“…We did not notice a size effect on LAB survival as we did in yeast, possibly because the differences in size among bacteria were very small (from 0·5 to 1 μ m diameter for O. oeni , P. cerevisiae and L. mesenteroides cells to 0·5–1 × 1·2–8 μ m for L. brevis , L. hilgardii , L. mali , L. paracasei and L. plantarum ) (Dicks and Holzapfel ; Hammes and Hertel ; Holzapfel et al . ,b). Cell morphology did not explain the survival rate differences obtained with our results.…”

“…The cell wall composition data were obtained from Bergey's Manual of Systematic Bacteriology (Dicks and Holzapfel ; Hammes and Hertel ; Holzapfel et al . ,b). Zhao and Zhang found that malolactic species O. oeni and L. brevis displayed wider viability after freeze‐drying when frozen at −65°C than at −20°C (Zhao and Zhang , ).…”

“…The presence of mreB correlates with rod shape, with the special cases of Leuconostoc spp. and Oenococcus that can display both rod and ovoid morphologies (Dicks et al ., ; Dicks and Holzapfel, ; Holzapfel et al ., ). These data support the notion that cocci have evolved from a rod‐shaped ancestor (Siefert and Fox, ; Gupta, ; Koch, ) and provide new insights on how this event may have happened inside a phylogenetically closely related group of bacteria.…”

SummaryStreptococcus pneumoniae is an oval-shaped Grampositive coccus that lives in intimate association with its human host, both as a commensal and pathogen. The seriousness of pneumococcal infections and the spread of multi-drug resistant strains call for new lines of intervention. Bacterial cell division is an attractive target to develop antimicrobial drugs. This review discusses the recent advances in understanding S. pneumoniae growth and division, in comparison with the best studied rod-shaped models, Escherichia coli and Bacillus subtilis. To maintain their shape, these bacteria propagate by peripheral and septal peptidoglycan synthesis, involving proteins that assemble into distinct complexes called the elongasome and the divisome, respectively. Many of these proteins are conserved in S. pneumoniae, supporting the notion that the ovococcal shape is also achieved by rounds of elongation and division. Importantly, S. pneumoniae and close relatives with similar morphology differ in several aspects from the model rods. Overall, the data support a model in which a single large machinery, containing both the peripheral and septal peptidoglycan synthesis complexes, assembles at midcell and governs growth and division. The mechanisms generating the ovococcal or coccal shape in lactic-acid bacteria have likely evolved by gene reduction from a rod-shaped ancestor of the same group.

“…Bacteria from dairy milk or meat were also found such as Lactobacillus (Hammes and Hertel 2009), Lactococcus (Teuber 2009), Leuconostoc (Holzapfel et al 2009), and Brevibacterium (Brennan et al 2002). Bacterial biodiversity in the SC appears related to the occupational activities due to the origin of waste (domestic environment) as well as the presence of workers.…”

Waste sorting activities are source of occupational bioaerosol exposures that are associated with several health disorders. New analytical tools, based on next-generation sequencing (NGS) technologies, provide powerful methods to assess the microbial composition of bioaerosols. The objectives of the study were (i) to assess the feasibility and the repeatability of NGS-based biodiversity measurements and (ii) to study the microbial biodiversity using NGS in bioaerosols emitted in a waste sorting plant (WSP). Three stationary parallel samples were collected in a sorting cabin using closed-face cassettes equipped with polycarbonate membranes. Bacterial and fungal diversity was assessed by sequencing 16S and 18S rDNA genes using either Illumina sequencing or 454 pyrosequencing methods. At sampling point, airborne bacteria were dominated by Proteobacteria, Firmicutes, and Actinobacteria with prevailing genera assigned to unclassified Enterobacteriaceae, Staphylococcus, Acinetobacter, Leuconostoc, Pseudomonas, and Lactobacillus. Airborne fungi were dominated by Ascomycota with prevailing genera assigned to Penicillium, Aspergillus, Rhizopus, Wallemia, and Hemicarpenteles. The NGS biodiversity measurements revealed a higher biodiversity bioaerosols that previously reported for WSP in studies carried out using culture methods followed by identification of microorganisms. These results provide the first survey about taxonomic biodiversity in bioaerosols from WSPs using high-throughput sequencing.
