“…Neem oil cake is given as feed, energy source, protein hydrolysate, biochemical source and used for the production of antibiotics, enzymes and mushroom in industries (Sumitra et al 2007). Neem cake was found to be a biocontrol agent against nematode (Jothi et al 2004), and its toxic effect against Aedes albopictus was studied (Nicoletti et al 2010). Azadirachtin A was extracted from neem seed and studied for its acaricidal activity (Giglioti et al 2011).…”

Animal skin, a proteinaceous material containing about 60-65 % moisture, is an ideal substrate for the growth of microorganisms, if not preserved properly. Conventionally, large quantities of sodium chloride are used for skin preservation. De-salting and soaking carried out during processing of the skin generates serious environmental constraints. In view of this, low-salt skin preservation with de-oiled neem cake is attempted. To ensure the antimicrobial properties of de-oiled neem cake, aqueous and solvent extracts of the cake were studied against bacteria and fungi which were isolated from raw skin. The antimicrobial assay was performed using the well diffusion method for aqueous, methanol and hexane extract of de-oiled neem cake, which showed maximum zone of clearance for aqueous and methanolic extract against the isolated bacteria and fungi, respectively, present in raw skin. The percentage of inhibition study reveals that the methanolic extract showed 100 % inhibition against many organisms and the water extract against some organisms. The raw skin was cured using de-oiled neem cake with reduced amount of salt and left for a period of 21 days. The skins were checked periodically for microbial growth as per the conventional methods. Finally, the low-salt preserved skins were processed into chrome-tanned leathers and their strength properties were compared with leathers which were preserved by the conventional method. The results suggest that de-oiled neem cake along with minimal salt has adequate curing efficiency on raw skin and if this system is implemented, pollution caused due to sodium chloride would be significantly minimized.

“…Neem cake was the most effective and linseed cake or carbofuran the least effective in improving the yield and in reducing reproduction rate of Pratylenchus thornei. The integration of carbofuran with neem cake and castor cake was most effective in increasing plant growth and yield with a decrease in root-lesion nematode population (Jothi et al, 2004). Meyer et al (2006) used the extracts of Plantago lanceolata and P. rugelii against M. incognita and other beneficial and parasitic microbes.…”

To investigate nematicidal activity against the root-lesion nematode, Pratylenchus coffeae, the methanolic extracts were obtained from 5 medicinal plants in Vietnam. Methanol extracts of the 5 samples were screened for nematicidal activity against Pratylenchus coffeae in vitro. Of the plant extracts tested, a 5 mg/ml concentration of Terminalia nigrovenulosa extract showed the highest level (95.0%) of nematicidal activity against Pratylenchus coffeae at 9 h after treatment. The remainder of the plant extracts was followed by Cinnamomum camphora (66.7%), Jasminum suptriplinerve (30.8%), Premna integrifolia (6.7%), and Treptocaulon juventas (5.8%). A 2.0 mg/mlconcentration of T. nigrovenulosa resulted in 13.3, 42.5, 62.5 and 86.7% at 1, 3, 5 and 7 h after treatment, respectively against Pratylenchus coffeae. Concentration of 0.1, 0.5, 1.0 and 2.0 mg/ml of T. nigrovenulosa resulted in 26.7, 71.7, 78.3 and 86.7% effectiveness respectively, at 7 h after treatment. Also, at 3 days after exposure to T. nigrovenulosa, hatch was inhibited by 60.0, 45.8, 17.5 and 5.8% at 0.1, 0.5, 1.0 and 2.0 mg/ml, respectively. Hatch was inhibited by 65.0, 50.8, 21.7 and 6.7% at 0.1, 0.5, 1.0 and 2.0 mg/ml respectively, at 6 days after exposure to T. nigrovenulosa. The mortality rate and hatch inhibition increased with increasing incubation time for crude extract of T. nigrovenulosa. Trong nghiên cứu này, 5 cây thuốc (Cinnamomum camphora, Jasminum suptriplinerve, Premna integrifolia, Terminalia nigrovenulosa, Treptocaulon juventas) đã được sử dụng làm nguyên liệu chiết xuất bằng methanol để thử hoạt tính kháng tuyến trùng Pratylenchus coffeae. Kết quả cho thấy chiết xuất từ cây Terminalia nigrovenulosa biểu hiện hoạt tính kháng tuyến trùng cao nhất (95,0%) sau 9 giờ xử lý với nồng độ 5 mg/ml. Hoạt tính kháng tuyến trùng của các chất chiết xuất được biểu hiện theo thứ tự giảm dần lần lượt là C. camphora (66,7%), J. suptriplinerve (30,8%), P. integrifolia (6,7%) và T. juventas (5,8%). Với nồng độ 2 mg/ml của chất chiết xuất từ T. nigrovenulossa biểu hiện hoạt tính gây chết tuyến trùng Pratylenchuss coffeae là 13,3; 42,5; 62,5 và 86,7% sau 1, 3, 5 và 7 giờ xử lý theo thứ tự. Ở cùng thời điểm sau xử lý 7 giờ, các nồng độ 0,1; 0,5; 1,0 và 2,0 mg/ml chiết xuất của T. nigrovenulossa có hoạt tính gây chết tuyến trùng Pratylenchus coffeae lần lượt là 26,7; 71,7; 78,3 và 86,7%. Bên cạnh đó, chất chiết xuất của T. nigrovenulossa cũng cho thấy tỷ lệ ức chế trứng nở cao. Cụ thể là sau 3 ngày xử lý với chất chiết xuất của T. nigrovenulossa, tỷ lệ ức chế trứng không nở là 60,0; 45,8; 17,5 và 5,8% at 0,1; 0,5; 1,0 và 2,0 mg/ml theo thứ tự. Sau 6 ngày xử lý với chất chiết xuất của T. nigrovenulossa, tỷ lệ ức chế trứng nở là 65,0; 50,8; 21,7 và 6,7% tại nồng độ 0,1; 0,5; 1,0 và 2,0 mg/ml theo thứ tự. Tỷ lệ gây chết và tỷ lệ ức chế của chất chiết xuất phụ thuộc vào cả thời gian và nồng độ xử lý.

A Review on the Challenges for Increased Production of Castor

et al. 2012

View full text Add to dashboard Cite

Castor (Ricinus communis L.) is one of the oldest cultivated crops, but currently it represents only 0.15% of the vegetable oil produced in the world. Castor oil is of continuing importance to the global specialty chemical industry because it is the only commercial source of a hydroxylated fatty acid. Castor also has tremendous future potential as an industrial oilseed crop because of its high seed oil content (more than 480 g kg−1), unique fatty acid composition (900 g kg−1 of ricinoleic acid), potentially high oil yields (1250–2500 L ha−1), and ability to be grown under drought and saline conditions. The scientific literature on castor has been generated by a relatively small global community of researchers over the past century. Much of this work was published in dozens of languages in journals that are not easily accessible to the scientific community. This review was conducted to provide a compilation of the most relevant historic research information and define the tremendous future potential of castor. The article was prepared by a group of 22 scientists from 16 institutions and eight countries. Topics discussed in this review include: (i) germplasm, genetics, breeding, biotic stresses, genome sequencing, and biotechnology; (ii) agronomic production practices, diseases, and abiotic stresses; (iii) management and reduction of toxins for the use of castor meal as both an animal feed and an organic fertilizer; (iv) future industrial uses of castor including renewable fuels; (v) world production, consumption, and prices; and (vi) potential and challenges for increased castor production.
