Laccase induced wheat bran arabinoxylan hydrogels from different wheat cultivars: Structural, physicochemical and rheological characteristics

The influence of different heat treatment levels on the contents of alkylresorcinol and homologues (ARs) was evaluated using wheat bran from two different wheat cultivars. The ARs in the wheat bran were destroyed by all heat treatments investigated in this study (oven treatment, microwave treatment, autoclave treatment, and extrusion treatment). The results showed that the loss rate of ARs by different heat treatment was oven treatment > autoclave treatment > extrusion treatment > microwave treatment, indicating that microwave treatment was more suitable for stabilizing wheat bran than the other three heat treatments. Both temperature and time of heat treatment had effects on the ARs of wheat bran. Higher temperatures and longer times of the treatment resulted in higher loss rates of ARs of wheat bran. The thermal stability of ARs homologues was different between wheat varieties, which may result from the variance of their structure and other components in wheat bran.

Winter Wheat Cultivars

In previous testing, we found that gray snow mold, caused by Typhula ishikariensis or T. incarnata, could be controlled by applying T. phacorrhiza onto turf grass prior to snowfall. To test for phytopathogenicity of this biocontrol agent, the five most disease-suppressive isolates were cultured on mixed grains and applied to 12 turfgrass cultivars and 2 winter wheat cultivars in December 1995 and 1996. After snow melt in April 1996 and 1997, significantly greater winter injury was visible on plots treated with the pathogens compared to T. phacorrhiza-treated plots or untreated plots. Except for one cultivar in 1996, there were no significant differences between T. phacorrhiza-treated plots and untreated plots. Pelletized alginate formulations of T. phacorrhiza containing kaolin clay with various nutritional amendments were tested for viability and efficacy. After 64 weeks of storage, viability remained >85% at -15°C and >70% at 4°C, but <30% at 10°C and 25°C. Significant control of gray snow mold by T. phacorrhiza using small numbers of pellets (20 g/m2) was equivalent to using larger amounts of mixed grain inoculum (200 g/m2) or wheat bran inoculum (100 g/m2) in 2 years of field testing.
