Butane-utilizing bacteria are used to degrade hydrocarbon pollutants such as trichloroethene (TCE). In-situ or ex-situ techniques may be used to reduce or eliminate hydrocarbon pollutants from liquid, gas and solid sources. In a preferred embodiment, TCE concentrations in various aqueous environments are reduced by contacting a contaminated water source with butane-utilizing bacteria in the presence of oxygen to degrade the TCE by cometabolism or direct metabolism. Suitable butane-utilizing bacteria include Pseudomonas, Variovorax, Nocardia, Chryseobacterium, Comamonas, Acidovorax, Rhodococcus, Aureobacterium, Micrococcus, Aeromonas, Stenotrophomonas, Sphingobacterium, Shewanella, Phyllobacterium, Clavibacter, Alcaligenes, Gordona, Corynebacterium and Cytophaga. The butane-utilizing bacteria have relatively low TCE toxicity in comparison with conventional methane-utilizing bacteria, and demonstrate an improved ability to degrade TCE.

The invention discloses a high-protein straw feed, which comprises crop straw powder, actinomycetes, nocardia, lactobacillus acidophilusis and bacillus subtilis, the weight ratio of the strains is 0.8-1.2:1.6-2.4:0.8-1.2:1.8-1.2, and the weight ratio of the total strain amount to the crop straw powder is 1:1,000-1,200. The preparation method comprises the following steps of: respectively screening, separating, purifying, rejuvenating and culturing various strains, transplanting the strains into an industrial fermentation tank for fermentation, mixing in a ratio, and adsorbing by using an adsorptive support; and inoculating the obtained composite viable bacteria powder into crop straw powder or a mixture of the crop straw powder, staking and fermenting at the temperature of between 60 and 70 DEG C, uniformly turning once every two days, and obtaining the high-protein straw feed after 30 to 35 days. The high-protein straw feed has the advantages of improving protein content, optimizing protein structure, improving the absorption and nutrient conversion rate of the straw feed, and improving the immunity of livestock.

Lovastatin, pravastatin, simvastatin, mevastatin, atorvastatin, and derivatives and analogs thereof are known as HMG-CoA reductase inhibitors and are used as antihypercholesterolemic agents. The majority of them are produced by fermentation using microorganisms of different species identified as species belonging to Aspergillus, Monascus, Nocardia, Amycolatopsis, Mucor or Penicillium genus, Streptomyces, Actinomadura, Micromonospora, some are obtained by treating the fermentation products using the method of chemical synthesis or they are the products of total chemical synthesis. The purity of the active ingredient is an important factor for manufacturing the safe and effective pharmaceutical, especially if the pharmaceutical product must be taken on a longer term basis in the treatment or prevention of high plasma cholesterol. The accumulation of the impurities from the pharmaceuticals of lower purity may cause many side effects during the medical treatment. The present invention relates to a new industrial process for the isolation of HMG-CoA reductase inhibitors using so-called displacement chromatography. Use of the invention enables one to obtain HMG-CoA reductase inhibitors of high purity, with high yields, lower production costs and suitable ecological balance.
