“…For example, Xu et al (2014) successfully transformed the waste water from the production of sweet potato starch into a biofertilizer for tea tree polymyxomycetes (Xu et al, 2014); Ogbo and Namfon converted cassava waste and monosodium glutamate by-product into bio-fertilizer respectively (Namfon et al, 2017;Ogbo, 2010). Many reports showed that the low concentration of CSL could promote the germination of soybean seeds and the growth of plants (Zhu et al, 2019) and it can also promote the root of lettuce and repair the soil (Chinta et al, 2014;Salam and Ishaq, 2019).…”

“…As previously reported, the CSL is also applicable to use as a component of growth media, fertilizers and soil conditioners when directly added into soil (Filipović et al, 2001;Obayori et al, 2015). Low concentration of corn steep liquor promotes seed germination, plant growth in soybean and promotes lettuce growth via its antifungal and bio-stimulatory effects (Chinta et al, 2014;Zhu et al, 2019).…”

Corn Steep Liquor (CSL) is wastewater from corn starch industry. The huge amount generation made it as a serious environmental problem. But CSL is nutrient-rich with diverse amino acids and other trace elements. In this study, symbiotic biofertilizer was studied using CSL as main substrate. In this study, 9 industrial strains, which were recognized as high performance species in the biofertilizer industry were collected, including four bacillus, four fungus and one yeast species. Three dominant strains were selected finally, depending on the ability to dissolve phosphorus, ability for protein hydrolysis and cell growth. They were Bacillus subtilis 3301, Bacillus licheniformis and Aspergillus Niger. The results expressed that the highest growth cell count of Bacillus subtilis 3301 reached 3.1×10 9 CFU/mL, the highest protein hydrolysis capacity of Bacillus licheniformis reached 600 mg/L and the highest phosphorus-dissolving capacity of Aspergillus Niger reached 1100 mg/L respectively. Then, symbiotic fermentation of the three strains was carried out both in shake-flask culture and fermentation tank (5 L). Interestingly, series of significant data of symbiotic fermentation were obtained, which were different from individual cultures. Especially, the total growth cell count in the 5 L scale fermenter culture was higher than individual cultures, which proved the mutual promotion effect between different strains. This research would provide a new view to utilize the waste of corn steep liquor as high value-added agricultural products.

“…There were also reports showing that molasses could increase the yield and quality of crops [60,61]. CSL was shown to have beneficial effects on plants [62,63], and supplementation of with exogenous CSL in soil promoted the growth of the root system of soybean [62]. It has been suggested that the organic nitrogen in CSL is converted to nitrate via microbial ammonification and nitrification and directly utilized by plants [64].…”

“…However, it has also been reported that CSL and molasses might have negative effects on plant growth. Zhu et al [62] reported that high concentration of CSL (more than 2%) will inhibit plant growth. In addition, fertilization of molasses singly or in combination with some PGPRs (Bacillus spp.…”

Rhodopseudomonas palustris PS3 is one of the purple phototrophic non-sulfur bacteria (PNSB), which have plant growth-promoting effects on various plants. To expand the scale of PS3 fermentation in a time-and cost-effective fashion, the purpose of this work was to evaluate the use of low-cost materials as culture media and to optimize the culture conditions via response surface methodology. Corn steep liquor (CSL) and molasses were identified as potential materials to replace the nitrogen and carbon sources, respectively, in the conventional growth medium. The optimum culture conditions identified through central composite design were CSL, 39.41 mL/L; molasses, 32.35 g/L; temperature, 37.9˚C; pH, 7.0; and DO 30%. Under the optimized conditions, the biomass yield reached 2.18 ± 0.01 g/ L at 24 hours, which was 7.8-fold higher than that under the original medium (0.28 ± 0.01 g/ L). The correlation between the predicted and experimental values of the model was over 98%, which verified the validity of the response models. Furthermore, we verified the effectiveness of the R. palustris PS3 inoculant grown under the newly developed culture conditions for plant growth promotion. This study provides a potential strategy for improving the fermentation of R. palustris PS3 in low-cost media for large-scale industrial production.

“…Seed storage substances gradually accumulate during seed development and maturation. Protein, one of the seed storage substances, can help a seed to form cellular structures and provide a nitrogen source for normal metabolism and development of seeds, thereby playing a vital role in cellular structure and function [4]. In 1994, Wilkins and Williams first proposed the concept of the proteome, which refers to all proteins expressed in a cell, tissue, or organism [5].…”

Castor bean (Ricinus communis L.), one of the top 10 oilseed crops in the world, has high economic value. Hybridization is the most direct and effective method to breed new varieties with high yield, high oil content, and strong stress resistance. Therefore, prediction of desired traits in castor hybrid offspring is particularly important. In this study, proteomic analysis was performed to identify differentially expressed proteins (DEPs) in seeds between castor hybrid offspring and their female (Lm female line aLmAB2) and male parents (CSR•181). Among the DEPs upregulated in the seeds of hybrid offspring, the majority were related to seed yield and stress resistance, while some were related to oil synthesis and fatty acid synthesis and metabolism in seeds. In other words, the hybrid offspring showed heterosis for seed yield, stress resistance, oil synthesis, and fatty acid synthesis and metabolism when compared with their parents. Further, real-time quantitative polymerase chain reaction assays were performed on 12 genes encoding DEPs involved in oil synthesis, pollen abortion, yield, and stress resistance of seeds. The results showed that the expression levels of the 12 genes were consistent with those of the DEPs.
