Around 51% of Pseudomonas bacteria found in dairy processing plants are P. fluorescens, with 69% of these isolates possessing proteases, lipases, and lecithinases which contribute to degradation of milk components and subsequent spoilage. [49] Other Pseudomonas species can possess any one of the proteases, lipases, or lecithinases, or none at ...
Phosphorus (P) is one of the major essential macronutrients for plants and is applied to soil in the form of phosphate fertilizers. However, a large portion of soluble inorganic phosphate which is applied to the soil as chemical fertilizer is immobilized rapidly and becomes unavailable to plants. [2]
Pseudomonas syringae—more than any mineral or other organism—is responsible for the surface frost damage in plants [25] exposed to the environment. For plants without antifreeze proteins, frost damage usually occurs between −4 and −12 °C (25 and 10 °F) as the water in plant tissue can remain in a supercooled liquid state.
Pseudomonas azotogensis Voets and Debacker Paenibacillus polymyxa , also known as Bacillus polymyxa , is a Gram-positive bacterium capable of fixing nitrogen . It is found in soil, plant tissues, marine sediments and hot springs . [ 1 ]
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]
Pseudomonas brassicacearum is a Gram-negative soil bacterium that infects the roots of Brassica napus, [1] from which it derives its name. Based on 16S rRNA analysis, P. brassicacearum falls within the P. fluorescens group. [2] It has also been shown to have both pathogenic and plant growth-promoting effects on tomato plants. [3]
The bacterial genus Pseudomonas includes the opportunistic human pathogen P. aeruginosa, plant pathogenic bacteria, plant beneficial bacteria, ubiquitous soil bacteria with bioremediation capabilities and other species that cause spoilage of milk and dairy products.
Pseudomonas citronellolis is a Gram-negative, bacillus bacterium that is used to study the mechanisms of pyruvate carboxylase. [1] It was first isolated from forest soil , under pine trees, in northern Virginia , United States .
