Microbial Lipid Production by Co‐Fermentation with Mortierella alpina Obtained by Ion Beam Implantation
Authors: Peng W. , Lamei Z. , Zhiming Z. , Li W. , Hui W. , Chengling Y. , Guohong G. 
Published: February 2011

AbstractCo‐fermentation of lignocellulose‐based carbohydrates is a potential approach to improve the economics of microbial lipid production. To obtain an industrial strain that metabolizes glucose and xylose with a higher microbial lipid production, the strain Mortierella alpina was mutated by low‐energy ion beam implantation. After nitrogen ion beam implantation, a mutant strain, M. alpina I502‐8 (MAI502‐8), was obtained. MAI502‐8 was an efficient producer of microbial lipid from glucose and xylose (5:3 wt/wt). Moreover, the co‐fermentation conditions were also optimized. Under optimal conditions, the maximum yield of biomass and microbial lipid reached 27.4 and 10.05 g L–1, respectively, which were 2.38‐fold and 1.84‐fold those in the initial media. Of the mixed sugar, 84.33 % was used up during co‐fermentation.
Formation of the Iron–Oxo Hydroxylating Species in the Catalytic Cycle of Aromatic Amino Acid Hydroxylases
Authors: Olsson Elaine , Martinez Aurora , Teigen Knut , Jensen Vidar R. 
Published: February 2011

AbstractThe first part of the catalytic cycle of the pterin‐dependent, dioxygen‐using nonheme‐iron aromatic amino acid hydroxylases, leading to the FeIVO hydroxylating intermediate, has been investigated by means of density functional theory. The starting structure in the present investigation is the water‐free FeO2 complex cluster model that represents the catalytically competent form of the enzymes. A model for this structure was obtained in a previous study of water‐ligand dissociation from the hexacoordinate model complex of the X‐ray crystal structure of the catalytic domain of phenylalanine hydroxylase in complex with the cofactor (6R)‐L‐erythro‐5,6,7,8‐tetrahydrobiopterin (BH4) (PAH‐FeII‐BH4). The OO bond rupture and two‐electron oxidation of the cofactor are found to take place via a Fe‐O‐O‐BH4 bridge structure that is formed in consecutive radical reactions involving a superoxide ion, O2−. The overall effective free‐energy barrier to formation of the FeIVO species is calculated to be 13.9 kcal mol−1, less than 2 kcal mol−1 lower than that derived from experiment. The rate‐limiting step is associated with a one‐electron transfer from the cofactor to dioxygen, whereas the spin inversion needed to arrive at the quintet state in which the OO bond cleavage is finalized, essentially proceeds without activation.
Nickel‐Catalyzed Cross‐Coupling of Phenols and Arylboronic Acids Through an In Situ Phenol Activation Mediated by PyBroP

Published: February 2011

AbstractA new method for the Suzuki–Miyaura cross‐coupling of phenols and arylboronic acids through in situ phenol activation mediated by PyBroP is presented. The reaction proceeds efficiently by using cost‐effective, markedly stable [NiCl2(dppp)] (dppp=1,3‐bis(diphenylphosphino)propane) as the catalyst in only 5 mol % loading, as well as in the absence of extra ligands. The method exhibits broad applicability and high efficiency towards a wide range of both phenols and boronic acids, including activated, nonactivated, deactivated, and heteroaromatic coupling partners. In addition, various functional groups, such as ether, amino, cyano, ester, and ketone groups, are compatible with this transformation. Notably, arylboronic acids containing an unprotected NH2 group and 2‐heterocyclic boronic acids, which are generally problematic for coupling under conventional conditions, are also viable substrates, although moderate yields were obtained for sterically hindered substrates. Consequently, the in situ cross‐coupling methodology coupled with the use of an inexpensive and stable nickel catalyst provides a rapid and efficient pathway for the assembly of biaryls and heterobiaryls with structural diversity from readily available phenol compounds.
