Abstract

Changes in the Contents of Phytic Acid and Essential Amino Acids of Animal Feed Organic Materials Fermented by Tempe Starter The contents of antinutrients and nutrients are important in the selection of feed ingredients, especially for monogastric animals. The aim of this study is to determine the change in the contents of antinutrient phytic acid and nutrient essential amino acid in selected organic materials. Nine organic ingredients of agro-industrial by-products, namely rice bran, coffee skin, cassava bagasse, corn, coconut dreg, soy bean meal, pollard, corn gluten feed (CGF), and copra meal were fermented in solid state using tempeh starter for 48 hours at 30°C. Dense mycelia overgrowing evenly on the top, bottom, and cross-sliced surfaces was observed on rice bran, maize and copra meal substrates. These 3 selected organic materials were then analysed for the content of phytic acid and essential amino acids. The results showed that the lowest decrease (75.80%) in phytic acid content occurred in maize, namely from 18.49 ± 0.41 mg g-1 (before fermentation) to 4.48 ± 0.19 mg g-1 (after fermentation). The highest increase (59%) of total essential amino acids occurred in copra meal, namely from 38,991.89 ± 447.12 mg kg-1 (before fermentation) to 61,816.56 ± 894.24 mg kg-1 (after fermentation). Kandungan antinutrisi dan nutrisi merupakan hal penting dalam pemilihan bahan pakan, terutama untuk hewan monogastrik. Penelitian ini bertujuan mengetahui perubahan kandungan antinutrisi asam fitat dan nutrisi asam amino esensial pada bahan organik tertentu yang terpilih. Sembilan bahan organik yang merupakan hasil samping agroindustri, yakni dedak padi, kulit kopi, onggok, jagung, ampas kelapa, bungkil kedelai (soy bean meal), dedak gandum (pollard), produk samping jagung corn gluten feed (CGF), dan bungkil kopra difermentasi padat menggunakan ragi tempe selama 48 jam pada suhu 30°C. Miselium yang tumbuh subur, padat, dan merata pada permukaan atas, bawah, dan irisan melintang teramati pada dedak padi, jagung, dan bungkil kopra. Tiga bahan organik terpilih ini kemudian dianalisa kandungan asam fitat dan asam amino esensialnya. Hasil menunjukkan bahwa penurunan terbesar (75,80%) kandungan asam fitat terjadi pada jagung, yakni dari 18,49 ± 0,41 mg g-1 (sebelum fermentasi) menjadi 4,48 ± 0,19 mg g-1 (setelah fermentasi). Peningkatan tertinggi (59%) asam amino esensial total terjadi pada bungkil kopra, yakni dari 38.991,89 ± 447,12 mg kg-1 (sebelum fermentasi) menjadi 61.816,56 ± 894,24 mg kg-1 (setelah fermentasi).

Abstract

Efficient enzymatic production, particularly using Penicillin-G Acylase (PGA), is crucial for synthesizing amoxicillin, a penicillin-type antibiotic. This study optimized PGA immobilization from Bacillus thuringiensis BD1 using Na-alginate to enhance stability and cost-effectiveness. Various Na-alginate concentrations (1%, 1.25%, 1.5%) were tested, with stability assessments at pH 6-9 and temperatures of 30-60 °C, alongside reusability, morphology, and amoxicillin synthesis evaluations. Initial activity was 46.59 U/mg, with optimal immobilization at 1.5% Na-alginate achieving 41.01 U/mg. After four uses, immobilized PGA BD1 retained ±20% activity with optimal conditions at pH 7 and 40 °C. Enhanced amoxicillin synthesis compared to free enzymes highlights its industrial potential. This research demonstrates the feasibility of using immobilized PGA BD1 for scaling up amoxicillin production, offering significant economic and technological benefits.

Abstract

Lipase is applied to hydrolyzethe residual oil or fat in palm oil mill effluent (POME), which serves as a feedstock for biogas production. A bacterial isolate (Bacillus velezensis) exhibiting lipase activity, previously obtained from Malimping, Pandeglang, Banten, Indonesia, underwentsequential treatments of gamma irradiation (1, 2, and 3 kGy), EMS (ethyl methane sulfonate) mutagenesis (0.5% v/v), and NTG (N-methyl N-nitrosoguanidine) (1 mg mL-1). Following each mutation, lipase activities of the mutant colonies were measured and compared to the wild-type strain. The results revealed that all mutated B. velezensiscolonies exhibited lipase activity values (7.78 ± 0.80 –9.05 ± 0.23 U mL-1) that were not significantly different from the wild-type isolate (8.31 ± 0.01 U mL-1), indicating strong bacterial resistance against the mutagenic treatments. The crude lipase preparation effectively hydrolyzed POME, resulting in a reduction of the COD value (from 131,450 ppm to 88,450 ppm) and O&G content (from 41,400 mg L-1to 5,770 mg L-1) within a 72-hour timeframe.

Abstract

Trichoderma spp. are globally considered as the most dominant biofungicide in the market. Reports on Trichoderma spp. efficacy against pathogenic fungi in commercial crops have been numerous, but much less in medicinal plants. This study aimed at testing the potential biofungicidal activity of Trichoderma harzianum in inhibiting the growth of a putatively pathogenic fungus isolated from rodent tuber (Typhonium flagelliforme) plant. The methods consisted of isolation of fungi from the plant’s surface, soil, and polybags. The isolates were then screened for their putative pathogenicity against rodent tuber before being subjected to 16S rRNA molecular identification and in vitro antagonist test using T. harzianum. Result showed that only isolate K4 showed pathogenicity on T. flagelliforme, and was molecularly identified as Lasiodiplodia theobromae, known globally as fungal pathogen attacking various plants. L. theobromae was inhibited by T. harzianum with inhibition index of 23.0 ± 4.3%, which was about twice higher than that of the positive control nystatin 100.000 IU mL (11.1 ± 0.6%). In conclusion, T. harzianum inhibited the growth of L. theobromae in vitro, hence indicating its biofungicidal potential.

Abstract

The sustainability of global palm oil production faces significant threats from a range of diseases and infections affecting palm oil crops. This study presents a comprehensive bibliometric analysis to map the scientific landscape and evolution of research related to palm oil diseases over the past decade. Using data from the Scopus database, 366 relevant documents were analyzed using R and VOSviewer to uncover trends in publication volume, citation impact, prolific authors, country contributions, and keyword co-occurrence networks. The findings reveal a strong research concentration on G. boninense, highlighting its critical role as a persistent pathogen in oil palm plantations. Emerging themes, such as bioactive compound research, comparative biology, and plant–microbiome interactions, reflect the growing interdisciplinary interest in sustainable disease management. This study identified key research gaps and proposed future directions, including molecular breeding, biocontrol strategies, and valorization of bioactive compounds from oil palm by-products. The results offer strategic insights to guide future scientific inquiry and inform sustainable solutions for global palm oil production.
