Article Synopsis
  • Three newly identified Cladosporium species—C. parasphaerospermum, C. chlamydosporigenum, and C. compactisporum—produce cold-active pectinases with optimal activities at varying pH and temperature conditions, with C. parasphaerospermum being the most effective.
  • C. parasphaerospermum achieved significant pectinase production through submerged fermentation, resulting in high specific activity and successful purification methods that increased enzyme activity substantially.
  • The pectinase from C. parasphaerospermum improved juice yield and clarity in various fruits, indicating its potential application in biotechnology for decomposing waste and enhancing juice production, although further studies are needed.

Introduction: Pulmonary aspergillosis is the main respiratory fungal infection however; its diagnosis is missed or delayed in critically ill non-neutropenic patients. Despite the utility of fiberoptic bronchoscopy for the evaluation of tracheobronchial aspergillosis (TBA) in immunocompromised patients has been extensively studied, however its utility in critically ill non-neutropenic patients is underestimated.

Objectives: To assess the bronchoscopic changes suspected TBA relative to the microbiological and histopathological aspects in critically ill non-neutropenic patients admitted to respiratory intensive care unit (RICU).

Aim: This study aimed to evaluate the efficacy and safety of laparoscopic management of common bile duct (CBD) stones in a single session in comparison with two-session procedures including endoscopic retrograde cholangiopancreatography (ERCP) and laparoscopic cholecystectomy (LC). The most popular approach to treat CBD stones that were detected before LC is with ERCP followed by LC. This two-session approach has some disadvantages, which include spontaneous passage of stones found on magnetic resonance cholangiopancreatography while awaiting ERCP, the risk for CBD stone passage between ERCP and LC or during LC due to excessive gallbladder handling, and the need for multiple anesthesia sessions and hospital admissions within a short interval.
