“…In fact, the progressive reductions in the PLA, STA and PUFA contents in general correlated with a significant increase in the MGA and OLA contents of the oils obtained from the corn kernels stored in the control batch and the simple triple bagging at the end of storage could be due to interactionand the exchange of fatty acids carried out by microorganisms 27,28 . Similar observations were made by Al-Abdalall and AL-Juraifani 29 , then Yin et al 30 and De Carvalho et al 31 during the respective storage of coffee beans, corn and sunflower seed. Also, Ortega et al 32 recorded losses of 70-90% PLA, 65-90% STA during storage of wheat grains.…”

“…For these different authors, microorganisms, through their metabolism, produce lipolytic enzymes which allow them to break down the fat in grains in order to use fatty acids for their growth 33 . N'kouam 34 , Al-abdalall and Al-Juraifani 29 and De Carvalho et al 31 also mentioned the effect of storage on fat composition during the respective storage of aiele fruit, coffee seeds and sunflower seeds. Moreover, Tamendjari et al 35 then Ortega et al 32 , in their study on bacterial and fungal infestations during storage of olive seeds and wheat grains, under conditions of relative humidity between 50 and 100%, would have indeed shown that the actual presence of these microorganisms negatively affected the PUFA content of the extracted oils.…”

Corn oil is considered one of the best edible vegetable oils. Unfortunately, the storage of corn kernels as practiced in rural areas affects the quality of the fat. However, the triple bagging system and aromatic plants remain alternatives to the poor storage practiced by certain players in the ivorian maize sector. However, their influence on the quality of the fat in the grains remains to be elucidated. This study aims to evaluate, during storage, the fatty acid (FA) profile of the oil obtained from corn kernels packaged in a triple bagging system with or without the leaves of Lippia multiflora and Hyptis suaveolens. Thus, 6 batches including one control in polypropylene bag, one batch in triple bagging without biopesticides and four batches in triple bagging with variable proportions and/or combination of Lippia multiflora and Hyptis suaveolens (2.5 % and 5 % and a combination 0 to 100 % Lippia) were made up to follow the evolution of the fatty acid (FA) composition of the extracted oils during six observation periods (0 ; 1 ; 4.5 ; 9.5 ; 14.5 and 18 months). The estimated intake and fatty acid contribution were also evaluated after 18 months of storage. The storage time and the type of packaging have a significant influence on the fatty acid profile of oils. During grain storage, the FA profile of the oils obtained from the grains stored in the triple bagging with the biopesticides varied very little. At the end of storage, their average composition was 13.40 % saturated fatty acids (SFA), 31.76 % monounsaturated fatty acids (MUFA) and 50.45 % polyunsaturated fatty acids (PUFA). On the other hand, at the end of grain storage, the grain oil from the triple bagged batch without biopesticides consists of 16 % SFA, 38.85 % MUFA, and 45.70 % PUFA. The contribution to meeting energy needs is ensured from the consumption of oil from grains stored for 18 months in triple bagging systems associated with biopesticides. Therefore the combination of these aromatic leaves with triple bagging is more advantageous to preserve the FA profile of the grains during storage.

“…There is a continuing interest in modifying the biochemical composition of fungal species by influencing abiotic or environmental factors. It is well studied that the chemical composition of microorganisms is affected by varied environmental conditions ( 48 ). Temperature plays a vital role in growth and lipid accumulation and can alter the composition of cellular fatty acids ( 34 ).…”

In this study, 18 standard amino acids were tested as a single nitrogen source on biomass, total lipid, total fatty acid (TFA) production, and yield of γ-linolenic acid (GLA) in Rhizomucor pusillus AUMC 11616.A and Mucor circinelloides AUMC 6696.A isolated from unusual habitats. Grown for 4 days at 28°C, shaking at 150 rpm, the maximum fungal biomass for AUMC 6696.A was 14.6 ± 0.2 g/L with arginine and 13.68 ± 0.1 g/L with asparagine, when these amino acids were used as single nitrogen sources, while AUMC 11616.A maximum biomass was 10.73 ± 0.8 g/L with glycine and 9.44 ± 0.6 g/L with valine. These were significantly higher than the ammonium nitrate control (p < 0.05). The highest levels of TFA were achieved with glycine for AUMC 11616.A, 26.2 ± 0.8% w/w of cell dry weight, and glutamic acid for AUMC 6696.A, 23.1 ± 1.3%. The highest GLA yield was seen with proline for AUMC 11616.A, 13.4 ± 0.6% w/w of TFA, and tryptophan for AUMC 6696.A, 12.8 ± 0.3%, which were 38% and 25% higher than the ammonium tartrate control. The effects of environmental factors such as temperature, pH, fermentation time, and agitation speed on biomass, total lipids, TFA, and GLA concentration of the target strains have also been investigated. Our results demonstrated that nitrogen assimilation through amino acid metabolism, as well as the use of glucose as a carbon source and abiotic factors, are integral to increasing the oleaginicity of tested strains. Few studies have addressed the role of amino acids in fermentation media, and this study sheds light on R. pusillus and M. circinelloides as promising candidates for the potential applications of amino acids as nitrogen sources in the production of lipids.

“…After harvest, strong wind blowing by a blower, sieving treatment and other physical methods can be used to remove the small and light proportion of scab grains, while the Fusarium and other microorganisms on the grain surface will still be a potential hazard (Machado et al, 2017). The life activities of these harmful microorganisms are the main causes of grain quality loss and spoilage, which interact among themselves, with the grain, and with the environment of the storage facilities, and the mycotoxins continue to be produced during processing, packaging, distribution, and storage of food products at suitable temperature and humidity (Bhatnagar et al, 2006;Ortega et al, 2019;Pereira et al, 2014). The presence of mycotoxins in crops and animal products is a serious problem globally and have a great influence on the people's daily life that calls for global concern (Murshed et al, 2022;Lima et al, 2022).…”

Fusarium Head Blight (FHB) of wheat and small grain cereals caused by Fusarium graminearum and other Fusarium species is an economically cereal disease worldwide. Fusarium infections results in reduced yields and mycotoxin contamination of the grain, and the research on the toxin production and growth control of Fusarium is the key to prevent and control of mycotoxin contamination in wheat. In this study, the molecular identification of toxigenic potential and gas fumigation control of typical Fusarium strains isolated from FHB-infected wheat were studied. The results showed that the consequences of molecular identification of toxigenic potential were consistent with the actual production of toxins, which can be used for rapid identification of fungal toxicity. And the effects of the gas fumigants were different. Chlorine dioxide could kill Fusarium spores and mycelium in a short time (0.5 h) at relatively low concentration (300 ppm), while ozone could only kill Fusarium spores and had no obvious inhibitory effect on the growth of mycelium, even at a concentration of 1400 ppm. Taken together, gaseous ClO 2 could significantly inhibit the growth of Fusarium, and it's an ideal fumigant used to control this fungal contamination during the postharvest storage of grain.
