Quan, Wenxuan published the artcileDynamics of volatile organic compounds in Masson pine (Pynus massonyana Lamb.) seedling needles under drought stress, Recommanded Product: Methyl decanoate, the main research area is Pinus drought stress volatile organic compound seedling.

The aim of this study is to evaluate whether volatile organic compounds (VOCs) of Masson pine adapted their physiol. responses under drought stress or not. The needle length, root length, root/shoot ratio and the VOCs of Masson pine seedlings under drought stress were investigated by comprehensive two-dimensional gas chromatog. time of flight mass spectrometry (GCxGC-TOFMS). The results showed that the growth index was enhanced with the increase of stress strength, and the seedling growth, biomass, needle length, and root length were inhibited compared with the well-watered treatment. The amounts of total VOCs under drought stress were increased, the concentration of terpenoids, acids and esters, under drought stress were higher than the well-watered treatment, but the concentration of alcs. and carbonyl compounds was slightly decreased under the moderate drought treatment. Light drought, moderate drought, and severe drought compared with the well-watered treatment, increased the release of VOCs by 49, 50, and 49%, resp. The results show a key role of the VOCs released in the needles and therefore play a possible key role in drought resistance. This study provides evidence that the needles of Masson pine release more VOCs to adapt to drought conditions.

Radhakrishnan, Rokesh published the artcileSustainable approach for the treatment of poultry manure and starchy wastewater by integrating dark fermentation and microalgal cultivation, Quality Control of 110-42-9, the main research area is poultry manure starchy wastewater dark fermentation microalgal cultivation.

Dwindling fossil fuels, and the rise in energy demand have urged us to explore alternative renewable energy forms. An integrated process of dark fermentation and microalgal cultivation to deliver biofuels are gaining momentum in recent times. In this study, in the first stage, the starchy wastewater (SWW) with poultry manure (PM) was treated to produce a maximum hydrogen yield of 4.11 mol H2/Kg COD reduced to 5.03 mol H2/Kg COD reduced. The reutilization of soluble spent wash for the cultivation of Chlamydomonas reinhardtii yielded a biomass concentration of 1.45-1.02 g/L. The potentiality of algae to produce biodiesel was checked effectively, and it was reported that a biodiesel of 90.34 g/Kg Algal Biomass to 119.61 g/Kg Algal was yielded. The integration of the process enhanced the overall energy with an efficient removal of organic content. In conclusion, the valorisation of PM with SWW through dark fermentation and microalgal cultivation will open avenues to generate sustainable bioenergy forms.

Anand, Manasa published the artcileIntegrated Biodiesel and Biogas Production from Chlamydomonas reinhardtii, Related Products of esters-buliding-blocks, the main research area is biodiesel biogas Chlamydomonas transesterification anaerobic digestion.

In this study, we focus on the production of energy efficient Biodiesel and Biomass, whose principle is to extract the maximum amount of energy from biomass, the biodiesel production i.e. the lipid extraction from the biomass through the transesterification process and the residue is then subjected for the anaerobic process for biogas (methane) production and the leftover residue can be used for various other purposes. From this study we observed that cultivation of microalgae in open pond system using fertilizer as nutrients will reduce the most of biomass production since construction of and use of open ponds is cheaper than using photobioreactors thereby reducing the fixed capital investment. Using fertilizers as nutrient source will decrease the working capital , thus reduction in overall process but major problems like salt precipitation, evaporation and change in pH due to external environment were observed in open pond; these can be overcome by taking extra care and optimization. Gas chromatog.-Mass spectroscopy (GC-MS) anal. of crude biodiesel sample confirmed the presence of fatty acid Me ester (biodiesel). The green circle in GC-MS anal. ndicates presence of decanoic acid Me ester. The maximum amount of biogas produced was 10 cm3 in 27 days. The maximum amount of biogas produced from the algal biomass was 12 cm3 for 18 – 27 days. The Gross calorific value was found to be 333 kcal/kg. The percentage of methane present was found to be 2.5% and the percentage of carbon dioxide present was found to be 2.59%.From the energy balance, the calorific value of the biogas produced from the residue after lipid extraction was found to be 0.81 kcal. From the feasibility study conducted, it was found that the cost of new media’s formulated using fertilizers is approx. ten times less than High Salt Media thereby reducing the overall cost which improves the economics of biodiesel production

Seventy-eight graviera cheese samples produced in five different regions of Greece were characterized and discriminated according to geog. origin. For the above purpose, pH, titratable acidity (TA), NaCl, proteins, fat on a dry weight basis, ash, fatty acid composition, volatile compounds, and minerals were determined Both multivariate anal. of variance (MANOVA) and linear discriminant anal. (LDA) were applied to exptl. data to achieve sample geog. discrimination. The results showed that the combination of fatty acid composition plus minerals provided a correct classification rate of 89.7%. The value for the combination of fatty acid compositions plus conventional quality parameters was 94.9% and for the combination of minerals plus conventional quality parameters was 97.4%. When cheeses of the above five geog. origins were combined with previously studied graviera cheeses from six other geog. origins collected during the same seasons in Greece, the resp. values for the discrimination of geog. origin of all eleven origins were 89.3% for conventional quality parameters plus minerals; 94.0% for conventional quality parameters plus fatty acids; 94.1% for minerals plus fatty acids; and 95.2% for conventional quality parameters plus minerals plus fatty acids. Such high correct classification rates demonstrate the robustness of the developed statistical model.

Zhao, Huiyan published the artcileIdentification of the influential odorants for the unpleasant rancid smell of ripe noni fruit (Morinda citrifolia), HPLC of Formula: 110-42-9, the main research area is Morinda fruit hexanoic octanoic acid methyl ester odorant.

In this study, the volatile changes of noni fruit in various ripening stages were analyzed using gas chromatog.-mass spectrometry. Eleven of the 35 identified volatiles were found odor-active through gas chromatog.-olfactometry. Based on the aroma extract dilution anal., hexanoic acid, octanoic acid and their Me esters were considered as the key odorants for the smell of noni fruit. Anal. also indicated that the sensory perception of the rancid smell was resulted from the antagonistic effects of the key acid and Me ester odorants. This study may facilitate the improvement of the acceptability of noni processed foods in the future.

Wu, Qiang-Sheng published the artcileMycorrhizas enhance drought tolerance of citrus by altering root fatty acid compositions and their saturation levels, Recommanded Product: Methyl decanoate, the main research area is mycorrhiza drought citrus root fatty acid saturation; Poncirus trifoliata ; drought; mycorrhizal symbiosis; unsaturation index of fatty acids.

Arbuscular mycorrhizas (AMs) have the ability to enhance drought tolerance of citrus, but the underlying mechanisms have not been clearly elucidated. Considering the strong association of cell membrane fatty acid (FA) unsaturation with plant drought tolerance, the present study hypothesized that AM fungi (AMF) modulated the composition and unsaturation of FAs to enhance drought tolerance of host plants. Drought-sensitive citrus rootstocks, trifoliate orange (Poncirus trifoliata) seedlings, were inoculated with AMF (Funneliformis mosseae) for 3 mo and were subsequently exposed to drought stress (DS) for 8 wk. Mycorrhizal seedlings exhibited better plant growth performance, higher leaf water potential and lower root abscisic acid concentrations under both well-watered (WW) and DS conditions. Arbuscular mycorrhiza fungus inoculation considerably increased root Me oleate (C18:1), Me linoleate (C18:2) and Me linolenate (C18:3N3) concentrations under both WW and DS conditions, and root Me palmitoleate (C16:1) concentrations under WW, while it decreased root Me stearate (C18:0) levels under both WW and DS. These changes in the composition of FAs of mycorrhized roots resulted in higher unsaturation index of root FAs, which later aided in reducing the oxidative damage on account of lower concentration of malondialdehyde and superoxide radicals. The changes of these FAs were a result of AMF-up-regulating root FA desaturase 2 (PtFAD2), FA desaturase 6 (PtFAD6) and Δ9 FA desaturase (PtΔ9) genes under WW and PtFAD2, PtFAD6 and Δ15 FA desaturase (PtΔ15) genes under DS conditions. Our results confirmed that mycorrhization brought significant changes in root FA compositions, in addition to regulation of gene expression responsible for increasing the unsaturation level of FAs, a predisposing physiol. event for better drought tolerance of citrus.
