Query: NC_015687:3252233 Clostridium acetobutylicum DSM 1731 chromosome, complete genome
Lineage: Clostridium acetobutylicum; Clostridium; Clostridiaceae; Clostridiales; Firmicutes; Bacteria
General Information: This organism is a benign saccharolytic and proteolytic soil bacterium capable of producing a number of organic solvents (solventogenic bacterium) through fermentation of various organic compounds. The first strains of C. acetobutyricum were isolated by Chaim Weizman during the World War I and used to develop industrial starch-based acetone, butanol and ethanol fermentation processes.
Subject: NC_002488:2502000 Xylella fastidiosa 9a5c, complete genome
Lineage: Xylella fastidiosa; Xylella; Xanthomonadaceae; Xanthomonadales; Proteobacteria; Bacteria
General Information: This strain was derived from a pathogenic strain (8.1b) isolated in 1992 in France that had come from infected twigs derived from the sweet orange strain Valencia in Brazil in the same year. This organism was first identified in 1993 as the causal agent of citrus variegated chlorosis, a disease that affects varieties of sweet oranges. Other strains of this species cause a range of diseases in mulberry, pear, almond, elm, sycamore, oak, maple, pecan and coffee which collectively result in multimillion dollar devastation of economically important plants. Xylella fastidiosa is similar to Xanthomonas campestris pv. campestris in that it produces a wide variety of pathogenic factors for colonization in a host-specific manner including a large number of fimbrial and afimbrial adhesins for attachment. It does not contain a type III secretion system, but possesses genes for a type II secretion system for export of exoenzymes that degrade the plant cell wall and allow the bacterium to colonize the plant xylem.
