The invention encompasses the use of a lipolytic enzyme obtainable from one of the following genera: Streptomyces, Corynebacterium and Thermobifida in various methods and uses, wherein said lipolytic enzyme is capable of hydrolysing a glycolipid or a phospholipid or transferring an acyl group from a glycolipid or phospholipids to an acyl acceptor. Preferably, the lipolytic enzyme for use in these methods and uses comprises an amino acid sequence as shown in any one of SEQ ID NOs: 4, 5, 7, 8, 12, 14 or 16 or an amino acid sequence having at least 70% identity therewith or comprises a nucleotide sequence shown as SEQ ID NO: 3, 6, 9, 13, 15 or 17 or a nucleotide sequence which has at least 70% identity therewith. The present invention also relates to a lipolytic enzyme capable of hydrolysing at least a galactolipid or capable of transferring an acyl group from a galactolipid to one or more acyl acceptor substrates, wherein the enzyme is obtainable from Streptomyces species and includes a lipolytic enzyme comprising an amino acid sequence as shown in SEQ ID NO: 4 or an amino acid sequence which has at least 60% identity thereto. The enzyme may be encoded by a nucleic acid selected from the group consisting of: a) a nucleic acid comprising a nucleotide sequence show in SEQ ID NO: 3; b) a nucleic acid which is related to the nucleotide sequence of SEQ ID NO: 3 by the degeneration of the genetic code; and c) a nucleic acid comprising a nucleotide sequence which has at least 70% identity with the nucleotide sequence shown in SEQ ID NO: 3.

The invention relates to a compound microbial bacterial preparation for efficiently degrading feces and a preparation method and application of the compound microbial bacterial preparation. The compound microbial bacterial preparation is prepared from bacillus subtilis, bacillus cereus, bacillus megaterium, geobacillus stearothermophilus, aspergillus oryzae, trichoderma longibrachiatum, sporotrichum thermophile and streptomycesmicroflavus through solid fermentation. The compound microbial bacterial preparation can shorten the fermentation time of feces, and effectively kill larva, eggs and pathogens in the feces, and further improves the content of organic matters, total nitrogen, total phosphorus, and total potassium in the fermented materials.

The invention discloses a Streptomyces sp. strain and the application thereof. The strain provided by the invention is Streptomyces sp. YL04 CGMCC No.2884.

The invention has significant scientific meaning and application value in enriching strain resources for biocontrol of our country and provides effective measures for achieving high-output and high-quality modern agriculture. The invention meets the national standards of agricultural goods production safety and the need of constructing a non-polluted, green and organic agricultural production base and has certain economic and social benefits.

The invention discloses a biocontrol actinomycete strain for preventing and controlling tobacco bacterial wilt and application method thereof and belongs to the technical field of micro-organisms. The strain is streptomyces K4, is collected in China General Microbiological Culture Collection Center on March 24, 2014 and has the collection number of CGMCC No. 8949. The strain generates active substances to inhibit the growth of tobacco bacterial wilt and exhibits better prevention and control effects on the tobacco bacterial wilt. The biocontrol actinomycete strain is used for preparing a biocontrol microbial agent and the biocontrol microbial agent can be applied together with rooting water when tobacco seedlings are transplanted; or the biocontrol microbial agent is irrigated into the roots at 4-5 days after the tobacco seedlings are transplanted. The microbial agent can be applied as a bacterial fertilizer prepared by mixing the microbial agent and an organic fertilizer. The strain K4 is obtained from tobacco field rhizosphere soil and is ecologically and harmoniously compatible with soil so that the strain K4 has good application prospects in the biological control of tobacco bacterial wilt.

The invention discloses Streptomyces rochei 42561 which is preserved in the general microorganism center of the China Committee for Culture Collection of Microorganisms (CCCCM), with the preservation number of CGMCC (China General Microbiological Culture Collection Center) NO.6556. The bacteriostatic and prophylactic actions of the biocontrol bacterium 42561 are comprehensively tested according to a cup-plate method, a mycelial growth rate inhibition method, a spore germination inhibition method, greenhouse pot culture and field tests; and the testing results show that the strain has a remarkable prevention effect on cotton blight and cotton greensickness, can be used as an effective biological pesticide preparation agent and has excellent application and development prospects.
