variety Giza 56 contained 12 different chemical groups. Four physical characteristics were assayed in three samples. The acidity value ranged from 0.21 for CSO to 0.35 for UFOO and the acidity value for the canoliven is 0.25. Furthermore, the highest level of unsaponifiable matter % was found in CSO, followed by Canoliven and then UFOO. Peroxide value (meq O2/kg oil) ranged from 1.5 for CSO to 8.5 for UFOO, while Canoliven recorded 4.01. The highest level (6.5) of p-anisidine value (p-AV) was reported in the UFOO followed by CSO and Canoliven. Moreover, TOTOX values in Canoliven (11.2) and more than two folds of this value were recorded in UFOO (23.5). Additionally, the concentrations of saturated fatty acids (SFA%) in individual pure oils ranged from 16.29% for UFOO to 17.16% for CSO, while Canoliven recorded 17.01%. Total monounsaturated fatty acids (∑MUFA%) varied from 69.76 to 72.09% for UFOO, and CSO, respectively. The blending process improved the level of MUFA%, whereas its concentration in Canoliven reached 71.56%. The concentrations of polyunsaturated fatty acids (∑PUFA%) are 13.42, 10.57, and 11.43% in UFOO, CSO and Canoliven, respectively. Finally, some specialized analyses were conducted on the samples, including MDA, TPCs, OSI, and FTIR.

“…While the determination of the FA profile by gas chromatography combined with mass spectrometry (GCMS) is commonly used to assess cell membrane composition [20,21], headgroup profile investigation has often been neglected, possibly missing out valuable information. The identification of lipid headgroups is usually performed by thin-layer chromatography [22][23][24][25][26], but solution 31 P NMR can be used to identify and quantify cell membrane phospholipids, although it has rarely been applied to bacterial samples [27][28][29][30][31][32][33][34][35][36][37].…”

Cell labeling is a preliminary step in multiple biophysical approaches, including the solid-state nuclear magnetic resonance (NMR) study of bacteria in vivo. Deuterium solid-state NMR has been used in the past years to probe bacterial membranes and their interactions with antimicrobial peptides, following a standard labeling protocol. Recent results from our laboratory on a slow-growing bacterium has shown the need to optimize this protocol, especially the bacterial growth time before harvest and the concentration of exogenous labeled fatty acids to be used for both Escherichia coli and Bacillus subtilis. It is also essential for the protocol to remain harmless to cells while providing optimal labeling.We have therefore developed a fast and facile approach to monitor the lipid composition of bacterial membranes under various growth conditions, combining solution 31 P NMR and GCMS. Using this approach, the optimized labeling conditions of Escherichia coli and Bacillus subtilis with deuterated palmitic acid were determined. Our results show a modification of B. subtilis phospholipid profile as a function of the growth stage, as opposed to E. coli. Our protocol recommends low concentrations of exogenous palmitic acid in the growth medium, and bacteria harvest after the exponential phase.
