Abstract: Experiments were undertaken to study particle size and its distribution for improvement of peptide production by mixed-culture (Bacillus sublitis, Saccharomyces sp. and Lactococcus lactis) solid-state fermentation (SSF) of soybean meal and the corresponding kinetics. A particle size of 1-1.4mm of soybean meal gave the highest finial peptide yield, and as the proportion of 1-1.4mm/1-2mm in natural soybean meal up to 61.30%/58.58%, the distribution of particle size was also appropriate for peptide production. Logistic model fitted the data most accurately and could be used for growth kinetic profiles during the course of fermentation, and the higher growth rate was calculated for the substrate with optimal particle size distribution. Hence the mechanism could be inferred that appropriate particle size did improve the according rate of microbial growth, thus leading to the higher peptide yield in soybean meal SSF within a limited fermentation time.

Abstract: Climate is the primary determinant of agricultural productivity. Given the fundamental role of agriculture in human welfare, concern has been expressed by federal agencies and others regarding the potential effects of climate change on agricultural productivity. Climate change is expected to influence crop and livestock production, hydrologic balances, input supplies and other components of agricultural systems. However, the nature of these biophysical effects and the human responses to them are complex and uncertain. Technology can be termed as the application of knowledge for practical purposes. In this context, technology allows people to become more efficient or to do things that were not possible before. To benefit from technology, it needs to be successfully linked with country's overall development objectives and applied to solving socio-economic problems. In this paper we propose some practical applications of green technology in agricultural production to regain the loss due to climate change.
