Comparative study of eco- and cytotoxicity during biotransformation of anthraquinone dye Alizarin Blue Black B in optimized cultures of microscopic f…

2017

The aim of this study was to select optimal conditions (C and N sources, initial pH and temperature) for biodecolorization of 0.03% anthraquinone dye Alizarin Blue Black B (ABBB) by microscopic fungi: Haematonectria haematococca BwIII43, K37 and Trichoderma harzianum BsIII33. The phenolic compounds, phytotoxicity (Lepidium sativum L.), biotoxicity (Microtox), cytotoxicity and yeast viability assay were performed to determine the extent of ABBB detoxification. Biodecolorization and detoxification of 0.03% ABBB in H. haematococca BwIII43 and T. harzianum BsIII33 cultures was correlated with extracellular oxidoreductases activity. In turn, secondary products, toxic to human fibroblasts and res…

Cytotoxic effects of two extracts from garlic (Allium sativum L.) cultivars on the human squamous carcinoma cell line SCC-15

2018

Garlic (Allium sativum L., Alliaceae) has acquired a reputation as a therapeutic agent and herbal remedy to prevent and treat several pathologies. The aim of the present study was to determine the effect of two Allium sativum L. cultivars, Harnaś and Morado, on reactive oxygen species (ROS) production, viability and apoptotic process in human squamous carcinoma cell line SCC-15. The experiments were conducted on SCC-15 cell line exposed to increasing concentrations of garlic extracts of 0.062, 0.125, 0.250, 0.500 and 1.000 mg/mL. After the experiments, ROS formation, caspase-3 activity and neutral red uptake were measured in the cells, and in a collected medium lactate dehydrogenase (LDH) r…

Characterisation of odour active compounds along extraction process from pea flour to pea protein extract

2013

International audience; Pisum sativum, rich in proteins, represents a main interest for human food. Nevertheless, pea products are underused because of their organoleptic characteristics. The extraction process of the proteins can partly explain the development of the typical flavour.The objective of the present study was to identify odour active compounds and to follow their evolution during four steps of the process (from pea flour to pea protein).Firstly, volatile compounds were extracted by Solvent Assisted Flavour Evaporation from each step and analysed by Gas Chromatography coupled with Mass Spectrometry and Olfactometry. Secondly, the volatile compounds, identified as odour active in…

Effetti della concimazione sulla qualità dell'aglio coltivato in Sicilia. Effects of fertilization on the quality of garlic grown in Sicily.

2010

In order to expand this crop and to improve bulbs quality a study was carried out to evaluate different fertilization techniques. Four fertilization formulas were evaluated: 1) mineral fertilization commonly used by Paceco producers - pre-planting with 55, 110 and 80 kg ha-1 of N, P2O5 and K2O - post planting with 47 and 46 kg ha-1 of N and K2O; 2) organic fertilization with an organic mix - pre-planting with 320 and 240 kg ha-1 of N and P2O5; 3) mineral fertilization - pre-planting with 40, 70 and 100 kg ha-1 of N, P2O5 and K2O - post-planting with 80 kg ha-1 of N half at 3-4 leaves and half at bulbs formation; 4) only post-planting fertilization with 52 and 184 kg ha-1 of N and K2O, half …

Cadmium accumulation and buffering of cadmium-induced stress by arbuscular mycorrhiza in three Pisum sativum L. genotypes

2002

The role of arbuscular mycorrhiza in reducing Cd stress was investigated in three genotypes of Pisum sativum L. (cv. Frisson, VIR4788, VIR7128), grown in soil/sand pot cultures in the presence and absence of 2-3 mg kg(-1) bioavailable Cd, and inoculated or not with the arbuscular mycorrhizal fungus Glomus intraradices. Shoot, root and pod biomass were decreased by Cd in non-mycorrhizal plants. The presence of mycorrhiza attenuated the negative effect of Cd so that shoot biomass and activity of photosystem II, based on chlorophyll a fluorescence, were not significantly different between mycorrhizal plants growing in the presence or absence of the heavy metal (HM). Total P concentrations were…

Chemical composition and phytotoxic effects of essential oils of Salvia hierosolymitana Boiss. and Salvia multicaulis Vahl. var. simplicifolia Boiss.…

2009

The chemical composition of the essential oils of S. hierosolymitana Boiss. and S. multicaulis Vahl. var. simplicifolia Boiss. collected in Lebanon was studied by means of GC and GC-MS analysis. In all 115 compounds were identified: 82 for S hierosolymitana and 72 for S. multicaulis var. simplicifolia. The presence of carbonylic compounds (17%) characterizes the oil from S. hierosolymitana, while S. multicaulis var. simplicifolia oil is rich of monoterpenes (34.5%) and sesquiterpenes (46.9%). The effects of the essential oils on germination and initial radical elongation of Raphanus sativus L. (radish) and Lepidium sativum L. (garden cress) were studied, indicating in a different activity a…

Taking into account soils and climate change in assessing the production potential of a legume crop of interest: pea

2022

In the current context of climate change and increasing pressure on resources, the agricultural production model isbeing questioned. The challenge of a more autonomous, efficient and sustainable production of proteins must bemet by increasing the use of legumes in French cropping systems. The pea (Pisum sativum L.) crop model “AzodynPea” will be used to identify zones and management techniques favorable to the crop in Burgundy-Franche-Comté(eastern France), taking into account abiotic stresses, such as winter frost or water deficit. The first step in this processis the mapping of current soil properties and current and future climate characteristics of the region. Regionalizeddaily climate …
