Processing biomass to obtain hydroxylcarboxylic acids
Biomass (e.g., plant biomass, animal biomass, and municipal waste biomass) is processed to produce useful intermediates and products, such as hydroxy-carboxylic acids and hydroxy-carboxylic acid derivatives. A method includes treating a reduced recalcitrance lignocellulosic or cellulosic material with one or more enzymes and/or organisms (such as lactobacillus, Pediococcus, Rhizopus, Enterococcus) to produce an alpha, beta, gamma and/or delta hydroxycarboxylic acid (such as lactic acid, glycolic acid); and converting the alpha, beta, gamma and/or delta hydroxy-carboxylic acid to the product (such as esters, polymers, and copolymers).

Method for producing aromatic compound
In a cross coupling reaction, in a case where a halogen atom is selected as the leaving group of the raw material compound, a harmful halogen waste forms as a by-product after the reaction, and disposal of the waste liquid is complicated and environmental burden is high. In a carbon-hydrogen activation cross coupling reaction which requires no halogen atom as the leaving group, although no halogen waste forms as a by-product, the reaction substrate is considerably restricted, and the reaction remains a limited molecular construction method. A method for producing an aromatic compound, which comprises subjecting an aromatic nitro compound and a boronic acid compound to a cross coupling reaction in the presence of a metal catalyst.
