Mature colonies of Nocardia asteroides cultivated on trypticase soy agar. Basic elements you can identify in a colony morphology include the following: Image 1: The image shows the colony morphology of bacteria. The colony morphology of B. subtilis refers to how it appears in large quantities. Find common criteria that are used to characterize bacterial growth; Colony shape Size of the bacterial colony Appearance of the colony surface Consistency/Texture FIG. The organism secretes a keratinase which is capable of complete degradation of a feather within 24 hours, as feathers are made up of 90% keratin. FIG. A green discoloration on blood agar may appear. The Research/Technology Invention Award 2006 was given to members of the BiotechGenoMik project on B. licheniformis; they invented a system for controlling industrial fermentation, which they named BioChip. It is a rod shaped, endospore bearing bacteria and belong to the family Firmicutes. B. licheniformis is a Gram-positive, rod-shaped, aerobic, endospore-forming organism, which forms colonies of a moderate (2-4 mm) diameter, exceptionally variable in their appearance and often. This is because when under stress, these bacteria (including B. subtilis ) transform into spores and become dormant. FIG. 51.

Irregular form, undulate margin. All rights reserved. Ecologists are looking for signs of association between the plumage feathers and B. licheniformis activity. The B. licheniformis chromosome contains large regions that are colinear with the genomes of B. subtilis and Bacillus halodurans, and approximately 80% of the predicted B. licheniformis coding sequences have B. subtilis orthologs [1]. FIG. Because it is capable of forming endospores that can be easily disseminated, B. licheniformis can be isolated from a variety of places, though it is mainly associated with plant materials. Phenol is a highly persistent environmental pollutant and is toxic to living organisms. The bacterium is also used in the health and catering industries, especially when testing how clean certain work surfaces and materials are. Also, cultures of B. licheniformis are made to retain its protease, which is in turn used in laundry detergent. 47. General characteristics: Gram-positive, long, spore-forming rods with a diameter of < 0.9 m. sparrows)and on the water (i.e. [6][10] There is evidence that red feathers, with psittacofulvin, are more resistant to degradation. B. licheniformis produces many extracellular enzymes, including proteases and lipases which aid in digestion of proteins and fats, respectively. 50. This protease is a desired ingredient in laundry detergent due to its ability to be used in low temperatures, which prevents shrinkage and fading colors. Bacillus thuringiensis cultivated on 5% sheep blood agar. A. and Vicente A. Feathers contain high amounts of non-digestible proteins, but researchers hope that, through fermentation with B. licheniformis, they can use waste feathers to produce cheap and nutritious feather meal to feed livestock. Washington, DC 20036, 2023. As mentioned, Bacillus licheniformis is commonly found on bird feathers; by fermentation with B. licheniformis, the large amounts of non-digestible proteins found in the feathers can turn into a feather meal for livestock. TProbiotic dietary supplements are cheap to manufacture and do not require refrigeration when packaged in the form of spores. Part of colony demonstrating irregular form, lobate margin. In this study, culture conditions were optimized for Bacillus sp. A wide diversity of physiological abilities is exhibited, ranging from psychrophilic to thermophilic, and acidophilic to alkaliphilic; some strains are salt tolerant and some are halophilic.

Streak plate isolation showing colonial morphology of Bacillus cereus on trypticase soy agar (TSA) incubated for 24 hours at 37oC. Ten isolates were characterized by morphological, microscopic, biochemical, molecular, and physiological characteristics. This is desired because it is cheap and nutritious. Unlike other bacilli which are predominately aerobic, B. licheniformis is a facultative anaerobe, which explains it's ability to grow in additional ecological niches and environments. 24.

[18] Natural genetic transformation is a sexual process involving DNA transfer from one bacterium to another through the intervening medium, and the integration of the donor sequence into the recipient genome by homologous recombination. Subtilosin has proven antimicrobial activity against Gram-negative and Gram-positive bacteria as well as anaerobic and aerobic microorganisms. (9). Although B. licheniformis often occurs in high numbers in these foods, it's presence is not usually regulated in contrast to B. cereus, which is credited with most food poisoning incidents by the Bacillus species. Unknown isolate cultivated on trypticase soy agar. Circular form, entire margin. . It is also often found on feathers of ground-dwelling and aquatic species of birds.
