Pengukuhan Guru Besar Bu Trisye

Pada Hari Senin Pak Wigf dan Pak Nur berangkat ke Jogja untuk menghadiri pengukuhan Guru besar Prof.Dr.Ir. Endang Sutriwati Rahayu di UGM dalam bidang Mikrobiologi Pangan dengan pidato pengukuhan:Prospek Bakteri Asam Laktat Hasil Rekayasa Genetika Di Bidang Industri Pangan".
Selamat buat Bu Trisye dari kami semua.

Jus Tomat probiotik

Pada hari Jum'at 24 Agustus 2007 Bu Nia dibanti Yuli dn dua siswa SMK yang sedang PKL melakukan penyuluhan dalam rangka pengabdian ipteks di Desa DAU.
penyuluhan mengenai pembuatan jus tmat probiotik agar tomat yang kita minum selain menyegarkan dan kaya vitamin juga mempunyai muatan probiotik yaitu bakteri yang baik bagi saluran pencernaan kita.
semoga masyarakat yang mendapat penyuluhan mampu memanfaatkan sehingga apa yang telah disampaikan tidaklah sia-sia
selamat buat Bu Nia
semoga makin banyak karyanya.

Abstract
The key role of free hydrogen in the digestion of lignocellulose by wood-feeding lower termites and their symbiotic gut microbiota has been conceptually outlined in the past decades but remains to be quantitatively analyzed in situ. Using Reticulitermes santonensis, Zootermopsis nevadensis and Cryptotermes secundus, we determined metabolite fluxes involved in hydrogen turnover and the resulting distribution of H2 in the microliter-sized gut. High-resolution hydrogen microsensor profiles revealed pronounced differences in hydrogen accumulation among the species (from <1 kPa to the saturation level). However, flux measurements indicated that the hydrogen pool was rapidly turned over in all termites, irrespective of the degree of accumulation. Microinjection of radiotracers into intact guts confirmed that reductive acetogenesis from CO2 dominated hydrogen consumption, whereas methanogenesis played only a minor role. Only negligible amounts of H2 were lost by emission, documenting an overall equilibrium between hydrogen production and consumption within the gut. Mathematical modeling revealed that production dominates in the gut lumen and consumption in the gut periphery for R. santonensis and Z. nevadensis, explaining the large accumulation of H2 in these termites, whereas the moderate hydrogen accumulation in C. secundus indicated a more balanced radial distribution of the two processes. Daily hydrogen turnover rates were 9–33 m3 H2 per m3 hindgut volume, corresponding to 22–26% of the respiratory activity of the termites. This makes H2 the central free intermediate during lignocellulose degradation and the termite gut—with its high rates of reductive acetogenesis—the smallest and most efficient natural bioreactor currently known.

Keywords: hydrogen turnover, metabolite fluxes, methanogenesis, quantitative degradation model, reductive acetogenesis, symbiosis
