Virgin soybean trypsin inhibitor has 1 NHp-terminal aspartic acid or asparagine residue and no COOH-terminal residues that can be released by carboxypeptidase B. Upon incubation with 1 mole % of trypsin for 24 hours at pH 3.75, virgin inhibitor is converted to a modified inhibitor which has 2 NH2 terminals aspartic acid or asparagine and isoleucine. Approximately 1 mole of arginine is released ...

The present study aims to compare the efficiency of a single extraction and a 3-stage cross-current extraction of PAHs from both lowly contaminated (LC) and highly contaminated (HC) sands using palm kernel and soybean oils (PKO, SO). It is observed that 3-stage cross-current extractions increase the total efficiencies compared to single extractions by 18.7–22.7% and 27.2–30.6% for LC and HC san...

for small cheese-making factories, with no effluent treatment plants, whey can be a serious problem and the landfarming technique represents an alternative for its disposal. however, whey may contain antibiotic residues at the maximum residue limits. therefore, in this work, we evaluated the phytotoxic effect of different concentrations of five antibiotics (enrofloxacin, kanamycin, oxytetracycl...

The cDNA for soybean leghemoglobin a (Lba) was cloned from a root nodule cDNA library and expressed in Escherichia coli. The crystal structure of the ferric acetate complex of recombinant wild-type Lba was determined at a resolution of 2.2 A. Rate constants for O2, CO and NO binding to recombinant Lba are identical with those of native soybean Lba. Rate constants for hemin dissociation and auto...

Soil organic carbon (SOC) turnover plays a pivotal role in achieving C neutrality, promoting retention and increasing soil fertility. Residue biochemistry texture essentially determine SOC distribution (including CO2 mineralization stock soil) farmland. However, less is known about allocation of residue-C with contrasting the fate under two different textures. This study was conducted 61-day ae...

in this study, the main papermaking characteristics of soybean straw (glycine max) as an agricultural residue were investigated. the fiber biometry and chemical composition of soybean straw were determined. the properties of pulps from soda, soda-aq and monoethanolamine (mea) processes were compared. the average fiber length, fiber diameter, lumen diameter, and cell wall thickness were found to...
