Using natural aluminosilicate (vermiculite) sorbent for purifying waste water from antibiotics

The problem of wastewater treatment from residual antibiotics is of particular relevance, since these drugs are used in many agricultural sectors. Antibiotics get into water, animal and human bodies, where they can accumulate negatively affecting health. The aim of this article is to study the possibility of using natural aluminosilicate vermiculite sorbent from the Koksharovskoye field (Primorsky Region) for purifying fish processing and fish farming enterprises’ waste water from antibiotics (chloramphenicol, tetracycline, cefazolin, cefuroxime, ceftriaxone, cefepime and and ciprofloxacin) under static and dynamic conditions. The study was carried out on a model wastewater system with injected antibiotics. The purification ability of the model system using the method of spectrophotometric antibiotics detection is analyzed. Under static conditions, the total content of antibiotics varied from 0.25 mg to 1.00 mg per 1 g of sorbent. Under dynamic conditions, the antibiotic content was 0.025 mg per 1 g of sorbent. High values of absorption for all studied antibiotics, except for chloramphenicol, were achieved both in static and dynamic modes. For chloramphenicol, when examined under static conditions, the maximum absorption rate was 45% with the minimum total concentration of antibiotics. With an increase in the load on the sorbent, the degree of absorption decreased to 3%. Thus, vermiculite modified with 7% hydrochloric acid is a promising sorbent for cleaning water bodies from residual antibiotics.

Pemberdayaan ekonomi kelompok nelayan Desa Pangkah Kulon-Gresik dalam memproduksi kerupuk ikan sebagai upaya peningkatan nilai ekonomi ikan sortiran

Pangkah Kulon is one of the villages in Gresik Regency which is located in Ujung Pangkah District, Gresik, East Java. The lack of public knowledge about fish processing makes people required to be more creative in increasing the selling value of fish into processed products. So far, fresh fish caught by fishermen are sold directly to middlemen, while fresh fish that do not pass the sorting is simply thrown away. To increase the economic value of fish into high selling value products, training in the production of fish crackers is carried out. The training was conducted on the socialization of creative preparations, training on the manufacture and creative industry of fish crackers. In this training, participants (fishermen's wives) are trained to operate production equipment, from dough making, milling, to cutting. The knowledge and skills provided can be used as a pioneering effort for the fish cracker creative industry which is a favorite food for the community in general. In addition, it is also a business opportunity that can increase household income.

Prevalensi dan Tingkat Kontaminasi Listeria monocytogenes di Tambak dan Unit Pengolahan Udang Vaname (Litopenaeus vannamei) untuk Pasar Ekspor

Listeria monocytogenes adalah salah satu bakteri patogen yang dapat menyebabkan penyakit bawaan pangan. Penolakan ekspor produk udang beku Indonesia karena kontaminasi L. monocytogenes masih terjadi yang berdampak pada kerugian material bagi pelaku usaha. Tujuan penelitian ini adalah untuk mengetahui prevalensi dan tingkat kontaminasi L. monocytogenes pada produk udang beku untuk pasar ekspor. Sampel yang diambil merupakan udang segar dari tambak dan bahan baku dari bagian penerimaan di Unit Pengolahan Ikan (UPI) serta udang beku sebagai produk akhir UPI, dengan menerapkan sistem ketertelusuran. Lokasi penelitian adalah Sumatra Utara (Medan), DKI Jakarta, Jawa Timur (Surabaya dan Banyuwangi), dan Sulawesi Selatan (Makassar). Identifikasi dan enumerasi L. monocytogenes dilakukan dengan metode MPN-PCR dengan target gen hlyA (~456bp). Prevalensi L. monocytogenes pada udang vaname secara keseluruhan sebesar 6,7% (9/135 sampel), dengan prevalensi di masing-masing titik pengambilan sampel berturut-turut 6,1% di tambak, 9,6% di bahan baku, dan 4% di produk akhir, yang merupakan sampel udang dari batch yang sama. Tingkat kontaminasi L. monocytogenes pada sampel udang vaname berkisar 6,1-1.100 APM/g. Persyaratan L. monocytogenes pada bahan pangan adalah negatif/25g, sehingga sampel udang yang terkontaminasi L. monocytogenes tersebut tidak memenuhi persyaratan sebagai pangan yang aman untuk dikonsumsi berdasarkan regulasi yang berlaku di Indonesia maupun di negara lain. Kontaminasi L. monocytogenes pada udang beku kemungkinan berasal dari tambak ataupun lingkungan pengolahan. Penerapan Good Aquaculture Practices (GAP) di lingkungan tambak udang, serta Hazard Analysis Critical Control Point (HACCP) dan Good Manufacturing Practices (GMP) di UPI perlu dilakukan dengan benar sebagai upaya pengendalian kontaminasi L. monocytogenes. Selain itu, perlu dilakukan kajian lebih lanjut mengenai sumber dan titik kritis kontaminasi L. monocytogenes di sepanjang rantai pengolahan udang beku mulai dari tambak sampai produk akhir.ABSTRACTListeria monocytogenes is pathogenic bacteria that can cause foodborne illness. Rejection of frozen shrimp exports due to L. monocytogenes contamination still occurs and causes economical losses for the industries. The objective of this study was to determine the prevalence and the level of L. monocytogenes contamination in frozen shrimp for export markets. Samples collected were fresh shrimp from shrimp culture and raw material from the receiving point of fish processing plants (UPI), and frozen shrimp as the end product, by implementing a traceability system. Study locations were in North Sumatra (Medan), Special Capital Region of Jakarta, East Java (Surabaya dan Banyuwangi), and South Sulawesi (Makassar). Identification and enumeration of L. monocytogenes were carried out using the MPN-PCR method with the target gene hlyA (~456bp). The prevalence of L. monocytogenes in vanname shrimp was 6.7% (9 out of 135 samples), where 6.1%, 9.6%, and 4% of the prevalence were found in samples from shrimp culture, raw material, and end product, respectively. These samples were from the same batch. The contamination level ranged from 6.1 to 1,100 MPN/g. L. monocytogenes in food should be negative/25g, thus the contaminated samples do not meet requirements as safe for human consumption based on food regulation in Indonesia and other countries. Findings from this study suggested that shrimp culture or fish processing environment are potential sources of L. monocytogenes contamination in frozen shrimp. Therefore, the implementation of Good Aquaculture Practices (GAP) in shrimp culture environment, as well as Hazard Analysis Critical Control Point (HACCP) and Good Manufacturing Practices (GMP) in shrimp processing plant are necessary to control L. monocytogenes contamination. Further studies regarding the sources and critical points of L. monocytogenes contamination throughout the processing of frozen shrimp from shrimp culture to end product are also needed.

MECHANICAL AND PHYSICOCHEMICAL METHODS OF WASTEWATER TREATMENT IN THE FISH PROCESSING INDUSTRY

Currently, the Strategy for the development of the fi shery sector of the Russian Federation for the period up to 2030 has been approved. To implement this strategy, the construction of new and reconstruction of existing enterprises is planned. Wastewater from fi sh processing contains a large amount of scales, remnants of entrails (liver, intestines, ovaries), proteins and lipids. Therefore, when developing a treatment technology, it is necessary to pay increased att ention to mechanical and physicochemical pre-treatment of effl uents. This article summarizes the experience of foreign and domestic research on mechanical and physical-chemical wastewater treatment. Also presented are the results of studies on wastewater treatment of two fi sh processing enterprises. The use of Al2(SO4)3 at a dose of 50 mg/l for Al2O3 gave the best results in a laboratory experiment.

ANALYSIS AND TREATMENT OF WASTE WATER FROM FISH PROCESSING ENTERPRISES

A distinctive feature of waste water of fi sh processing enterprises is the high content of organic substances: COD - 620-3500 mg/L, BOD-220-2860 mg/L. The ratio of BOD:COD=0.68-0.83 in the waste water of fi sh processing enterprises shows a high potential for the use of biological treatment methods. Further study requires the removal of biogenic elements, because, for example, for a fi sh cannery, the ratio of BOD:N:P=100:3.79:1.08 and 100:4.77:0.57. This article presents the experience of design, construction, start-up and adjustment of sewage treatment facilities of a fi sh processing enterprise. For wastewater treatment, the following scheme was developed and manufactured by the ECOLOS company: a receiving well with a basket, a drum grate, a horizontal grease trap, an homogenizer, a reagent pressure fl otation unit, a membrane bioreactor, and ultraviolet disinfection. The quality of waste water at the outlet of the treatment facilities meets the requirements of the Normative- permissible discharge provided by LLC «Russkaya Treska».
