Compared to conventionally used biomass, biochar derived from invasive plants exhibits distinct physicochemical properties and contaminant adsorption capacity. Its utilization provides the dual advantage of managing invasive plants and restoring degraded mine land.

In this study, we explored how different synthetic, short-chain length volatile fatty acids (VFAs) namely acetate, butyrate, and propionate influence the growth, substrate utilization, and PHA production of <em>Halomonas alkalicola</em>, a haloalkaliphilic bacterium isolated from a Kenyan soda lake. Cultures were grown on glucose-rich media supplemented with low levels of VFAs (0.1 %, <em>w</em>/<em>v</em>), and the kinetics of biomass growth, glucose consumption, and PHA biosynthesis modeled using logistic and Luedeking–Piret equations. We found that <em>H. alkalicola</em> showed relatively low tolerance to VFAs. For PHA production, cultures with acetate produced the highest PHA titer (1.472 g/L), followed by butyrate (1.405 g/L) and propionate (1.27 g/L). Acetate and butyrate co-fed cultures showed no significant difference in PHA accumulation while propionate led to a significant decline in production. While VFAs did not enhance overall PHA production, propionate led to significant increase in the 3-hydroxyvalerate (3 HV) fraction of the polymer (18.36 %), compared to 7.15 % in control cultures, suggesting a promising route for tailoring polymer composition toward production of PBHV with high 3 HV contents. Meanwhile, glucose consumption followed similar trends across all treatments, suggesting that VFAs at low concentration had minimal impact on primary metabolism. Our kinetic analysis further revealed that acetate supported the highest biomass accumulation (3.07 g/L), with μₘₐₓ values remaining comparable across treatments (0.11–0.12 h⁻¹).

In order to provide an environmentally benign substitute for synthetic indicators, this study investigates the use of plant wastes (including leaf extracts from <em>Aspilia</em>, <em>fig, pomegranate, lemon,</em> and flower extracts from <em>Ixora coccinea, Mussaenda philippica</em>, and <em>Ruellia tuberosa</em>) as acid-base indicators. The plant extracts were characterized and classified using UV–Vis, FT-IR, FESEM, physical characteristics (density, viscosity, surface tension and refractive index), and qualitative phytochemical screening. The presence of an absorption band in the range of 245 to 247 nm in the UV–Vis spectra corresponds to n → π* transitions. The chromophore groups in the extracts can change electron transitions (n–π*) and rearrange based on pH in the aqueous environment. FT-IR spectra clearly show the hydroxyl and carbonyl groups in the extract moieties, which vary their structure in basic and acidic environments and affect the extract colour. SEM results shows that, the presence of various components in their moiety is the cause of the variance in the morphology of plant extracts. Phytochemical parameters of plant biowaste extracts were screened, classified, and tabulated providing a short library of practical feasibilities tested over a wide acidic-basic interval. In Density Functional Theory (DFT) research, a low energy gap (HOMO-LUMO gap) shows that a molecule can be activated more readily by absorbing a photon of light. The titrimetric analysis shows that the endpoint obtained from the synthetic indicator (phenolphthalein) coincides with the endpoint of extracts with less error % values (1.58–4.54), means that plant extracts were promising as a substitute biomass for acid-base titrations.
