Select your answer for: Which of these is characterized as gram-positive__________?
Show answer

Answer: B. Corynebacterium

Explanation

Corynebacterium is characterized as a Gram-positive bacterial genus. Gram-positive bacteria retain crystal violet stain during laboratory Gram staining. This classification separates them from major Gram-negative plant pathogens. Bacterial cell wall composition determines their reaction to Gram staining. Corynebacterium species can be animal pathogens or plant disease agents. Microbiology uses staining techniques to identify and classify bacterial isolates.

Plant pathologists identify bacterial traits to diagnose crop diseases accurately. Laboratory testing ensures correct selection of bactericides for disease control. Understanding bacterial cell wall structure aids in antibiotic research. Xanthomonas represents a well-known genus of Gram-negative plant bacteria. Pseudomonas species are typically Gram-negative rods with polar flagella. Erwinia belongs to the Gram-negative family causing soft rots in crops.
