Introduction. Acetic acid bacteria (AAB), first described as "vinegar bacteria" by Louis Pasteur over 150 years ago, are an important and diverse group of bacteria involved in the production of fermented foods and beverages, especially known for their production of acetic acid (ethanoic acid) in the making of vinegar (Hutkins, 2006; Pasteur, 1864).
Bacterial wilt pathogen Ralstonia solanacearum (Smith, 1896; Yabuuchi et al., 1995) is a gram negative, rod shaped, β-proteobacteria, nonsporulating, aerobic, soil-borne, motile bacterium with a polar tuft of flagellum. It causes wilt diseases in plants by invading through xylem vessels (Genin, 2010). It colonizes the root surface and then
These bacteria are facultative anaerobes, nonspore-forming, nonmotile and motile, and rod-shaped, which ferment lactose with acid and gas formation when incubated at 35–37 °C. The biochemical test was designed to meet the definition to differentiate this member from other members of the family Enterobacteriaceae, as detailed later in this ...
In dairy, several membrane types are used across applications. For milk preservation, we use ceramic membrane filtration systems. That's when we move 1-meter rods, with narrow flow tunnels inside, throughout a milk product to remove unwanted microorganisms, such as bacterial spores.
Bacteria (singular-bacterium) are the microscopic unicellular and prokaryotic organisms. It is also known as a microbe. The term bacteria were first coined by F.J. Cohn in 1854. Bacteria come from the Greek word manning rod. It was discovered by Antonie Von Leeuwenhoek in 1976. It has a plant like cell-wall and autotrophic mode of nutrition.
The average diameter of spherical bacteria is 0.5-2.0 µm. For rod-shaped or filamentous bacteria, length is 1-10 µm and diameter is 0.25-1 .0 µm. E. coli, a bacillus of about average size is 1.1 to 1.5 µm wide by 2.0 to 6.0 µm long. Spirochaetes …
Basic Morphology. H. pylori in vivo and under optimum in vitro conditions is an S-shaped bacterium with 1 to 3 turns, 0.5 ×5 μm in length, with a tuft of 5 to 7 polar sheathed flagella (40, 51).This morphology has been correlated with maximum in vitro motility ().The majority of helicobacters possess this basic morphology of an S shape with polar, sheathed flagella, though variations in size ...
The growth mechanism of bacteria in textile fabrics is essential to be known, to effectively inhibit their growth (Puvvada et al. 2019).Figure 2 shows the schematic representation of bacterial growth mechanism in textile fabrics. Generally, textiles, clothes and apparels are made up of synthetic or natural fibres, which are composed of polymers (Paderes et al. 2017).

These bacteria, which are commonly isolated on nonselective growth media, are often referred to as the residential bacteria, background flora, total bacterial count, total viable count, heterotrophic plate count, aerobic plate count, or standard plate count (Nivens and others 2009). However, the identity of these bacteria and their impact on ...
