Answer 1

[1] Production of an oxidant and SDS-stable alkaline protease from an alkaophilic Bacillus clausii I-52 by submerged fermentation: Feasibility as a laundry detergent additive by Han-Seung Joo; Chung-Soon Chang [Enzyme and Microbial Technology (v.38, #1-2; pp.176-183)].

An investigation was carried out on enzyme production of an oxidant and SDS-stable alkaline protease secreted by Bacillus clausii I-52 using the submerged fermentation and its application as a detergent additive. Maximum enzyme activity was produced when cells were grown under the submerged fermentation conditions at 37°C for 48h with an aeration rate of 1.5vvm and agitation rate of 700rpm in a medium (pH 10.65) containing (w/v): soybean meal, 20; wheat flour, 10; liquid maltose, 25; K2HPO4, 4; Na2HPO4, 1; MgSO4·7H2O, 0.1; NaCl, 4; FeSO4·7H2O, 0.5; Na2CO3, 6. The alkaline protease produced was found to be highly compatible and stable against not only the commercial detergent components such as α-orephin sulfonate and zeolite but also the commercial detergent preparations. Wash performance analysis using EMPA test fabrics revealed that BCAP exhibited high efficiency for the removal of protein stains in the presence of commercial detergents as well as surfactants. These results suggest that the alkaline protease produced from B. clausii I-52 which showed high stability against detergents has significance for an industrial perspective, especially, detergent additive.

that is all i could find on the word orephin...sounds like some kind of preservative perhaps?
