    Notes: Summary Acetic acid production over 10 days from fresh barley straw was greater than that from fresh wheat straw, but there were only minor consistent differences between different cultivars. The effect depended on the soil type on which the straw had been produced and acid production was greatest with the largest amounts of N fertilizer which had been used. The fertilizer also affected the C:N ratio of the straw

    Notes: Summary Studies using cocultures of a cellulolytic fungus with a capsular organism show that microbial polysaccharides can be synthesized during the degradation of wheat straw. Polysaccharide accounted for up to 1.6% (w/w) of the initial straw weight but the sugar composition and viscosity indicated that a large fraction was low molecular weight material of plant origin. Nevertheless several cocultures produced sufficient microbial polysaccharide effectively to stabilize aggregates of Hamble silt loam. This correlated significantly with increased viscosity and also stabilization of Mount St. Helens volcanic ash. Four cocultures, Sordaria alcina with two strains of Enterobacter cloacae and a Pseudomonas sp. and Trichoderma harzianum with E. cloacae, were significantly more effective than a natural inoculum from straw. Inoculation of straw to produce a “compost” which can increase the stability of poorly structured soils is suggested.
