Bacterial gliding is a process whereby a bacterium can move under its own power. This process does not involve the use of flagella, which is a more common means of motility in bacteria.[1] For many bacteria, the mechanism of gliding is unknown or only partially known, and it seems likely that in fact different bacteria use distinct mechanisms to achieve what is currently referred to as gliding. Gliding is prominent in cyanobacteria, myxobacteria and the cytophaga-flavobacteria.
The only understood mechanism involves using type IV pili in such bacteria as Pseudomonas aeruginosa and Myxococcus xanthus. In addition, for Myxococcus xanthus A-motility (one of the two motility mechanisms this bacterium has) two other mechanisms have been proposed, one involving ejection of a polysaccharide slime from nozzles at either end of the body [2] and the other using "focal adhesion complexes" distributed along the cell body.[3]

- Gramella planctonica sp. nov., a zeaxanthin-producing bacterium isolated from surface seawater, and emended descriptions of Gramella aestuarii and Gramella echinicola.
- Shahina M1, Hameed A, Lin SY, Lee RJ, Lee MR, Young CC.Author information 1Department of Soil & Environmental Sciences, College of Agriculture and Natural Resources, National Chung Hsing University, Taichung, 402, Taiwan.AbstractA Gram-stain negative, strictly aerobic, zeaxanthin-producing, rod-shaped, non-spore-forming bacterial strain which is motile by gliding, designated CC-AMWZ-3(T), was isolated from surface seawater off coastal Kending, Taiwan. Strain CC-AMWZ-3(T) was found to share 93.3 % and 96.0-92.4 % pairwise 16S rRNA gene sequence similarity to Gramella echinicola KMM 6050(T) and other Gramella species, respectively, and formed distinct phyletic lineage during phylogenetic analysis. The major fatty acids were identified as C16:0, iso-C15:0, anteiso-C15:0, C16:1 ω6c and/or C16:1 ω7c and iso-C17:1 ω9c and/or C16:0 10-methyl. Polar lipids were found to include phosphatidylethanolamine, six unidentified lipids and three unidentified aminolipids. The DNA G+C content was determined to be 40.6 mol%. Menaquinone-6 was the sole respiratory quinone identified and triamine-sym-homospermidine was the predominant polyamine. Based on the polyphasic characteristics that are in line with those of Gramella species, in addition to distinguishing phylogenetic and phenotypic features, strain CC-AMWZ-3(T) appears to represent a novel species of the genus Gramella, for which the name Gramella planctonica sp. nov. (type strain CC-AMWZ-3(T) = JCM 18807(T) = BCRC 80553(T)) is proposed. In addition, emended descriptions of the species Gramella aestuarii and Gramella echinicola are also proposed.

- Characterization of a multi-function processive endoglucanase CHU_2103 from Cytophaga hutchinsonii.
- Zhang C1, Wang Y, Li Z, Zhou X, Zhang W, Zhao Y, Lu X.Author information 1State Key Laboratory of Microbial Technology, School of Life Science, Shandong University, Jinan, 250100, China.AbstractCytophaga hutchinsonii is a Gram-negative gliding bacterium which can efficiently degrade crystalline cellulose by an unknown strategy. Genomic analysis suggests the C. hutchinsonii genome lacks homologs to an obvious exoglucanase that previously seemed essential for cellulose degradation. One of the putative endoglucanases, CHU_2103, was successfully expressed in Escherichia coli JM109 and identified as a processive endoglucanase with transglycosylation activity. It could hydrolyze carboxymethyl cellulose (CMC) into cellodextrins and rapidly decrease the viscosity of CMC. When regenerated amorphous cellulose (RAC) was degraded by CHU_2103, the ratio of the soluble to insoluble reducing sugars was 3.72 after 3 h with cellobiose and cellotriose as the main products, indicating that CHU_2103 was a processive endoglucanase. CHU_2103 could degrade cellodextrins of degree of polymerization ≥3. It hydrolyzed p-nitrophenyl β-D-cellodextrins by cutting glucose or cellobiose from the non-reducing end. Meanwhile, some larger-molecular-weight cellodextrins could be detected, indicating it also had transglycosylation activity. Without carbohydrate-binding module (CBM), CHU_2103 could bind to crystalline cellulose and acted processively on it. Site-directed mutation of CHU_2103 demonstrated that the conserved aromatic amino acid W197 in the catalytic domain was essential not only for its processive activity, but also its cellulose binding ability.

- Aquimarina pacifica sp. nov., isolated from seawater of South Pacific Gyre.
- Zhang Z1, Yu T, Xu T, Zhang XH.Author information 1Ocean University of China.AbstractA Gram-stain-negative, rod-shaped, non-flagellated, strictly aerobic bacterium with gliding motility, designated strain SW150T, was isolated from surface seawater of the South Pacific Gyre (39°19' S, 139°48' W) during the Integrated Ocean Drilling Program (IODP) Expedition 329. Optimal growth occurred in the presence of 2-4 % (w/v) NaCl, at pH 7-8 and at 28-30 C. The dominant fatty acids were iso-C15:0, iso-C17:0 3-OH, iso-C15:1 G, C16:1 ω6c and/or C16:1 ω7c and 10-methyl C16:0 and/or iso-C17:1 ω9c. The polar lipids of strain SW150T comprised phosphatidylethanolamine, three unknown polar lipids and one unknown aminolipid. The major respiratory quinone was MK-6. The DNA G+C content of strain SW150T was 33.8 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that the novel strain was related most closely to Aquimarina macrocephali JAMB N27T and A. muelleri KMM 6020T with 97.8 % and 96.8 % sequence similarities, respectively. The DNA-DNA hybridization estimate values were 21.00 % ± 2.33 between strain SW150T and A. macrocephali JAMB N27T and 20.60 % ± 2.32 between strain SW150T and A. megaterium XH134T. On the basis of polyphasic analyses, strain SW150T represents a novel species of the genus Aquimarina, for which the name Aquimarina pacifica sp. nov. is proposed. The type strain is SW150T (=JCM 18214T =CGMCC 1.12180T).
