Abstract

Currently diagnosis of candidiasis still usingthe traditional standard blood culture method. The traditional method were less sensitive andtime consuming. The purpose of this research were to develope the more sensitive immunosensor based method, and to examine the potency of C. albicans protein extract as bioreceptor to  detect  C. albicans and its biofilm in the blood of candidiasis patients.The research methods include: (1) preparation of  digestive gland liquid of snail (Achatina fulica); (2) extraction of protein from C. albicans  through  enzimatis and mechanic methodsand (3) analyzing the protein extract as bioreseptor through immunodot assay.The research results showed that the snail enzymes has protein content 1.35 mg/ml and  specific activity 1.96 unit/mg. The snail enzyme hydrolyzed  the cell wall of C. albicans  with and without sonication, producedplanktonic extracell protein extract (PEP) and biofilmextracell proteinextract (PEB), planktonic intracell protein extract (PIP), and biofilmintracell protein extract (PIB), withprotein content 1.44; 1.29; 1.29 and 1.21 mg/ml respectively. Thebiofilm intracell protein (BIP) showed antigenic property towardantibody anti-Candida (positive control),giving red spot on imunodot assay. Immunodot assay can distinguishnegative control serum (health man) and positive Candidiasis control by using antigen 1 mg/ml and50ml serum. Keywords: C. albicans, candidiasis, biofilm, immunodot assay

Abstract

This research aimed to explore lipase enzyme from soil through metagenomic approach. The DNA was extracted directly from the topsoil and river sediment by SDS-based lysis method. The soil genomic DNA was sheared into approximately 40-kb fragments The construction of genomic library was carried out by cloning the fragment DNA into  fosmid pCC2FOS vector and host E. coli EPI300-T1R accordance with the protocols of CopyControl™ Fosmid production library kit. Screening of lipase-producing clones was performed based on its lipolytic activity using Luria-Bertani agar plate 12.5 µg/ ml chloramphenicol, 10 µg/ml Rhodamine B and 1 % olive oil as a substrate. The assay plates were incubated at 550 C. The lipolytic activity was identified as an orange around colonies. There were 5 (five) clones of 32 screened-clones that expressed lipolytic activity. The next research will characterize the enzyme and determine the sequence of the enzyme-encoding gene. Keywords: Lipase, soil, metagenomic, fosmid vector, pCC2FOS, E. coli EPI300-T1R

Abstract

Insiden kandidiasis sangat tinggi di dunia yang disebabkan Candida albicans. Agen antifungi telah banyak dikembangkan, namun resistensi terhadap antifungi masih menjadi suatu permasalahan. Resistensi antifungi ini diakibatkan oleh kemampuan C. albicans dalam membentuk biofilm. Terbentuknya biofilm dari infeksi C. albicans diawali oleh proses inflamasi. Proses inflamasi oleh Candida albicans terjadi pada beberapa tahap yang salah satu indikatornya adalah dilepaskannya sitokin proinflamasi (IL-6) dan anti inflamasi (IL-10). Penelitian ini bertujuan untuk mengetahui kadar IL-6 dan IL-10 pada tiap tahapan inflamasi C. albicans pada intestinal pada tikus putih. Penelitian ini menggunakan 32 ekor tikus wistar (Rattus norvegicus) yang dibagi menjadi 2 kelompok, yaitu kelompok kontrol dan perlakuan. Kelompok perlakuan diinokulasi dengan C. albicans. Variabel yang diukur adalah kadar IL-6 dan IL-10 pada hari ke-7, 14, 21, 28 dan 35 setelah inokulasi C. albicans. pengambilan data sebanyak 5 kali dilakukan untuk mewakili tahapan pembentukan biofilm candida. Respon imun pada setiap tahap pembentukan biofilm ditunjukkan dengan kadar sitokin IL-6 dan IL-10 serum darah dengan metode ELISA. Hasil penelitian menunjukkan bahwa kadar IL-6 dan IL-10 pada hari ke-7 dan 14 sebesar 0pg/mL. Pada hari ke 28 telah terjadi proses inflamasi akut  pelepasan IL-6 dan IL-10 dengan kadar tertinggi masing-masing 31,75±9,99pg/mLdan 757,94±576,73pg/mL. Selanjutnya pada hari ke-35, kadar sitokin IL-6 dan IL-10 masing-masing mulai menurun menjadi 28±11,53pg/mL dan 349,5±188,48pg/mL. Respon imun tubuh mulai terjadi pada tahap awal pembentukan biofilm C. albicans intestinal tikus, sehingga kedepannya dapat dikembangkan terapi imunomodulator terhadap kandidiasis sehingga dapat menghambat pembentukan biofilm C. albicans.

Abstract

Recent development in fermentations for bioethanol production were focused three factors, i.e. abundance and cheap substrates,superior yeast fermenting the substrates, and simultaneous saccharification and fermentation (SSF) technology.Nowadays national and world bioethanol production still depend on sugar cane and starchy materials.This research aims to determinate the optimum simultaneous saccharification and fermentation (SSF) conditions to identify the performance of local strain Saccharomyces cerevisiae recombinant [GLO1] in the producing bioethanol from starch.The optimum conditions for SSF process are in a media composition containing glucose 2% (w/v), starch 5% and at aeration rate 50 rpm.At these optimum conditions Saccharomyces cerevisiae recombinant [GLO1] produce 25.36% (v/v) bioethanol at day-20 of the fermentation process design.

Abstract

Natto and Soy Yogurt are fermented food products that are very beneficial for improving health. This community service activity aims to socialize the benefits and make them known to the wider community. However, community service activities during the Covid-19 pandemic cannot be carried out face-to-face and have activities with the community in large numbers. Therefore, this community service activity was carried out through webinar and practical activities. Online seminars was chosen so that the coverage was wider and more people could participate in the pandemic. Face-to-face and community activities are carried out with a limited number of participants, according to health protocols. The level of success, benefit and acceptance of the community from this community service activity is known from the responses of the participants during the activities. Based on the results of the assessment/ response of participants who were present virtually and those present at the location, In general it can be concluded that the PKM activity entitled "socializing the benefits and making natto and soy yogurt through webinars and practices" is going well, but better preparation is still needed.The material presented by the resource person is suitable for the current pandemic conditions, easy to understand, easy to practice and can be developed for home businesses. The Zoom Meeting application can be used as a medium for community service activities in pandemic conditions even though it still cannot reach the wider community.  Keywords: Socialization, natto, soy yogurt, webinar, practical

Abstract

Enzim kitinase banyak digunakan dalam bidang medis, makanan, bioteknologi dan lingkungan. Banyaknya kebutuhan enzim kitinase menuntut penyediannya yang murah dan melimpah dengan teknologi produksi yang sederhana. Penelitian ini bertujuan untuk isolasi mikroba kitinolitik dari cairan fermentasi sampah organik, produksi dan uji aktivitas enzim kitinase serta mengetahui karakteristik dari enzim kitinase. Isolasi mikroba telah dilakukan dengan  metode spread plate. Aktivitas kitinase ditentukan secara kualitatif dengan pengukuran indeks kitinolitik dan secara kuantitatif dengan pengukuran absorbansi menggunakan spektrofotometer Uv-Vis pada panjang gelombang 660 nm berdasarkan banyaknya substrat kitin yang dihidrolisis oleh enzim kitinase. Satu dari beberapa isolat yang didapatkan, yaitu isolat A1 menunjukkan aktivitas kitinolitik tertinggi, yaitu sebesar 1,21. Hasil identifikasi mikrobiologi menunjukkan bahwa isolat A1dinyatakan sebagai Pseudomonas pseudomallei. Bakteri ini mampu menghasilkan kitinase secara optimum pada jam ke 18 waktu fermentasi, dengan penambahan molase 0,5% (b/v) dan 1% kitin (b/v) pada media produksinya. Kitinase yang dihasilkan P.  pseudomallei menunjukkan aktivitas optimum pada suhu 50 °C danpH sebesar 6.
