| Abstract: | Budidaya menghasilkan sejumlah besar limbah, terdiri dari metabolisme oleh-produk, makanan sisa, materi feses dan residu dari masukan profilaksis dan terapeutik, mengarah pada penurunan kualitas air dan wabah penyakit. Bioremediasi, aplikasi mikroba / enzim untuk tambak, adalah metode yang sedang digunakan untuk meningkatkan kualitas air dan menjaga kesehatan dan stabilitas sistem akuakultur. Bioremediasi melibatkan mineralisasi bahan organik menjadi karbon dioksida, memaksimalkan produktivitas primer yang merangsang produksi udang, nitrifikasi dan denitrifikasi untuk (1) menghilangkan kelebihan nitrogen dari tambak dan (2) mempertahankan beragam dan stabil masyarakat kolam dimana patogen dikeluarkan dari sistem dan spesies diinginkan mendapatkan didirikan. Selain dari bahan organik merendahkan (detritivorous) bakteri heterotrofik, nitrifikasi, bakteri denitrifikasi dan fotosintesis umumnya digunakan dalam bioremediasi. |

| Abstract: | The thesis comprises a set of experiments mainly focused on the improvement of L-glutamic acid fennentation. Much attention has been given to use of locally available raw materials, culturing the organism on inert solid substrates and also immobilization of the bacterial cells from the view point of long term utilization of biocatalyst and continuous operation of the stabilized system. Studies were also carried out for the down stream processing for the extraction and purification of L-glutamic acid. An attempt was made to study the morphological features of the microorganism including the cell premeability. In relation with the accumulation of glutamic acid within the cells an approach was made to study the behaviour of the Brevibacterium cells when they are exposed to hyper osmotic environment. Attempts were also made to study the requirement of iron and production of siderophores by this microbial strain. The search for a suitable nitrogen source for glutamate fermentation ended with a promising result that they got a potent urease activity and it can be utilized for many biotransfonnation studies. The entire thesis is presented in three sections, viz. introductory section, experimental section and the concluding section |
