摘要:
A process for the microbial degradation of waste characterised in that it comprises determining the significant constituent(s) of a waste, providing one or more microorganisms able at least partially to degrade and/or biotransform and/or mineralise each determined constituent of the waste, optionally providing one or more other microorganisms capable of furthering mineralisation of biotransformation or partial degradation product(s), growing one or more mixed cultures of at least some of the microorganisms on a synthetic mixture of at least some of the determined constituents of the waste and utilising the adapted population of microorganisms substantially to mineralise the actual waste is disclosed. The present process is generally applicable, but a particular area of use is in the treatment of waste from acrylonitrile production.

The present invention relates to a recombinant genetically attenuated Bordetella strain expressing a hybrid protein comprising the N-terminal fragment of filamentous haemagglutinin (FHA) and a heterologous epitope or antigenic protein or protein fragment, different from FHA, wherein the gene coding for the native FHA protein is inactivated. The Bordetella strain is preferably a Bordetella pertussis strain, but may also be another Bordetella species, such as Bordetella bronchiseptica, Bordetella parapertussis or Bordetella avium. The invention further provides a life attenuated vaccine for the treatment of a mucosal or systemic infectious disease comprising a Bordetella strain as defined above intended to elicit a immune response against pathogens responsible for systemic or mucosal infections, including of the upper or lower respiratory tract. The present invention also relates to a method for prophylaxis of an infectious disease in a mammal, comprising administering to said mammal an effective amount of a vaccine comprising in a suitable vehicle a recombinant attenuated Bordetella strain expressing a fusion protein comprising the N-terminal fragment of filamentous haemagglutinin (FHA) and a heterologous epitome or antigenic protein or protein fragment, different from FHA, wherein the gene coding for the native FHA protein is inactivated.

Mutant photosynthetic microorganisms having reduced chlorophyll and increased photosynthetic efficiency are provided. The mutants have a locked in high light-acclimated phenotype, in which many of the photosynthetic parameters characteristic of high light acclimated wild type cells are found in the LIHLA mutants when acclimated to low light, such as reduced chlorophyll, reduced NPQ, higher qP, higher Ek, higher P max per unit chlorophyll with little to no reduction in P max per cell, and higher rates of electron transport through photosystem II over a wide range of light intensities. Provided herein are constructs for attenuating or disrupting genes are provided for generating mutants having the LIHLA phenotype. Also provided are methods of culturing LIHLA mutants for the production of biomass or other products.

Processes for producing ethanol comprise saccharifying cellulosic material with a cellulolytic enzyme composition and fermenting the saccharified cellulosic material with a fermenting microorganism to produce ethanol. The fermenting organism is Saccharomyces cerevisiae CIBTS1260 (deposited under Accession No. NRRL Y-50973 at the Agricultural Research Service Culture Collection (NRRL), Illinois 61604 U.S.A.) or a fermenting organism that has properties that the same or about the same as that of Saccharomyces cerevisiae CIBTS1260).
