Summary: The present study analyzed the composition, bioactive compound contents, and iron bioavailability of sweet sorghum molasses and compared them to sugar cane molasses. The sorghum molasses showed higher levels of proteins, lipids, total dietary fiber, carbohydrates, ash, calcium, total phenolic compounds, and ferritin concentration. This indicates that sorghum molasses is a promising source of minerals and bioactive compounds for human nutrition.

Summary: Open burning of agricultural residues leads to various complications, including particulate matter pollution, soil degradation, and global warming. This study evaluated different agricultural residues (sugarcane bagasse, rice straw, corncob, and sweet sorghum bagasse) and yeast strains (Candida tropicalis, C. shehatae, Saccharomyces cerevisiae, and Kluyveromyces marxianus var. marxianus) for their potential in producing bioethanol and phenylacetylcarbinol (PAC), an intermediate in pharmaceutical production. Among the substrates and yeasts tested, rice straw cultivated with C. tropicalis exhibited significantly higher ethanol concentration (15.3 g L-1) after 24 hours of cultivation. The study also compared the use of whole cells biomass and partially purified pyruvate decarboxylase (PDC) of C. tropicalis for PAC production, and found that the whole cells biomass yielded 68.4% more PAC. This research demonstrates the potential of utilizing lignocellulosic residues for bioethanol and PAC production, which can contribute to environmental mitigation and enhance the bioeconomy.

Summary: This study found that sugarcane aphids can have negative effects on sweet sorghum juice quality, particularly affecting sugar-related traits. Different planting dates and cultivars can influence the resistance or tolerance to aphid damage, with secondary metabolites potentially playing a role in resisting aphids. Tolerant cultivars were able to maintain high concentrations of sugars and certain acids across different environments.

Summary: This study assessed the substrate inhibition and butanol tolerance of Clostridium beijerinckii DSM 6423 in isopropanol-butanol (IB) production by isopropanol-butanol-ethanol (IBE) fermentation from an industrial mixture of sugarcane and sweet sorghum juices. The formulation of a low-cost medium for IB production from industrial juices by C. beijerinckii DSM 6423 was also studied. The results showed that an initial sugar concentration of 40 g/L in the industrial juices had the best kinetic for the fermentation.

Summary: This study aimed to evaluate the effect of sugarcane molasses on the silage quality of sorghum-sudangrass hybrid. The results showed that the addition of molasses improved the dry matter, crude protein, and ash contents of the silage, while decreasing the pH, cellulose, and hemicellulose contents. Therefore, sugarcane molasses can be used as an additive to significantly improve the quality of sorghum-sudangrass silage.

Summary: Amplicon-based sequencing was utilized to address long-ignored gaps in microbiological knowledge about the diversity of microbes present in processing streams at Louisiana sugarcane raw sugar factories. These results support an emerging model where diverse organisms contribute to sugarcane juice degradation, help to contextualize microbial contamination problems faced by raw sugar factories, and will guide future studies on biocontrol measures to mitigate sucrose losses and operational challenges due to exopolysaccharide production.

Summary: This study developed a method to extract aconitic acid from sweet sorghum syrup and evaluated its capability to suppress nematode motility. Aconitic acid was efficiently extracted using acetone:butanol:ethanol mixtures and recovered with a sodium carbonate solution, with an overall efficiency of 86%. However, the inhibitory effect on nematodes may not be solely attributed to aconitic acid, as other components in the sweet sorghum extract may also play a role.

Summary: Processing aids are used in sugarcane processing to reduce contamination from microorganisms and polysaccharides. This study found that sodium hypochlorite may interfere with enzymatic activity, while carbamates and hop extracts have lesser inhibitory effects. The effectiveness of sodium hypochlorite against bacterial strains was limited, while carbamates showed broad-spectrum activity.
