Description: English: Bacillus subtilis mass-swarming outwards on a gel substrate from the mother colony visible at the top middle. Time in the lower right is counted in H:M from inoculation, and swarming started at 11:35 (256 minutes before this picture was taken). The swarming dendrites are preceded by a circular ring of surfactant produced by the bacteria. Français : Migration en masse de Bacillus subtilis sur gelose à partir de la colonie mère en haut au centre. Le temps est indiqué en H:M depuis l'inoculation, la migration ayant commencé à 11:35 (soit 256 minutes avant cette image). Les dendrites formées par les bactéries sont précédées d'un anneau d'un surfactant produit par B. subtilis. Deutsch: Schwärmen von Bacillus subtilis auf Agar ausgehend vom kreisförmigen Inokulum in der Mitte oben (Durchmesser ca. 4mm). Die Zeit unten rechts (in Stunden:Minuten) zählt ab Inokulation, das Schwärmen selbst hat erst um 11:35 begonnen (d.h. 256 Minuten vor diesem Bild). Die ringförmige Struktur 2-3mm vor den Spitzen der verästelten Arme des Schwarms markiert die Ausbreitung von Tensiden, die B. subtilis produziert. Date: 17 July 2015. Source: Own work.

Description: English: Bacteria of the species /Bacillus subtilis/ were inoculated at the center of a dish with gelose containing nutrients. The bacteria start mass-migrating outwards about twelve hours after inoculation, forming dendrites which reach the border of the dish (diameter 90mm) within a few hours. Two days after inoculation the number of bacteria has increased so much that they diffuse light significantly and appear white. This picture was taken against a lightsource to make the dendrites (white branched structures) clearly stand out.Français : Des bactéries (Bacillus subtilis) déposées au centre d'une coupelle à la surface d'un gel contenant des nutriments, se mettent à migrer en masse vers l'extérieur environ douze heures après inoculation. Le bord de la coupelle (diamètre 90mm) est atteint en quelques heures. Environ un jour plus tard le nombre d'individus a augmenté au point de rendre les dendrites semi-opaques. Elles apparaissent blanches dans cette photographie à contre-jour.Deutsch: Bactérien (Bacillus subtilis) schwärmen circa zwölf Stunden nach Inokulation auf einem geeigneten Nährboden auswärts und erreichen den Rand der Schale (Durchmesser 90mm) innerhalb von wenigen Stunden. Ungefähr einen Tag darauf hat sich die Zahl der Individuen derart erhöht, dass die Schwarm-Dendriten milchig weiss erscheinen und sich in diesem Foto im Gegenlicht klar abzeichnen.

Description: English: This photomicrograph of a Leifson flagella-stained specimen, revealed the presence of a single, flagellated, Bacillus subtilis bacterium. The use of a special flagellar staining process enabled visualization of the organisms’ peritrichous flagellae, which are invisible, when processed using Gram-stain technique, and observed under a light microscope. B. subtilis is a Gram-positive, endospore-forming bacterium that is present throughout the environment, including the gastrointestinal tract of ruminants and humans. Date: 1977.

Description: English: Figure Caption: The Bacillus subtilis (Stage I) in vegetative growth is in unfavorable conditions, so it begins the process of sporulation. Examples of unfavorable conditions are an environment that lacks the required nutrients, is too hot, or too cold. Asymmetric (unequal) division occurs from the tightening of the Z-ring (Stage II). The Z-ring is multiple FtsZ proteins assembled into a ring that depolymerizes to cause an inward constriction, which will form the septum that results in two daughter cells. The mother cell, which is the bigger of the two daughter cells, engulfs the pre-spore (Stage III). Next, the cortex (Stage IV) and the coat (Stage V) form around the spore. The cortex is made of peptidoglycan and the coat is composed of several layers of specific proteins. Once the spore is mature, the cell lyses (Stage VI and VII). Thus, a free endospore is formed that can withstand harsh environments. This endospore can later germinate into a vegetative cell. Vegetative cycle occurs in favorable conditions, such as nutrient abundance and a moderate temperature. This is a cycle of medial division and growth creating more vegetative Bacillus subtilis. [1].
