SCREENING AND CHARACTERIZATION OF SOIL FUNGAL ISOLATES FOR INHIBITING THE GROWTH OF Ganoderma boninense
No full textGanoderma boninense, a fungus recognized as a causative agent of basal stem rot and upper stem rot, is primarily found in oil palm plantations (Elaeis guineensis Jack.). This study aimed to identify soil fungal isolates with the greatest potential for inhibiting the pathogenic fungus G. boninense. The research employed curative antagonist testing using in vitro dual culture. Fungal isolates demonstrating the highest inhibition percentages were characterized through macroscopic and microscopic observation, and their hemolysis properties were assessed using blood agar media. Soil fungal isolates FA 3.8 and FA 2.8 exhibited the highest inhibition percentages, reaching 91% and 88%, respectively. Based on morphological characterization at both macroscopic and microscopic levels, FA 3.8 displayed similarities to Trichoderma, while FA 2.8 exhibited similarities to Penicillium. Hemolysis testing results on blood agar media indicated that both isolates exhibited gamma hemolysis or non-hemolysis, as they lacked red blood lysis properties
REVIEW: ANIMAL SERUM REPLACEMENT IN MESENCHYMAL STEM CELLS CULTURE
Get PDFMesenchymal stem cells (MSCs) are being used in clinical applications and must comply with Good Manufacturing Practices (GMP) standards and The National Agency of Drug and Food Control (NA-DFC)) regulations. MSCs cultured using a culture medium and added with several supplements like animal serums. However, animal serums can be a source of virus transmission. Therefore, it is necessary to substitute supplements for the animal serum that are safe to use in cell therapy using MSCs. The paper discusses substituting animal serum MSCs culture. This paper is a literature review through a literature search in scientific journals and research reports that explains the various studies on free serum in the culture of MSCs. It can be concluded that human platelet lysate (hPL), human platelet-rich plasma (hPRP), human serum (hS), human umbilical cord serum/plasma (hUCS/P), or human plasma-derived supplement for cell culture medium (SCC) can be used as substitutes for animal serum in MSCs culture
ANALYSIS OF BBM, LEC, AND SERK EXPRESSIONS IN CALLUS OF SUGARCANE (Saccharum officinarum L.) AT SOMATIC EMBRYOGENESIS DEVELOPMENT STAGES
Get PDFCallus formed in somatic embryogenesis is divided into two types, embryogenic and non-embryogenic callus. Embryogenic callus can be distinguished by the expression of genes as markers related to somatic embryogenesis which are expected to be used as markers to detect callus that has embryogenic capabilities in sugarcane. The aim of this study was to determine the expressions of somatic embryogenesis-related genes in sugarcane. The genes analysis was carried out using somatic embryogenesis callus and using a kit for RNA analysis. Results showed that there were expressions of Baby Boom (BBM), Leafy Cotyledon (LEC), dan Somatic Embryogenesis Receptor Like-Kinase (SERK) gene with specific primer of those three genes, which were collected from embryogenic callus in mass, globular, scutelar, and coleoptilar pre-embryo stages, meanwhile there were no expressions of those genes collected from non-embryogenic callus. Amplification result from PCR product of cDNA using three gene primers detected were in 500 bp for BBM, 400 bp for LEC, and 700 bp for SERK gene

ANALYSIS OF KIDNEY HISTOPATHOLOGY IN SEPSIS MODEL OF MICE (MUS MUSCULUS) WITH PREVENTIVE TREATMENT OF LEAF EXTRACT FROM 'DAUN KENTUT' PLANT (PAEDERIA FOETIDA L.) AGAINST ESCHERICHIA COLI INFECTION
Get PDFSepsis is a critical health concern characterized by organ dysfunction due to uncontrolled host reactions to infections. The prevalence of microorganisms causing sepsis varies, with Gram-positive bacteria and fungal sepsis gaining significance. Sepsis often leads to acute kidney injury (AKI), and its association with sepsis is known as sepsis-associated AKI (SA-AKI). The "Daun Kentut" plant, known for its diverse bioactive compounds, has shown potential in combating inflammation and oxidative stress. In this study, histopathological changes in mouse kidneys induced by Escherichia coli were investigated. Hemorrhage was the primary change observed. Dehydration caused by E. coli infection potentially led to kidney injury through hormonal responses. The plant extract's anti-inflammatory potential, attributed to compounds like saponins and flavonoids, was also explored. The study emphasizes the need for understanding sepsis-related kidney damage and suggests possible preventive strategies using natural compounds
MICROPROPAGATION OF POTATO (Solanum tuberosum L.) cv. GRANOLA IN LIQUID MEDIUM USING AERATION SYSTEM FOR G0 SEED PRODUCTION
Get PDFDisease-free potato seeds of high quality can be obtained via in vitro culture. The use of liquid medium during in vitro cultures might boost the number of plantlets produced, however, the problem of hyperhydricity in plantlets was often encountered. This study aimed to investigate effects of different sucrose concentrations and application of aeration system on micropropagation of potato cv. Granola using liquid medium. Aseptic nodal explants with 3-4 nodes from established in vitro cultures were subjected to MS liquid medium with a factorial treatment of three sucrose concentrations (0, 7.5, 15 g. L-1) and two culture (with and without aeration). The results showed that MS medium with 7.5 g L-1 sucrose was the best medium to produce the highest number of shoots and nodes. Furthermore, it was found that application of aeration system in MS liquid culture decreased plantlet hyperhydricity and increased the number of shoots, number nodes, plantlet height, as well as improved plantlet morphology and vigor. Application of the aeration system in liquid medium produced 200-230 new potato plants per bioreactor in the acclimatization stage and an average of 2773.5 G0 mini tubers
