Benzaldehyde as an insecticidal, antimicrobial, and antioxidant compound produced by Photorhabdus temperata M1021
Journal of Microbiology - Tập 53 - Trang 127-133 - 2015
Ihsan Ullah, Abdul Latif Khan, Liaqat Ali, Abdur Rahim Khan, Muhammad Waqas, Javid Hussain, In-Jung Lee, Jae-Ho Shin
The Photorhabdus temperata M1021 secretes toxic compounds that kill their insect hosts by arresting immune responses. Present study was aimed to purify the insecticidal and antimicrobial compound(s) from the culture extract of P. temperata M1021 through bioassay guided fractionation. An ethyl acetate (EtOAc) extract of the P. temperata M1021 exhibited 100% mortality in Galleria mellonella larvae w...... hiện toàn bộ

Hymenobacter daeguensis sp. nov. isolated from river water
Journal of Microbiology - Tập 55 - Trang 253-259 - 2017
Leonid N. Ten, Yeon-Hee Lee, Jae-Jin Lee, Su-Jin Park, Seung-Yeol Lee, Sangkyu Park, Dae Sung Lee, In-Kyu Kang, Hee-Young Jung
A Gram-stain-negative, non-motile, non-spore-forming, rod-shaped, aerobic bacterial strain, designated 16F3Y-2T, was isolated from the Han River, South Korea, and was characterized taxonomically using a polyphasic approach. Comparative 16S rRNA gene sequence analysis showed that strain 16F3Y-2T belonged to the family Cytophagaceae in the phylum Bacteroidetes and was most closely related to ‘Hymeno...... hiện toàn bộ
Effect of Lactobacillus reuteri on the proliferation of Propionibacterium acnes and Staphylococcus epidermidis
Journal of Microbiology - - 2012
Mi-Sun Kang, Jong-Suk Oh, Seok-Woo Lee, Hoi-Soon Lim, Nam-Ki Choi, Seon-Mi Kim
While it is generally accepted that Propionibacterium acnes is involved in the development of acne, other bacteria including Staphylococcus epidermidis have also been isolated from the acne lesion. The interaction between Lactobacillus reuteri, a probiotic bacterium, and acnegenic bacteria is unclear. This study examined the effects of L. reuteri on the proliferation of P. acnes and S. epidermidis...... hiện toàn bộ

EAST1 toxin: An enigmatic molecule associated with sporadic episodes of diarrhea in humans and animals
Journal of Microbiology - Tập 57 - Trang 541-549 - 2019
J. Daniel Dubreuil
EAST1 is produced by a subset of enteroaggregative Escherichia coli strains. This toxin is a 38-amino acid peptide of 4100 Da. It shares 50% homology with the enterotoxic domain of STa and interacts with the same receptor. The mechanism of action of EAST1is proposed to be identical to that of STa eliciting a cGMP increase. EAST1 is associated with diarrheal disease in Man and various animal specie...... hiện toàn bộ
Immunological characterization of monoclonal antibodies used in rapid influenza diagnostic test for detection of the 2009 pandemic influenza A(H1N1)pdm09 infection
Journal of Microbiology - Tập 53 - Trang 166-175 - 2015
Hwajung Yi, Mi-Seon Lee, Joo-Yeon Lee, Hae Kyung Lee, Chun Kang
Since the 2009 pandemic, monoclonal antibodies (mAbs) for rapid influenza diagnostic tests (RIDT) have been developed for specific diagnostics of pandemic viral infection. Most of the mAbs were poorly characterized because of urgency during the pandemic. Further characterization of the mAbs for RIDTs would be beneficial for understanding the immunological properties of the pandemic virus and utili...... hiện toàn bộ
Assessment of conjugal transfer of antibiotic resistance genes in Salmonella Typhimurium exposed to bile salts
Journal of Microbiology - Tập 52 - Trang 716-719 - 2014
Xinlong He, Juhee Ahn
This study was designed to evaluate the transfer potential of antibiotic resistance genes in antibiotic-resistant Salmonella Typhimurium (S. TyphimuriumR) in the presence of bile salts. The resistance of S. TyphimuriumR to ampicillin, kanamycin, and tetracycline was increased by 64-, 64-, and 512-fold, respectively. The highest transfer frequency from S. TyphimuriumR to Escherichia coli was observ...... hiện toàn bộ
Oceanobacillus kimchii sp. nov. Isolated from a traditional Korean fermented food
Journal of Microbiology - Tập 48 - Trang 862-866 - 2011
Tae Woong Whon, Mi-Ja Jung, Seong Woon Roh, Young-Do Nam, Eun-Jin Park, Kee-Sun Shin, Jin-Woo Bae
A moderate halophile, strain X50T, was isolated from mustard kimchi, a traditional Korean fermented food. The organism grew under conditions ranging from 0–15.0% (w/v) NaCl (optimum: 3.0%), pH 7.0–10.0 (optimum: pH 9.0) and 15–45°C (optimum: 37°C). The morphological, physiological, and biochemical features and the 16S rRNA gene sequences of strain X50T were characterized. Colonies of the isolate w...... hiện toàn bộ
The role of carbohydrate-binding module (CBM) repeat of a multimodular xylanase (XynX) from Clostridium thermocellum in cellulose and xylan binding
Journal of Microbiology - Tập 48 - Trang 856-861 - 2011
Thangaswamy Selvaraj, Sung Kyum Kim, Yong Ho Kim, Yu Seok Jeong, Yu-Jeong Kim, Nguyen Dinh Phuong, Kyung Hwa Jung, Jungho Kim, Han Dae Yun, Hoon Kim
A non-cellulosomal xylanase from Clostridium thermocellum, XynX, consists of a family-22 carbohydratebinding module (CBM22), a family-10 glycoside hydrolase (GH10) catalytic module, two family-9 carbohydrate-binding modules (CBM9-I and CBM9-II), and an S-layer homology (SLH) module. E. coli BL21(DE3) (pKM29), a transformant carrying xynX′, produced several truncated forms of the enzyme. Among them...... hiện toàn bộ
