In this study, the cultivation and harvesting of Arthrospira platensis biomass were proposed via simple, safe, and efficient techniques for direct consumption. Cultivation of microalgae in a covered macrobubble column under outdoor conditions resulted in significant differences (p < 0.05) with a maximum dry cell weight (Xm) of 0.959 ± 0.046 g/L. No...

MicroRNA (miRNA) is regarded as a prominent genetic regulator, as it can fine‐tune an entire biological pathway by targeting multiple target genes. This characteristic makes miRNAs promising therapeutic tools to reinstate cell functions that are disrupted as a consequence of diseases. Currently, miRNA replacement by miRNA mimics and miRNA inhibitio...

Aseptic technique plays a critical role in determining high volumes of microalgae biomass during the cultivation stage as the presence of a contaminant is one of the limiting factors. This study focuses on developing an energy-efficient method in sterilizing the 2 L microalgae photobioreactor. Initially, the seawater bacterial contaminant was succe...

Arthrospira platensis is a well-known microalgae species that is widely used as the protein and vitamin supplements to aquatic organisms, as well as a complementary dietary ingredient for human. Efficient biomass recovery or harvesting of different algal species is nevertheless a vital bottleneck for a large-scale biorefinery process. Due to its hi...

Spirulina platensis is blue-green microalgae and well known due to its unique nutritional quality that has attracted a great deal of popularity in health products. In this research study, the culture medium uses BG11, SKM and MKM. All these alternative medium recipes are widely used and reported online. However, the suitability of the medium depend...

Oil production from microalgae may be more effective, leaving a smaller environmental footprint and avoiding competition for arable land or biodiversity ecosystems. Present outdoor and open algae cultivation systems and lipid induction methods, on the other hand, need to be significantly improved and are vulnerable to being contaminated by other al...

Purpose of review This review is intended to address the issues of unsafe disposal of antibiotics from various sources to the environment, its incomplete degradation, the resulting antibiotic resistance properties on microorganisms exposed to these antibiotics as well as some currently available techniques to remove both the antibiotic-resistant ba...

Paper de-inking is one of the critical processes in pulp and paper industry as it is ecofriendly and energy saving. This process requires microbial enzymes such as xylanases with ability to withstand harsh bioprocess conditions. Microbulbifer is a halophilic genus with ability to produce hydrolytic enzymes that could be applied in the biotechnologi...

In recent years, photoautotrophic microalgae are widely recognised due to their diverse yet significant natural values, particularly in healthcare, including pharmaceuticals, cosmetics and feedstock industries. One of the most exploited blue-green microalgae, Arthrospira sp. has been addressed as a potent superfood. However, the microalgal massprod...

Purpose of Review Hexavalent chromium, Cr(VI), and trivalent chromium, Cr(III), are two chromium compounds with practical importance due to their high occurrence and solubility in the environment. Current Cr(VI) treatment techniques involve chemical reduction of Cr(VI) to Cr(III), which posed serious threat to workers and environment notably from l...

The emergence of antibiotic resistant bacteria in the aquatic environment has led to an increase in waterborne health risks to an alarming extent. This study attempts to investigate the population of certain antibiotic resistant strains in Peninsular Malaysia. From the samples of 14 rivers from 7 different states, 203 isolates were successfully iso...

microRNAs (miRNAs) are well known as major players in mammalian and plant genetic systems that act by regulating gene expression at the post-transcriptional level. These tiny molecules can regulate target genes (mRNAs) through either cleavage or translational inhibition. Recently, the discovery of plant-derived miRNAs showing cross-kingdom abilitie...

Harvesting and extracting lipids from the microalgal biomass are the most expensive processes in biodiesel production. This study focuses on reducing the lipid extraction cost using ozone-rich microbubbles technique. The lipid extraction of Dunaliella salina slurry with methanol (1:2 v/v) was performed in a 0.2 L bioreactor at room temperature with...
