The biological activities i. e. antineoplastic activities and antiviral activity of the two novel kinds of interferons: hIFN-λ1 and hIFN-ε were studied and compared. First the fusion expression vector: pcDNA3.1A-hIFN-λ1-His and pcDNA3.1A-hIFN-ε-His by PCR was constructed, then the two kinds of plasmids were transfected into WI-38 (human embryonic lung cells ) with liposome. And cytopathic effect (CPE) suppression test was used to study and compare the antiviral activities of rhIFNλ1-His and rhIFN-ε-His, meanwhile MTT assay was used to detect their antineoplastic activities. It was found that, antiproliferative activity and MxA protein induction shown by rhIFN-λ1-His is more powerful than of rhIFN-ε -His. The antiviral molecular mechanisms of both hIFN-λ1 and hIFN-ε are related to MxA. The foundation for further study on the bioactivities and mechanism of action of hIFN-λ1 and hIFN-ε was established.

Thirty-two bacterial isolates were obtained from wheat rhizosphere in black cotton soils of North Maharashtra region and subsequently tested for in-vitro siderophore production. Wheat isolate SCW1, being a strong siderophore producer, was selected, identified and confirmed as Acinetobacter calcoaceticus. The strain produced catechol type of siderophores during exponential phase which was influenced by iron content of medium. Seed bacterization with siderophoregenic A.calcoaceticus improved plant growth in pot and field studies. Such PGPR activity was attributed to the ability of strain to solubilise phosphates and produce IAA. Siderophore mediated antagonism was observed against common phytopathogens viz., Aspergillus flavus, A. niger, Colletotrichum capsicum and Fusarium oxysporum

The biological!activities i.e. antineoplastic activities and antiviral activity of the two novel kinds of interferons: hIFN-?1 and hIFN-? were studied and compared. First the fusion expression vector: pcDNA3.1A-hIFN-?1-His and pcDNA3.1A-hIFN-?-His by PCR was constructed,then the two kinds of plasmids were transfected into WI-38 (human embryonic lung cells) with liposome. And cytopathic effect (CPE) suppression test was used to study and compare the antiviral activities of rhIFN-?1-His and rhIFN-?-His, meanwhile MTT assay was used to detect their antineoplastic activities.It was found that, antiproliferative activity and MxA protein induction shown by rhIFN-?1-His is more powerful than of rhIFN-?-His.
