In the oil industry, mud weight is the density of the drilling fluid and is normally measured in pounds per gallon (lb/gal) (ppg) or pound cubic feet (pcf) . [1] In the field it is measured using a mud scale or mud balance. Mud can weigh up to 22 or 23 ppg. A gallon of water typically weighs 8.33 pounds (or 7.48 ppg).
Pseudomonas infection refers to a disease caused by one of the species of the genus Pseudomonas. P. aeruginosa is a germ found in the environment and it is an opportunistic human pathogen most commonly infecting immunocompromised patients, such as those with cancer , diabetes , cystic fibrosis , [ 1 ] severe burns, AIDS , [ 2 ] or people who ...
Delftia acidovorans is a saprophyte, [6] Gram-negative, non-sporulating, non-denitrifying, non-fermentative rod shaped bacterium. [1] It exists as a single cell or in pairs that are 0.4-0.8 μm wide and 2.5-4.1 μm long. [1] It is motile through polar, or bipolar, tufts of flagella. [1] Tufts can have one to five flagella. [1]
Pseudomonas is a genus of Gram-negative bacteria belonging to the family Pseudomonadaceae in the class Gammaproteobacteria.The 313 members of the genus [2] [3] demonstrate a great deal of metabolic diversity and consequently are able to colonize a wide range of niches. [4]
The type order is the Pseudomonadales, which include the genera Pseudomonas and the nitrogen-fixing Azotobacter, along with many others. Besides being a well-known pathogenic genus, Pseudomonas is also capable of biodegradation of certain materials, like cellulose. [36] The Hydrogenophilalia are thermophilic chemoheterotrophs and autotrophs. [39]
The recall notice from the Consumer Product Safety Commission (CPSC) specifically cites the risk of Pseudomonas aeruginosa and Pseudomonas fluorescens, which are organisms found in soil and water ...
Pseudomonas fluorescens is an unusual cause of disease in humans, and usually affects patients with compromised immune systems (e.g., patients on cancer treatment). From 2004 to 2006, an outbreak of P. fluorescens in the United States involved 80 patients in six states.
Pseudomonas gessardii bacteria are currently used in many industrial processes. Examples of these applications include bioremediation of contaminated industrial sites through degradation of naphthalene and biological reduction of chromium for its removal from the environment, [3] production of lipase active in low pH conditions used in the food, leather and medical industries [5] </ref> and ...
