“…Degradation of bacterial proteins was also observed in bacteria treated with other antimicrobials, such as lactic acid (Wang et al, 2015) and the essential oil from Juniperus rigida leaves (Meng et al, 2016). The present findings suggested K. galanga essential oil has remarkable effects on bacterial proteins, decreasing cellular protein amounts by permeating and disturbing the cell membrane.…”

“…In recent years, a plethora of essential oils have been isolated from multiple organs of various aromatic plants by hydro-distillation or supercritical CO2 fluid extraction (Meng et al, 2016). Nowadays, an increasing amount of attention has been cast on essential oils and their various components, due to their various biological activities used in healthcare, food, or medicine, especially antioxidant, antimicrobial (Ud-Daula et al, 2016), antifungal (Mehrparvar et al, 2016), anxiolytic (Zhang et al, 2016a), antimycotoxigenic (Rasooli et al, 2008), and antitumor activities (Gong et al, 2016).…”

Kaempferia galanga L. is a traditional herbal medicine with high essential oil content. Gas chromatography-mass spectrometry (GC-MS) detected 25 different compounds in K. galanga essential oil, representing 95.98% of the total oil. The antibacterial activity of the essential oil was measured by the microtiter broth dilution method, and minimum inhibitory concentrations (MICs) against the three pathogenic bacterial strains Escherichia coli, Salmonella typhimurium and Staphylococcus aureus were 5, 1, and 2 mg/mL, respectively. The antibacterial mechanisms of K. galanga essential oil were further explored, and massive nucleotide and protein leakage demonstrated that it caused membrane disruption in the pathogens. SDS-PAGE confirmed the disruptive action of the essential oil on the cytoplasmic membrane. Moreover, the essential oil-induced cell wall and membrane damage was observed by scanning electron microscopy. These findings indicated K. galanga essential oil might constitute a candidate for developing new food preservatives and pharmaceuticals.

“…On the other hand, the SDS‐PAGE patterns of total proteins of A. acidoterrestris treated with the phenolic compound at MBC level (lane 4 and 5) were lighter than the control, which further suggested that the cell membrane was destroyed and the membrane permeability increased, resulting in the inhibition of the growth of A. acidoterrestris and the decrease in cellular proteins content. In addition, the phenolic compound may also interfere with synthesis of bacterial cell proteins (Meng et al ., ). It has been reported that carvacrol inhibited the synthesis of flagellin in Escherichia coli O157:H7 significantly (Burt et al ., ).…”

The aim of this study was to investigate the antibacterial activity and mechanism of cinnamic acid and chlorogenic acid against Alicyclobacillus acidoterrestris. Minimum inhibitory concentrations of cinnamic acid and chlorogenic acid were 0.375 and 2.0 mg mL À1 , and the minimum bactericidal concentrations were 0.50 and 4.0 mg mL À1 , respectively. The apple juice ingredients had little influence on the inactivation of A. acidoterrestris. After treatment with cinnamic acid and chlorogenic acid, the morphology of A. acidoterrestris cells were severely destroyed; the leakage of nucleic acids and proteins increased significantly. SDS-PAGE investigation of bacterial proteins proved that the loss of soluble proteins was obvious as well. These results demonstrated that cinnamic acid and chlorogenic acid exerted their antibacterial activity mainly by an action mode of membrane disruption. This study provides an alternative method for the control of A. acidoterrestris-related spoilage in the fruit juice/beverage industry.

The allelopathic effects of Juniperus rigida litter aqueous extract (LE) on wheat and Pinus tabuliformis were studied, as well as the physiological responses to the extract. High concentration LE (0.10 g Dw/ml) significantly inhibited the seed germination and seedling growth in receptor plants. The chlorophyll content and root activity in the wheat seedlings were reduced significantly across all treatments; however, those were more prominently reduced at high concentration (0.10 g Dw/ml) but received little stimulation at low concentration (0.025 g Dw/ml) in P. tabuliformis. The content of malonaldehyde (MDA) increased with increasing concentrations of LE, except at 0.025 g Dw/ml. Activities of antioxidant enzymes (POD, CAT and SOD) in receptor plants were all significantly inhibited at high concentrations but stimulated at low concentrations. These results demonstrate that the aqueous extract from J. rigida litter has allelopathic potential. Various phenolic compounds were identified in litter aqueous extract and litter ethanol extract by HPLC. The phenolic compound content in the aqueous extract was significantly lower than that in the ethanol extract. Chlorogenic acid and podophyllotoxin were the predominant phenolic compounds in both types of litter extracts. These findings suggest that the seed germination and seedling growth of P. tabuliformis and wheat would be inhibited when planted near large amounts J. rigida litter.
