Tropical fruits are rich in nutrients and phytochemicals that benefit our health. As source of antioxidant, regular consumption of fruits will be useful in avoiding many degenerative diseases particularly caused by free radicals. The good effects of antioxidants vary from repairing tissue damages in respiratory system, excretory system as well as reproductive system. Ascorbic acid is one potent antioxidant that has been recorded for history. Known as Vitamin C, its concentration in fruits has been a primary consideration for people to choose what kind of fruit they are going to consume. This experiments result exhibited different levels of ascorbic acid in some topical fruits. Average concentration of ascorbic acid from the highest to lowest was obtained in orange, guava, apple, papaya, tamarind and mango with their contents of 96,8; 49,86; 49,57; 48,4 and 41,06 mg/100g, respectively. This result would be a baseline in setting the best fruit combination to obtain maximum effects of antioxidant.

Cigarette smoke is a toxic compound that can interfere with physiological effects and damage the organ systems in the body. The effects of free radicals arising from cigarette smoke can be neutralized by consuming antioxidant compounds. The research aims to look at the protective effects of mixed juice from tropical fruits that grow in Indonesia to the histopathological picture of the kidney of wistar rats exposed to cigarette smoke. There were 35 rats used and divided into 5 treatment groups consisting of K (without treatment), K- (cigarette smoke exposed), P1 (strawberry and guava juice mixed juice 3ml), P2 (strawberry and papaya mixed juice 3ml), P3 (P3 (strawberry and apple mixed juice 3ml). In P1, P2 and P3 before being given a mixture of fruit juice, rats were exposed to cigarette smoke first. The treatment was carried out for 40 days by oral gavage, then on the 41st day the rats were dissected and their kidney organs were taken for observation and histopathological preparations. Histopathology preparations were made by the paraffin method and Haematoxylin Eosin staining. The cell damage data is then analyzed by comparing the kidney cells from the control group with the treatment group and scoring damage followed by the percentage of kidney damage. Data were statistically tested using ANOVA followed by Post Hoc LSD. The results showed that mixed tropical fruit juice could protect kidney cell damage by decreasing the percentage of hydropic degeneration, necrosis and infiltration of inflammatory cells compared with negative controls (P <0.05). There is no significant difference between P1, P2 and P3 in reducing cell damage. The conclusion of the study is that all combinations of tropical fruit juice can protect cell damage caused by free radicals from exposure to cigarette smoke in wistar rats.

Tujuan dari penelitian ini adalah untuk menyelidiki mekanisme penguraian sampah plastik oleh berbagai mikroorganisme, termasuk bakteri, cendawan, dan ulat. Hasil penelitian menunjukkan bahwa mekanisme penguraian plastik melibatkan berbagai strategi biokimia dan enzimatik yang berbeda pada setiap mikroorganisme. Bakteri seperti Ideonella sakaiensis 201-F6 memiliki enzim PETase yang mampu mengurai plastik PET menjadi senyawa monomer yang lebih sederhana. Cendawan seperti Trichoderma viride dan Aspergillus nomius juga memiliki enzim ekstraseluler dan kemampuan untuk mengurai berbagai jenis plastik. Sementara itu, ulat Galleria mellonella dan larva Tenebrio molitor menggunakan mekanisme pencernaan yang melibatkan enzim dan kerjasama dengan bakteri dalam sistem pencernaan mereka. Ulat G. mellonella memakan plastik polyethylene (PE) yang mirip dengan struktur karbon lilin lebah yang menjadi sumber makanan alaminya, sementara larva T. molitor memakan plastik polystyrene (PS) dan menghasilkan enzim serta bakteri dalam sistem pencernaannya untuk menguraikan styrofoam menjadi senyawa organik yang lebih sederhana. Mekanisme penguraian sampah plastik oleh mikroorganisme masih dalam tahap penelitian yang terus berkembang, dan masih banyak hal yang perlu dipahami dengan lebih mendalam. Penelitian lebih lanjut diperlukan untuk mengidentifikasi enzim, jalur metabolic, dan mekanisme detil lainnya yang terlibat dalam penguraian sampah plastik oleh mikroorganisme. Penemuan lebih lanjut tentang mekanisme ini dapat berpotensi menjadi sumber inspirasi untuk pengembangan teknologi bioteknologi yang dapat membantu mengurangi masalah sampah plastik.
