The aim of present investigation was to examine the potential of indigenous bacteria, isolated from textile effluent contaminated soil samples for decolorization of textile dye (Direct blue 53) and textile effluent. Bacterial isolates were evaluated for decolorization in mineral medium amended with Direct blue dye at varying concentration of 10-200 mgL-1. Different incubation parameters such as temperature, pH and aeration were optimized to enhance decolorization rate. The potent bacterial isolates Pseudochrobactrum kiredjianiae YPR 5, Brevundimonas diminuta YPR 25 and Alcaligenes faecalis YPR 36 showed significant decolorization potential after 72 of incubation. Maximum decolourization of Direct blue 53 (200 mgL-1) shown by Alcaligenes faecalis YPR 36 (74.8%) followed by Brevundimonas diminuta YPR 25 (66.9%) at optimum pH (7.0) and temperature (35 °C) under static condition within 72 h of incubation. Pseudochrobactrum kiredjianiae YPR 5 gave dye decolourization (100 mgL-1) of 61.4% at pH (7.0) and temperature (35 °C) under static condition within 72 h of incubation. Alcaligenes faecalis YPR 36 decolourizes (48.5%) textile effluent (25%) after 120 h of incubation. Phytotoxicity studies on seeds of Cicer arietinum, Vigna radiata and Vigna mungo found that treated textile effluent showed less inhibitory effect on seed germination as compare to untreated textile effluent. In conclusion, the results showed that the bacterial isolates have ability to decolourize the textile dye Direct blue 53 dye and textile effluent under the optimized conditions.
Experiments were conducted to evaluate the performance of eight polyhouse cucumber inbreds for earliness, yield and disease tolerance against downy mildew at Bihar Agricultural University, Sabour, Bhagalpur during Spring and Kharif seasons 2018 in saw-toothed naturally ventilated polyhouse. The data were recorded for thirteen quantitative characters viz., days to first female flower anthesis, node number to first female flower, days to first fruit harvest, fruits per plant, flesh thickness (cm), fruit length (cm), fruit diameter (cm), average fruit weight (g), vine length (cm), crop duration, yield per plant (g), TSS and PDI (%) for downy mildew. The study reported that the genotypes BRPCU-1, BRPCU-2 and BRPCU-3 were identified as best genotypes in respect to earliness in pooled over seasons. While, BRPCU-1 and BRPCU-2 showed resistance and moderately resistance, respectively in terms of PDI (%) for downy mildew. For yield and its contributing traits, the inbred lines BRPCU-3 and BRPCU-5 showed better performance in pooled over season.
Multiplication of a plant using in vitro culture technique greatly influences with the composition of culture media. Identification of suitable culture media is pre-requisite for getting maximum pace of micropropagation. Therefore, the efficacies of six different culture media for multiplication of Aloe vera were evaluated under in vitro condition using lateral shoot explant. An optimum level of BAP and IBA were used for shoot proliferation and root induction, respectively. Significant variation was obtained in all media types for all the characters studied. MS medium was found best for direct shoot proliferation as it induced highest number of shoot (6.30±0.23) per explant with longest shoot length (3.17±0.09 cm). The order of efficacy of different media for shoot proliferation was as MS medium > Woody plant medium > Nitsch and Nitsch medium > Whites medium > Knudson Solution-C > Schenk and Hildebrandt medium. For root induction, Woody plant medium revealed maximum number of roots (6.10±0.23) per explant, followed by MS medium. The effectiveness of different media for root proliferation were as Woody plant medium > MS medium > Nitsch and Nitsch medium > Whites medium > Knudson Solution-C > Schenk and Hildebrandt medium. Highest survival rate (85 %) during hardening and acclimatization was also obtained in Woody plant medium mediated rootlets. The identified culture media can be recommended for high frequency large scale multiplication of Aloe vera.
The quality of vegetables is determined by many factors such as texture, flavor, chromaticity, and health-beneficial metabolites. Chinese cabbage is one of the most commonly consumed vegetables in Western and Asian and countries including Korea. Change in firmness of Chinese cabbage leaf tissues has not been comprehensively studied, although it serves as an important quality indicator of this product. The objective of this study was to characterize textural parameters of Chinese cabbage and to compare them in different cultivars and cultivation practices (soil fertigation or hydroponics). Soluble sugar content, leaf thickness, and chromaticity were higher in plants grown via hydroponics than in those grown via fertigation. Meanwhile, firmness and dry mass of midrib tissues showed an opposite trend in all tested cultivars. Additionally, starch contents and cell wall compounds (i.e., polyuronides and non-cellulosic neutral sugars) of midrib tissues were detected higher in plants grown via fertigation than in those grown via hydroponics. Moreover, the amounts of starch, cell wall compounds, and neutral sugars showed a positive correlation with the firmness of Chinese cabbage leaf tissues. Taken together, these data provide an informative insight for improving cultivation practices, particularly hydroponics of Chinese cabbage plants.
Combination mode and working parameters of the cleaning fans of the combine harvester have an important influence on the loss rate and the cleaning rate for different cleaning materials. In this paper, when centrifugal fan was acting alone and cross-flow fan acting alone, the airflow velocity at the indoor space point of cleaning room were measured on a cleaning device. The isokinetic distribution diagrams in different sections were drawn and the characteristics were analyzed. The results showed that under the action of the centrifugal fan, the airflow speed increases as the speed increases. The influence of the cross-flow fan on the screen surface is mainly concentrated on the screen tail, the increase in the speed of the cross-flow fan will expand the scope of influence.
