What is the colony morphology of Bacillus?
Bacillus anthracis — Colony Characteristics Colonies are nonhemolytic, flat or slightly convex with irregular edges and ground-glass appearance. There are often comma shaped projections from the colony edge producing a “Medusa-head” colony. Colonies have a sticky consistency when manipulated with a loop.
What is the colony morphology of Bacillus subtilis?
Bacillus subtilis is a typical germ, which is rod-shaped and Gram-positive. When cultured on ordinary nutrient agar, the morphology circular colony of this bacteria is rough, opaque, fuzzy white or slightly yellow with jagged edges [1, 7].
What is the expected colony morphology for Bacillus mycoides?
mycoides is distinguished from a number of other Bacillus species in the unusual morphology of the colonies it forms when grown on agar plates. B. mycoides forms white opaque colonies that are characteristically hairy in appearance (often referred to as “rhizoid”).
What is the colony morphology of Serratia marcescens?
marcescens strains from the cactus plant and silkworms. Both two strains formed red, smooth, convex, entire and round colonies on nutrient agar. Classical bacteriological tests showed that they were gram-negative, rod shaped and motile organisms.
What is microbiology morphology?
morphology, in biology, the study of the size, shape, and structure of animals, plants, and microorganisms and of the relationships of their constituent parts.
How is Bacillus cereus arranged?
The bacilli are arranged in chains, as the cells divide in one plane.
What is the colony color for Serratia marcescens?
red colonies
DNase agar, which contains DNA, and DTC agar, which contains cephalothin (to which most strains of Serratia are resistant), are also used for isolation. On blood agar and some other media, S. marcescens produces red colonies. As the colonies grow, the colour intensifies.
What is the morphology of Serratia rubidaea?
Serratia rubidaea MICROSCOPIC APPEARANCE Gram Stain: Gram-negative. Morphology: Straight rods with rounded ends. Size: 0.5-0.8 micrometers by 0.9-2.0 micrometers. Motility: Usually motile by peritrichous flagella. Capsules: None. Spores: None. MACROSCOPIC APPEARANCE
What is the morphology of Bacillus subtilis?
Bacillus subtilisis a typical germ, which is rod-shaped and Gram-positive. When cultured on ordinary nutrient agar, the morphology circular colony of this bacteria is rough, opaque, fuzzy white or slightly yellow with jagged edges [1, 7].
What is the morphology of Serratia liquefaciens?
Serratia liquefaciens Serratia marcescens Serratia odorifera Serratia plymuthica Serratia rubidaea MICROSCOPIC APPEARANCE Gram Stain: Gram-negative. Morphology: Straight rods with rounded ends. Size: 0.5-0.8 micrometers by 0.9-2.0 micrometers. Motility:
What are the characteristics of Serratia Ficaria?
SPECIES Serratia ficaria Serratia fonticola Serratia liquefaciens Serratia marcescens Serratia odorifera Serratia plymuthica Serratia rubidaea MICROSCOPIC APPEARANCE Gram Stain: Gram-negative. Morphology: Straight rods with rounded ends. Size:
