TL;DR: Rice, a staple food of half the world’s population (Pans 1970), grows and yields better in flooded than in nonflooded soils.
Abstract: Rice, a staple food of half the world’s population (Pans 1970), grows and yields better in flooded than in nonflooded soils.Therefore, rice is generally cultivated under flooded conditions.

TL;DR: Hydrocarbon utilizing organisms isolated from the soil grew rapidly on cycloalkanones, and several cultures, after growth on propane, could oxidize cycloparaffins to the homologous cycloalksanone.
Abstract: All attempts to isolate microoganisms from soil that utilize unsubstituted cycloparaffinic hydrocarbons, e.g. cyclohexane, as sole source of carbon and energy have been unsuccessful. However, cyclohexane was degraded in fertile soil as measured by release of 14C-carbon dioxide on addition of UL-14C-cyclohexane. Hydrocarbon utilizing organisms isolated from the soil grew rapidly on cycloalkanones. Several cultures, after growth on propane, could oxidize cycloparaffins to the homologous cycloalkanone. These results suggest that degradation of cycloalkanes in nature may be via co-metabolism.

TL;DR: In this article, a mixed culture of microorganisms, acclimated to decomposition of crude oil, was used in a series of incubation experiments to determine the sequence of microbial degradation in a Santa Barbara, California, crude oil.
Abstract: A mixed culture of microorganisms, acclimated to decomposition of crude oil, was used in a series of incubation experiments to determine the sequence of microbial degradation in a Santa Barbara, California, crude oil. Microbial degradation of the crude oil is initially characterized by a rapid disappearance of the n-paraffin envelope. This degradation starts with the low molecular weight components and progresses toward the higher molecular weight compounds. The isoprenoids are also progressively reduced simultaneously with the reduction of the paraffins. In addition, the base envelope and fine fingerprint region subsequently undergo degradation and the base envelope becomes progressively skewed toward the higher molecular weight end of the chromatogram. Biodegradation of the Santa Barbara crude oil by a mixed microbial population was initiated simultaneously on all components, but the sequential patterns of decomposition were affected by rate differences.
