Isolation of antibacterial material-producing bacteria from saline soil

Saline soils are widely spread in Iran. These intact soils are a great source for the isolation of new bacteria with highly functional metabolites in biotechnology. Actinomycete strains were isolated on starch casein agar and ISP2 with different concentrations of sodium chloride (0, 5 and 10%) from treated soil samples. Pure colonies were cultured on a casein glycerol medium. After complete gro...

Bounded Partial-Order Reduction Proof Companion Source Material

Definition 1.6. Preemption-bound persistent sets. A set T ⊆ T of transitions enabled in a state s = final(S) is preemption-bound persistent in s iff for all nonempty sequences α of transitions from s in AG(Pb,c) such that ∀i ∈ dom(α), αi 6∈ T and for all t ∈ T , 1. Pb(S.t) ≤ Pb(S.α1) 2. if Pb(S.t) < Pb(S.α1), then t↔ last(α) and t↔ next(final(S.α), last(α).tid) 3. if Pb(S.t) = Pb(S.α1), then ex...

Synergetic Toxic Effect of an Explosive Material Mixture in Soil

Explosives materials are stable in soil and recalcitrant to biodegradation. Different authors report that TNT (2,4,6-trinitrotoluene), RDX (hexahydro-1,3,5-trinitro-1,3,5-triazine) and HMX (octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine) are toxic, but most investigations have been performed in artificial soil with individual substances. The aim of the presented research was to assess the tox...

The amino-acid composition of the protein material in soil.

Recent work (Kojima, 1947 a; Bremner, 1949) has shown that a considerable fraction of the organic nitrogen of soil is in the form of protein, about onethird of it being liberated as Oc-amino nitrogen by acid or alkaline hydrolysis. No method of separating this protein material from other soil constituents has yet been found and information about its amino-acid composition is scattered and incom...
