Abstract

The production of single cell protein (SCP) is one of the cheap protein sources for use in aquaculture. In this study, Claveromycice frajilice and Fusarium oxysporum were used to produce SCP using Kilka stick water as the source of medium. Adaptation of C. frajilice and F. oxysporum to pure stick water was performed by increasing the concentration of stick water in distilled water. Treatments included 50% and 100% stick water, and a group without stick water as control. The pattern of the yeast and fungus growth was studied by spectrophotometry at 600 nm. The final product was analyzed for values of dry materials, amino acids profiles, total protein, moisture and ash. The results showed protein production by C. frajilice in 50% and 100% stick water was 55.35% and 57.47%, respectively, compared to 54.65% in control group (P>0.05). Protein production using F. oxysporum was 53.17% and 54.39±0.45%in 50% and 100% stick water, respectively compared to 49.71% in control group (P>0.05). The results showed that amino acids composition in produced SCP was comparable with the suggested profiles of requirement by FAO/WHO and NRC. Based on to the obtained results, application of pure Kilka stick water is suitable for production of C. frajilice as the source of SCP.

研究文章：弗氏灭活菌和尖孢镰刀菌在Kilka棒水中单细胞生产

单细胞蛋白(SCP)的生产是用于水产养殖的廉价蛋白质来源之一。本研究以脆弱克拉维菌和尖孢镰刀菌为原料，以Kilka棒水为培养基源，制备SCP。通过提高蒸馏水中木棒水的浓度，实现了脆弱菌和尖孢菌对纯木棒水的适应。采用50%和100%棍水处理，无棍水处理为对照组。用分光光度法研究了酵母和真菌在600 nm下的生长规律。对最终产品的干物质、氨基酸谱、总蛋白质、水分和灰分进行了分析。结果表明:50%和100%粘结水条件下，弱冰酵母蛋白质产量分别为55.35%和57.47%，高于对照组的54.65% (P < 0.05);50%和100%粘水条件下，尖孢镰刀菌蛋白质产量分别为53.17%和54.39±0.45%，而对照组为49.71% (P < 0.05)。结果表明，所产SCP的氨基酸组成与FAO/WHO和NRC建议的需要量相当。根据所得结果，采用纯Kilka棒水作为SCP的来源，适合于软冰的生产。
