A proteinic biomass preparation comprising a non-native organism of the Clostridia class, which organism expresses (i) a modified aspartate kinase; (ii) a modified homoserine dehydrogenase; (iii) a modified homoserine kinase; (iv) a modified anthranilate synthase; (v) a functional lycopene pathway and the genes crtY, crtW, and crtZ; and/or (vi) a functional oleic acid pathway and the four gene operon (pfaABCD). Methods of producing proteinic biomass preparations are also described.

A recombinant microorganism of the genus Komagataeibacter having enhanced cellulose productivity and yield, a method of producing cellulose using the recombinant microorganism, and a method of producing the recombinant microorganism are provided.

Methods and means are provided to increase the seed oil content of Brassica plants by preventing feedback inhibition by phosphoenolpyruvate (PEP) of a pyrophosphate-dependent phosphofructokinase (PPi-PFK) present in cells of seeds or embryos of these plants, in various manners, including by providing feedback insensitive or less sensitive PPi-PFK.
