A novel strain DCY105T was isolated from soil collected from the rhizosphere of ginseng (Panax ginseng), in Gochang, Re-public of Korea. Strain DCY105T is Gram-reaction-negative, white, non-motile, non-flagellate, rod-shaped and aerobic. The bacteria grow optimally at 30°C, pH 6.5–7.0 and in the absence of NaCl. Phylogenetically, strain DCY105T is most closely related to Achromobacter marplatensis LMG 26219T (96.81%). The DNA G+C content of strain DCY105T was 64.4 mol%. Ubiquinone 8 was the major respiratory quinone, and phosphatidylethanolamine, phosphatidylglycerol, and dipho-sphatidylglycerol were amongst the major polar lipids. C16:00, C8:03OH and iso-C17:03OH were identified as the major fatty acids present in DCY105T. The results of physiological and biochemical tests allowed strain DCY105T to be differentiated phenotypically from other recognized species belonging to the genus Achromobacter. Therefore, it is suggested that the newly isolated organism represents a novel species, for which the name Achromobacter panacis sp. nov. is proposed with the type strain designated as DCY105T (=CCTCCAB 2015193T =KCTC 42751T).

Abstract

In recent years, kidney cancer has become one of the most serious medical issues. Kidney cancer is treated with a variety of active compounds that trigger genes that cause cancer. We identified in our earlier research that isoquercitrin (IQ) can activate PIK3CA, IGF1R, and PTGS2. However, it has a very low bioavailability because of its lower solubility in water. So, we utilized sub-merge fermentation technology with two well-known probiotics, Lactobacillus acidophilus and Bacillus subtilis, as a microbial source and mulberry fruit extract as a substrate, which has a high IQ level to improve IQ yield. Furthermore, we compared the total phenolic, flavonoid, and antioxidant contents of fermented and non-fermented samples, and we found that the fermented samples had greater levels than non-fermented sample. In addition, the high-performance liquid chromatography (HPLC) results showed that the fermented mulberry fruit extract from B. subtilis and L. acidophilus showed higher IQ values (190.73 ± 0.004 μg/ml and 220.54 ± 0.007 μg/ml, respectively), compared to the non-fermented samples, which had IQ values (80.12 ± 0.002 μg/ml). Additionally, at 62.5 µg/ml doses of each sample, a normal kidney cell line (HEK 293) showed higher cell viability for fermented and non-fermented samples. Conversely, at the same doses, the fermented samples of L. acidophilus and B. subtilis in a kidney cancer cell line (A498) showed an inhibition of cell growth around 36% and 31%, respectively. Finally, we performed RT and qRT PCR assay, and we found a significant reduction in the expression of the PTGS2, PIK3CA, and IGF1R genes. We therefore can conclude that the fermented samples have a higher concentration of isoquercitrin, and also can inhibit the expression of the genes PTGS2, PIK3CA, and IGF1R, which in turn regulates kidney cancer and inflammation.
