Growth kinetics of four Trichoderma strains was tested on lignocellulosic by-products in solid state fermentation (SSF). The strains were also analyzed for their survival rate and growth after lyophilization on these carriers. All applied monocomponent and bicomponent media were substrates for the production and preservation of Trichoderma biomass. However, the maximum number of colony forming units (CFU/g dm) was acquired on bicomponent media based on dried grass and beet pulp or grass with corn cobs, when compared to monocomponent media. Although the process of lyophilization reduced the survival rate by 50%-60%, the actual number of viable cells in obtained biopreparations remained relatively high (0.58 × 108 - 1.68 × 108 CFU/g dm). The studied strains in the preserved biopreparations were characterized by a high growth rate, as evaluated in microcultures using the Bioscreen C system.

ABSTRACTThe evaporation of organic by-products released during drying of 1-mm thick silicon tetramethoxide gels was analyzed using gas chromatography. The evaporation kinetics of methanol depended on the drying rate achieved by flowing dry air over the gel. For drying at flow rates less than 50 cm 3/min, exponential kinetics were observed initially with a long time constant (about 100- to 400-min). For drying rates greater than 70 cm3/min, diffusional (t−1/2) kinetics were observed initially. Cracking of the gel during drying was used to indicate the degree of stress. At low drying rates, minor cracking was observed near the edges of the gel. At high flow rates, extensive cracking was observed in samples that exhibited early t−1/2 kinetics. Monitoring the kinetics of drying is essential to optimizing the drying conditions to minimize stress and cracking in gels.

The iron concentrations of chloroplasts (isolated by nonaqueous methods) and of chloroplast lamellae (isolated by aqueous procedures) were determined and used to investigate the kinetics of iron transport across the plasmalemma into the leaf symplast during the recovery of sugar beet plants from iron stress due to iron deprivation. Iron concentrations in chloroplasts isolated by the nonaqueous procedure were greatly reduced during iron stress and recovered to over 200% of control levels within 24 h. Iron concentrations in lamellae from aqueous isolations increased significantly within 24 h of resupply and reached values in excess of control levels in 48–72 h. These results indicate that a substantial quantity of the iron that entered the leaf blade during the first 24–48 h of iron resupply crossed the plasmalemma. The effect appeared to be specific to iron because there was no evidence that manganese, zinc, and copper were transported into chloroplasts and lamellae in enhanced amounts.
