“…Adding of coconut sap to inasua S causes a slight decrease in salt content. Halotolerant bacteria grew well in an environment with a rather high salt content (Ojagh et al 2020). The number of coliform bacteria was not much different during the fermentation process (Figure 1d).…”

Abstract. Mahulette F. 2023. Microbiological and chemical characteristics of porkfish inasua, traditional fish fermented from Maluku, Indonesia. Biodiversitas 25: 1-8. Porkfish inasua consisted of two types, i.e., with and without coconut sap. The research aimed to analyze the microbiological and chemical characteristics of two types of porkfish inasua. The microbiological characteristics are used to determine the role of microbes and product safety whereas the chemical characteristics, including proximate composition, amino acids, and fatty acids contents can determine the nutritional value for consumption. The sample of porkfish inasua was taken from traditional producers in Layeni, Teon, Nila, and Serua (TNS) Islands, Maluku, Indonesia. The microbiological analysis was done using the plate count method. From the measurement, the total number of halotolerant and coliform bacterial in porkfish inasua without sap were 6.2 log cfu/g and 6.1 log cfu/g, respectively. In comparison, the total of Bacillus and related genera in porkfish inasua with sap was 5.9 log cfu/g at the end of fermentation. The fat content of both types of inasua was around 17%. The total amino acids and fatty acids contents of porkfish inasua without sap at the end of fermentation were 15.31 and 57.08%, while porkfish inasua with sap were 15.85 and 63.81%, respectively. The dominant bacteria found in porkfish inasua without sap was Staphylococcus saprophyticus, while porkfish inasua with sap was Bacillus cereus. These two bacteria play a role in fermentation so porkfish inasua was safe for consumption. Generally, chemical characteristics of porkfish inasua with sap were better than those of porkfish inasua without sap, but statistically, it was not significantly different. This research can improve the quality of porkfish inasua as local fermented fish products in Maluku.

“…The use of microalga cultivation as a sustainable wastewater treatment technology also demonstrated promising results. Ojagh et al [132] discovered that Rhodococcus erythropolis PTCC 1767 can remediate synthetic and real PW with COD, TOC, and hydrocarbon (C14-C26) removal efficiencies of 97%, 85%, and 93%, respectively, at 600 mg/L of synthetic PW with a concentration of 60 g/L NaCl. Further, a COD removal efficiency of 52% from PW was a result of adding the remaining cells from the synthetic PW remediation [132].…”

Produced water (PW) is the most significant waste stream generated in the oil and gas industries. The generated PW has the potential to be a useful water source rather than waste. While a variety of technologies can be used for the treatment of PW for reuse, biological-based technologies are an effective and sustainable remediation method. Specifically, microalgae, which are a cost-effective and sustainable process that use nutrients to eliminate organic pollutants from PW during the bioremediation process. In these treatment processes, microalgae grow in PW free of charge, eliminate pollutants, and generate clean water that can be recycled and reused. This helps to reduce CO2 levels in the atmosphere while simultaneously producing biofuels, other useful chemicals, and added-value products. As such, this review focuses on PW generation in the oil and gas industry, PW characteristics, and examines the available technologies that can be used for PW remediation, with specific attention to algal-based technologies. In addition, the various aspects of algae growth and cultivation in PW, the effect of growth conditions, water quality parameters, and the corresponding treatment performance are presented. Lastly, this review emphasizes the bioremediation of PW using algae and highlights how to harvest algae that can be processed to generate biofuels for added-value products as a sustainable approach.

“…Petroleum oil is a valuable strategic resource for which countries compete aggressively. Anthropogenic activities are dependent on oil to meet their energy demand, causing the petrochemical industry to thrive [1,2]. Over the years, large volumes of oily wastewater from petrochemical extraction, refining and processing, storage, and transportation have been discharged into the environment [2,3].…”

Oily wastewater is generated from various sources within the petrochemical industry, including extraction, refining and processing, storage, and transportation. Over the years, large volumes of oily wastewater from this industry have made their way into the environment, negatively affecting the environment, human health, and the economy. The raw waters from the petrochemical industry can differ significantly and have complex features, making them difficult to treat. Membrane bioreactors (MBR) are a promising treatment option for complex wastewater; it is a combined physical and biological treatment. The biological component of the MBR is one of the main contributing factors to its success. It is important to know how to control the parameters within the bioreactor to promote the biodegradation of hydrocarbons to improve the treatment efficiency of the MBR. There have been many reviews on the effects of the biological factors of membrane fouling; however, none have discussed the biodegradation process in an MBR and its impact on effluent quality. This review paper investigates the hydrocarbon biodegradation process in an aerobic MBR system by gathering and analyzing the recent academic literature to determine how oily wastewater characteristics and operational parameters affect this process.
