Well-known Genera not Abundantly Present in Soil References 3. In contrast, zymogenous bacteria are the second group of soil bacteria that require easily oxidizable substrates to grow. Arthrobacter and Nocardia Zymogenous bacterial population in soil is low, as they require an external source of energy. 5. It is widely assumed that low plant species diversity renders agroecosystems vulnerable to harmful soil organisms by reducing overall antagonisms. Soil flora includes bacteria, fungi and algae and tends to be more static. But, zymogenous bacteria need external energy resources or easily oxidizable organic substrates for their growth. Moreover, another significant difference between autochthonous and zymogenous bacteria is that autochthonous bacterial population does not fluctuate while zymogenous bacterial population fluctuates greatly. e.g. The zymogenous flora includes Pseudomonas and Rhodotorula, which respond immediately to glucose, and the autochthonous flora includes Bacillus, coryneform bacteria, Cryptococcus, and Candida, which show only a limited or slow response to glucose. Autochthonous bacterial population in the soil is high and uniform.

Xarrin Sindhu Mphil(Env. e.g. A good perceptive view of microbial systems in the soil is an important prerequisite to understanding the impact of soil dynamics on biological control. Zymogenous bacteria are a group of soil bacteria that require easily oxidizable substrates for their growth. nous adj. Generally, their number in the soil does not fluctuate. They can grow in soil which contains a limited source of energy. The key difference between autochthonous and zymogenous bacteria is that autochthonous bacteria are native or indigenous microorganisms that grow and metabolize under scarce nutritional resources while zymogenous bacteria are a group of bacteria that require easily oxidizable organic materials for growth. They are uniformly spread in soil. Methylomonas, Nitrosomonas, Pseudomonas aeruginosa, Nitrospira and Nitrobacter species are several zymogenous bacteria. Application of neem products like neem leaf and neem cake to wetland soil did not have any adverse effect on the population of heterotrophic microflora; nitrifying bacteria, on the other hand, decreased significantly due to addition of neem cake and fresh and dried neem leaf with urea. yang dimaksud dengan zymogenous flora adalah kata yang memiliki artinya, silahkan ke tabel.
