“…Therefore, increasing the protein content in DDG could enhance its overall value [9]. In corn ethanol production, yeast cells are not recycled and are instead incorporated into DDG [10]. Therefore, each fermentation cycle requires the introduction of a new inoculum.…”

Yeast is one of the co-products of ethanol plants, which can be used as a nutritional supplement in animal feed due to its high protein content. Given the importance of yeast contribution to the nutritional properties of DDG (dried distillers’ grains), the aim of this study was to assess how different levels of aeration affect the biomass production and the quality of yeast providing new insights into yeast production, offering an alternative source of income for the corn ethanol industry. For this purpose, yeasts were grown in a fed-batch process, and different concentrations of aeration in the medium were tested, namely 0.5, 1.0, and 1.5 volume of air per volume of wort per minute (v v−1 min−1). At the end of the cellular biomass production process, yeasts grown with 0.5 (v v−1 min−1) aeration in the reactor showed higher biomass formation (19.86 g L−1), cellular yield (g g−1), and a lower formation of succinic acid (0.70 g L−1) and acetic acid (0.11 g L−1). Aeration influenced an increase of 1.0% in the protein content in yeast. In conclusion, lower levels of aeration in the yeast production process enables more efficient sugar utilization for biomass formation and is a potential strategy to increase the protein content and the commercial value of DDG.

This experiment aimed to assess the impact of de cit irrigation on both the quantitative and qualitative yield of forage maize hybrids. The study was structured as a split-plot design, utilizing a randomized complete block design with three replications, where took place at the Agricultural Research Station of Gorgan in the years 2021 and 2022. De cit irrigation was implemented at four different levels as the main plots, which comprised 100%, 75%, 50%, and 25% of the water requirement. These main plots were further subdivided into subplots, consisting of four hybrid varieties, namely SC703, SC704, ZP548, and BK50.The results showed that the highest total biomass (47939 kg ha − 1 ) was obtained under 100% water requirement (control) and SC704 hybrid. The reduction in total biomass for the treatments at 75%, 50%, and 25% of the water requirement, when compared to the control treatment, amounted to 7%, 47.4%, and 79.1%, respectively. De cit irrigation signi cantly affected qualitative traits except for NDF at the level of 1% and increased all quality traits. Accordingly, the highest percentage of CP, NDF, and ADF was obtained by hybrid SC703 with 50% water requirement (by 9.20%), hybrid BK50 under 25% water requirement (by 30.73%), and BK50 with 75% water requirement (by 44.03%). The highest water use e ciency was observed in 75% of the water requirement (7.79 kg m − 3 ). Considering the signi cant reduction in water consumption (1795 m 3 ha − 1 ) achieved with this treatment, it is advisable to recommend irrigation at 75% of the water requirement alongside the cultivation of the SC703 hybrid for forage production in the northern region of Iran.

The reduction in total biomass for the treatments at 75%, 50%, and 25% of the water requirement, when compared to the control treatment, amounted to 7%, 47.4%, and 79.1%, respectively. Deficit irrigation significantly affected qualitative traits except for NDF at the level of 1% and increased all quality traits. Accordingly, the highest percentage of CP, NDF, and ADF was obtained by hybrid SC703 with 50% water requirement (by 9.20%), hybrid BK50 under 25% water requirement (by 30.73%), and BK50 with 75% water requirement (by 44.03%).
