Gram-negative bacteria exhibit lipopolysaccharides (LPSs) on their outer membrane surface. LPS is considered one of the most potent bacterial virulence factors. Here we report the elucidation of the LPS O-chain structure isolated from Burkholderia fungorum, a bacterium isolated from the white-rot fungus Phanerochaete chrysosporium that can act as a pathogen for plants and domesticated animals. The structure was determined by the employment of detailed chemical and NMR spectroscopy analyses as the following.

Crude glycerol (CG), a major biodiesel production by-product, is the focus of ongoing research to convert it into polyhydroxyalkanoate (PHA). However, few bacterial strains are capable of efficiently achieving this conversion. Here, 10 PHA-producing strains were isolated from various media.

The ubiquitous presence, potential toxicity, and persistence of 2-ethylhexyl diphenyl phosphate (EHDPP) in the environment have raised significant concerns. In this study, we successfully isolate a novel microbial consortium, named 8-ZY, and we demonstrate its remarkable ability to degrade EHDPP using an extremely low concentration of the inoculate. A total of 11 degradation metabolites were identified, including hydrolysis, hydroxylated, methylated, glucuronide-conjugated, and previously unreported byproducts, enabling us to propose new transformation pathways.

Endophytes are bacteria that inhabit host plants for most of their life cycle without causing harm. In the study, 15 endophytic bacteria were isolated from 30 forage Sorghum plants and assessed for various plant growth-promoting (PGP) traits, such as phosphate solubilization, 1-aminocyclopropane-1-carboxylic acid (ACC) deaminase activity, ammonia production, siderophore production, gibberellic acid production, Indole-3-acetic acid (IAA) production, and zinc solubilization. One isolate, JJG_Zn, demonstrated multiple PGP activities and was identified as Enterobacter sp.

The complex (BCC) is a group of Gram-negative bacteria that cause opportunistic infections, most notably in people with cystic fibrosis (CF), and have been associated with outbreaks caused by contaminated medical products. Antimicrobial susceptibility testing (AST) is often used to guide treatment for BCC infections, perhaps most importantly in people with CF who are being considered for lung transplant. However, recent studies have highlighted problems with AST methods.

Background: Glanders and melioidosis are contagious zoonotic diseases caused by Burkholderia mallei and B. pseudomallei, respectively. Bacterial isolation and polymerase chain reaction (PCR) have been used to detect these bacteria in animals suspected of infection; however, both methods require skilled experimental techniques and expensive equipment.
