A shroud for an aircraft configured to at least partially surround a noise source including a propeller. The shroud includes an outer layer and two or more sound absorbing materials located inside the shroud. The outer layer is configured to transmit noise from the noise source into the inside of the shroud and/or includes a recess located and sized to partially surround at least a part of a tip of at least one blade.

Shroud

A biologically pure isolate of a selected bacterium derived fromis described which has improved efficiency in the production of ethanol by anaerobic fermentation of substrates comprising carbon monoxide. The bacterium can produce ethanol and acetate at an ethanol to acetate ratio of at least 1.0 and has a productivity of at least 1.2 g of ethanol/l of fermentation broth per day. The bacterium is also characterized in that it has substantially no ability to sporulate.

Bacteria and methods of use thereof

The invention relates to biological processes for producing one or more desired products, including alcohols such as ethanol and butanol. The processes comprise carrying out first and second fermentations of substrates in first and second bioreactors, wherein each fermentation produces one or more desired products and/or one or more by-products that can be utilized in the other fermentation. A product and/or by-product of the first fermentation is introduced to the second bioreactor during the fermentation, and a product and/or by-product of the second fermentation is introduced to the first bioreactor during the fermentation.

Alcohol production process

A novel class of bacteria is described which has improved efficiency in the production of thanol by anaerobic fermentation of substrates containing carbon monoxide.

The invention relates to the production of alcohols by microbial fermentation, particularly to production of alcohols by microbial fermentation of substrates comprising CO. It more particularly relates to processes for the production of alcohols from their corresponding acids in the presence of a substrate comprising CO. In particular embodiments, a fermentation reaction producing acid(s) and optionally alcohol(s) is perturbed such that at least a portion one or more of acid(s) is converted to alcohol.

Microbial alcohol production process

The present invention relates to methods for increasing the efficiency of anaerobic fermentation processes (1) that produce acetate as a by-product in addition to a desired product, and (2) that can utilize hydrogen and/or carbon dioxide in the fermentation. The method comprises the steps of converting acetate produced by the fermentation process into hydrogen gas and carbon dioxide gas, and utilizing hydrogen gas and/or carbon dioxide gas obtained from the acetate conversion in the anaerobic fermentation process. In particular aspects, the invention relates to processes of producing alcohols, particularly ethanol.
