It has been Pseudomonas cocovenenans van Damme et al. Introduction: Bongkrekic acid (BA) has a unique mechanism of toxicity among the mitochondrial toxins: it inhibits adenine nucleotide translocase (ANT) rather than the electron transport chain.Burkholderia gladioli is a species of aerobic gram-negative rod-shaped bacteria [1] that causes disease in both humans and plants., 2017 ). Orchidaceae (the orchid family) is a diverse and widespread family of flowering plants that often have fragrance and ornamental qualities. Based on the 16S rRNA sequences, DNA‐DNA homology values, cellular lipid and fatty acid composition, and phenotypic characteristics, a new genus Burkholderia is proposed for the RNA homology group II of genus Pseudomonas.g.
