1EOR: Enhanced oil recovery observed in laboratory studies using core type: Berea sandstone core (BS), sand packed column (SP), limestone (L).
2The value was calculated according to a single E. coli cell weight 2.8 x 10-13 g [79].
3Formally B. licheniformis JF-2 [80].
4500 mg·L-1 of dry Bacillus mojavensis yields 34 mg·L-1 lipopeptide [61].
5The yield of biosurfactant per dry cell weight was 0.45 g·g-1 [68,81].
6Engineered with the RhlAB: rhamnosyltransferase complex for synthesis of rhamnose.
7The yield of biosurfactant per dry cell weight was 0.33-0.72 g·g-1 [71]. |
