The present invention relates to a bacterial process for the production of microbial storage lipids, such as wax esters, triacylclycerides, oils and polyhydroxyalkanoates, from readily available feedstocks derived from biomass. The feedstocks are rich in volatile fatty acids and ammonium, and are generated from biomass via the process of acidogenic fermentation. This allows for the preparation of microbial storage lipids from cheap and readily available biomass sources, such as plant or agricultural waste, or sewage. In particular, the present invention is directed to a process in which the carbon-to-nitrogen ratio of the composition containing volatile fatty acids and ammonium can be effectively controlled so as to optimise the yield of microbial storage lipid production from this process. The present invention also relates to microbial storage lipids that are obtainable by this process, and an apparatus for carrying out the process.

An improved thermoplastic compound and its method of manufacture therefor are disclosed. The thermoplastic compound comprises a semicrystalline polyolefin matrix, selected from polypropylene, high-density polyethylene, or blends thereof, reinforced with a renewable, lignocellulosic nutshell particulate and compatibilized via maleic anhydride grafting.
