“…Many studies have proved that gram-positive bacteria are relatively easier to kill than gram-negative bacteria. Sugarcane molasses essential oil is stronger against Gram-positive bacteria (23.07 ± 0.0404 mm) than Gram-negative bacteria (17.73 ± 0.839–23.07 ± 3.101 mm) [21] . The antibacterial activity of citronella essential oil obtained by different methods against Gram-positive bacteria (10.33 ± 0.29–26.17 ± 0.29 mm) is higher than that against Gram-negative bacteria (7.67 ± 0.29–11.67 ± 0.29 mm) [36] .…”

“…Combined with SEM and TEM, bacteria's surface and internal morphology can be displayed more completely. With some modifications, SEM and TEM were used to image the surface structure of bacteria, as mentioned earlier [21] . In brief, 5 mg/mL samples were mixed with 1 × 10 7 CFU/mL Escherichia coli and Staphylococcus aureus at 37℃ for 6 h. Next, the mixture was centrifuged at 8000 rpm for 5 min, and the supernatant was poured out.…”

“…In this study, the paper disk diffusion method was employed to assess the antibacterial effects of the three SLPs (Zhang et al, 2020b). The test bacterial strains (1 × 10 6 CFU/mL) were diluted with sterile physiological saline, and 50 μL of the diluted bacterial suspension was uniformly spread on Mueller-Hinton agar.…”

Three new polysaccharides (SLP-50, SLP-70, and SLP-90) were fractionated successively by gradient concentrations of ethanol. This study aimed to investigate the initial structural characterization and bioactivities of these sugarcane leaves polysaccharides (SLPs) obtained by ultrasound-assisted extraction. The results, which were further validated by IR spectrometry, revealed that the three SLPs contained uronic acids, proteins, and sulfate groups in addition to carbohydrate. SLP-50 (36.40 kDa), SLP-70 (12.97 kDa), and SLP-90 (3.52 kDa) were acidic heteropolysaccharides mainly comprised of mannose (Man), rhamnose (Rha), glucuronic acid (Glc A), galacturonic acid (Gal A), galactose (Gal), glucose (Glc), xylose (Xyl), and arabinose (Ara), in different molar ratios. SLP-90 exhibited higher antioxidant capacity than SLP-50 and SLP-70. In vitro, all fractions showed significant hypoglycemic potential and antibacterial activity against Gram-positive and Gram-negative bacteria. The IC 50 values of SLP-50, SLP-70, and SLP-90 were 0.11, 0.05, and 0.67 mg/mL on α-glucosidase, respectively, which were significantly lower than that of acarbose (0.80 mg/mL). These findings could provide a reference for developing and applying SLP-based functional foods.

This study investigated the impact of ultrasonic extraction (UE) on the structure and in vitro antibacterial activity of polysaccharides from sugarcane leaves (SLW). Native sugarcane leaf polysaccharides were treated with ultrasound (480 W) for 3 h to yield sugarcane leaf polysaccharides (SLU). Compared to SLW (33.59 kDa), the molecular weight of SLU (13.08 kDa) was significantly decreased, while the monosaccharide composition of SLU was unchanged. The results of SEM and XRD indicated that UE significantly changed the surface morphology of SLW and destroyed its inner crystalline structure. In vitro experiments showed that SLU had stronger antibacterial activity. These findings revealed that UE treatment could alter the tertiary structure of SLW but had no impact on its primary structure. Furthermore, the antibacterial activity of SLW could be greatly enhanced after UE treatment. As a bioactive additive, SLU has great application potential in functional foods, cosmetics, and pharmaceuticals.
