What bacterial strain is isolated in the healthy 10-day-old variety of maize with a high sugar content?
Elizabethkingia endophytica Elizabethkingia endophytica is a slightly yellow Gram-stain-negative rod-shaped bacterial strain isolated from the stem of healthy 10-day-old sweet corn ("Zea mays"). A comparison of the 16S rRNA gene sequence of the isolate showed 99.1, 97.8, and 97.4% similarity to the 16S rRNA gene sequences of the type strains of "Elizabethkingia anophelis", "Elizabethkingia meningoseptica" and "Elizabethkingia miricola", respectively. DNA-DNA hybridization indicated that the strain is representative of a new species.
Dictyoglomus thermophilum Dictyoglomus is a genus of bacterium, given its own phylum, called the Dictyoglomi. This organism is extremely "thermophilic", meaning it thrives at extremely high temperatures. It is "chemoorganotrophic", meaning it derives energy by metabolizing organic molecules. This organism is of interest because it elaborates an enzyme, xylanase, which digests xylan, a heteropolymer of the pentose sugar xylose. By pretreating wood pulp with this enzyme, paper manufacturers can achieve comparable levels of whiteness with much less chlorine bleach.
