Abstract: A powered air purifying respirator (PARR) has a yoke and a pump. The yoke defines an air inlet and an air outlet fluidly connected via an air flow passage. The pump is disposed within an interior of the yoke and is configured to pump air from the air inlet to the air outlet via the air flow passage. The yoke is shaped to fit around the user's neck and be supported by the user's shoulders. A hood for a PARR has a head portion configured to receive a user's head, and a one-way exhaust valve configured to vent air from an internal environment of the hood to an environment external to the hood. The hood is configured to receive a yoke of the PARR.

Abstract: The invention relates to a strip holder consisting of a housing with a front side and a back side, the housing comprising at least one strip receiving channel, at least one fluid receiving channel, at least one fluid reservoir, and optionally at least one ventilation channel. The invention also relates to a use of the strip holder, a method as well as to a kit comprising the strip holder.

Abstract: The present invention relates to the isolation of carotenoids and in particular the xanthophyll zeaxanthin (zeaxanthin-?,?-Carotene-3,3?-diol) and optionally other carotenoids such as lycopene, ?,?-carotene, 3?-hydroxyechinenone ?-cryptoxanthin and the colourless carotenoids, phytoene and phytofluene from a marine bacterium belonging to the genus Algibacter which is capable of producing the aforementioned compounds. The present invention also provides a strain of Algibacter which is capable of producing significant levels of carotenoids, especially zeaxanthin at high purity, as well as methods of using the Algibacter strain and uses of the carotenoids produced.
