Abstract

The objective of this research was to study antibacterial and immunostimulatory effects of Trichoderma sp. extract on white shrimp, Litopenaeus vannamei.  First experiment was conducted to evaluate inhibitory effect of Trichoderma sp. againts Vibrio harveyi, a pathogenic bacteria causing vibriosis disease on shrimp.  Second experiment was conducted to evaluate immunostimulatory effect of Trichoderma sp. on shrimp immunity as well as protective effect against V. harveyi. A group of shrimp was injected with a minimum inhibitory concentration obtained at first experiment, and a week after, shrimps was challenged with V. harveyi (prophylactic). Another group was previously challenged with V. harveyi, and subsequently injected with Trichoderma sp. two fold of Minimum Inhibitory Concentration (MIC) a day after (therapeutic). Positive control, that was received only V. harveyi, and negative controls, that was received neither Trichoderma sp. nor V. harveyi were included in this experiment.  Results of first experiment showed that a concentration of 600 ppm was a MIC of Trichoderma sp. to inhibit V. harveyi. While in the second experiment, the groups receiving Trichoderma sp., either prophylactic or therapeutic, showed protective effect against V. harveyi significantly higher than positive control and lower compared with negative control. Total haemocyte count (THC), differential haemocyte count (DHC), phagocytic index and phenoloxydase activity were different among the groups of prophylactic treatment or therapeutic treatment compared to control positive and negative treatments. In conclusion, Trichoderma sp. could be used in prophylactic and therapeutic treatments to combat infection of V. harveyi on L. vannamei. Key words: Trichoderma sp., V. harveyi, immunostimulant   ABSTRAK Penelitian ini bertujuan untuk mempelajari pengaruh antibakterial dan immunostimulasi ekstrak Trichoderma sp. terhadap udang putih, Litopenaeus vannamei.  Percobaan pertama dilakukan untuk mengevaluasi pengaruh penghambatan Trichoderma sp. terhadap Vibrio harveyi, bakteri patogen yang menyebabkan penyakit vibriosis pada udang. Percobaan kedua dilakukan untuk mengevaluasi pengaruh immonustimulasi Trichoderma sp. terhadap imunitas udang serta pengaruh protektif terhadap V. harveyi. Sekelompok udang disuntik dengan konsentrasi hambatan minimum (minimum inhibitory concentration, MIC) yang diperoleh dari hasil percobaan pertama, dan seminggu kemudian udang diuji tantang dengan V. harveyi (profilaksis). Kelompok udang lain diuji tantang dengan V. harveyi sebelumnya untuk kemudian disuntik dengan Trichoderma sp. (therapeutic). Kontrol positif, yang hanya diuji tantang dengan V. harveyi, dan kontrol negatif, yang tidak mendapat baik Trichoderma sp. maupun V. harveyi. Hasil percobaan pertama menunjukkan bahwa 600 ppm merupakan konsentrasi MIC Trichoderma sp. yang memberikan efek penghambatan maksimal terhadap V. harveyi. Sedangkan hasil percobaan kedua, kelompok udang yang mendapatkan Trichoderma sp. baik sebagai profilaksis maupun therapeutic menunjukkan bahwa Trichoderma sp. memberikan efek perlindungan terhadap infeksi V. harveyi secara signifikan lebih tinggi daripada kontrol positif dan lebih rendah daripada kontrol negatif. Total hemocyte count (THC) dan differential hemocyte (DHC), indeks fagositik dan aktivitas fenoloksidase kelompok perlakuan profilaksis atau perlakuan therapeutic berbeda baik dengan kontrol positif maupun negatif. Untuk itu dapat disimpulkan bahwa Trichoderma sp. dapat digunakan dalam tindakan pencegahan dan pengobatan infeksi V. harveyi pada udang putih. Kata kunci: Trichoderma sp., V. harveyi, immunostimulan

Abstract

The use of biocontrol agents have become commonly accepted as a 'natural weapon' in aquaculture, either as an ecological bioremediator for low environmental quality, as well as the health promoter for cultured organisms. Biocontrol agents, which consist of beneficial microorganisms, are commonly applied as biosupplements in feeds. They are potential in replacing the use of antibiotic in inhibiting the pathogenic organisms. Therefore, their application has revealed the potential as an effective strategy to reduce the over use of antibiotics in controlling the pathogenic agents, avoid the spreading the drug resistance, or environmental deterioration of the negative effect by killing useful microorganisms. The development of suitable technology for microbial agents production, viability and stability, is a key area of research for industrial production. Production of biocontrol agents should be based on the microbial criteria, and the ability to withstand stress during processing and storage of products is crucial. This review makes an overview of biocontrol agents selection studies including techniques for isolation/identification, selection, production and its application in order to be accepted as a valuable product in aquaculture. Key words: Biocontrol agents, beneficial microorganisms, aquaculture.   ABSTRAK Pemanfaatan agen biokontrol telah dapat diterima secara luas di dunia akuakultur sebagai senjata alami, baik sebagai bioremediator ekologis untuk memperbaiki kualitas lingkungan yang rendah maupun sebagai promoter/pendukung kesehatan untuk organisme-organisme yang dibudidayakan. Agen-agen biokontrol yang terdiri atas berbagai mikroorganisme yang menguntungkan umumnya diaplikasikan sebagai biosuplemen dalam pakan. Mikroorganisme tersebut potensial dalam menggantikan penggunaan antibiotik dalam proses penghambatan terhadap organisme patogenik. Oleh karena itu, aplikasinya yang sangat potensial dapat berguna sebagai strategi efektif untuk mereduksi penggunaan berlebih dari antibiotik dalam pengendalian agen patogenik, mencegah penyebaran sifat resistensi terhadap obat-obatan, atau mencegah kerusakan lingkungan dari kematian mikroorganisme yang bermanfaat. Pengembangan teknologi yang sesuai untuk produksi, viabilitas dan stabilitas dari agen biokontrol tersebut, merupakan kunci dari penelitian untuk produksi masal pada skala industri. Proses produksi dari agen biokontrol harus berdasar pada kriteria mikrobiologis. Sifat-sifat ketahanannya terhadap stress selama pemrosesan maupun penyimpanan produk adalah penting. Pada makalah ini disajikan teknik-teknik untuk isolasi, identifikasi, produksi dan aplikasi agen biokontrol untuk dapat diterima sebagai produk yang bernilai ekonomis dalam akuakultur. Kata kunci: Agen biokontrol, mikroorganisme yang menguntungkan, akuakultur.
